How to return a file to its previous version. How to return to the old version of Android after updating

In this article, I will tell you about a way to automatically save the latest changes to your files in Windows 7 once a day, in case you accidentally delete some necessary document or, for example, change it and save it without leaving an old copy. This method consists of saving previous versions of files using the built-in function in Windows “System Protection”, i.e. by creating restore checkpoints.

When deleting files from a computer, the “Recycle Bin” usually comes to the rescue, in which the file is placed before final deletion. From there, you can always restore the file and continue working with it. However, there are several nuances here:

Firstly, the volume of the recycle bin is limited (it is configured by the user himself) and some large files will not always be deleted immediately, past the recycle bin.

Secondly, the recycle bin can be emptied as a result of careless work in some system optimization programs, or you can empty the recycle bin yourself and then remember that there was something important there :)

Thirdly, in Windows the Recycle Bin sometimes glitches and when you open it, sometimes you may not see any files, although they actually are there.

Therefore, you definitely shouldn’t rely completely on the Recycle Bin in the sense that it will save all your files from accidental deletion... Well, in the end, the Recycle Bin will not save your file in any way if you accidentally changed it, then saved it and after some time, you suddenly need an original copy of the same file (for example, if the changes you made were incorrect and you need to take the original file and start over). After saving a file, there is no way to return its standard copy.

To have additional protection for your files from loss or unwanted, unnecessary changes, in Windows 7 you can use the System Protection feature. This feature is part of a tool to restore the system to a previous state. Windows has a special program that constantly monitors the state of the system, monitors its changes and saves important changes in the form of recovery checkpoints. Thanks to these restore points, Windows can be restored to one of the previous states, for example, the last day, week, month (depending on which restore points were created).

More information on how to restore Windows to a previous state is described in a separate article.

Windows 8 and 10 have a simple and convenient “Backup Service” function for setting up a full backup of your selected files and folders to another hard drive at a specified time. This has been discussed.

In addition to the fact that the system protection function monitors system parameters and writes changes to special recovery checkpoints, it can also monitor changes to files that are also written to checkpoints, which allows us to then view the history of each file.

There is an important point. You can only see previous changes if you created a restore point in Windows before those changes. For example, you deleted a file from your desktop and a restore checkpoint was created up to this point. This means that you can then look at previous versions of the files in the desktop folder and see the file you deleted there. If a recovery checkpoint was not created before deleting the file, then you will not be able to restore it.

The same applies to changes in files. For example, you made some change to a file, saved it and then wanted to restore the original version of this file. This can only be done if a recovery checkpoint was created before the changes were made. Those. you will get 2 versions of your file: the one that was saved when creating the checkpoint and the file you modified.

The function of saving previous versions of files is not a full-fledged backup, since firstly, checkpoints will be created on the same disk where you store the original files. This means that if your hard drive suddenly fails, you will lose your files along with their saved previous versions. Secondly, if the system fails, you can restore previous versions of your files only by restoring the system to a working state!

Setting up saving of previous versions of files

To enable saving of previous versions of files, you need to go to the “System Protection” section.

This function can be quickly opened through Windows search by typing “Create a restore point” there. In the search results you need to open the found option of the same name:

Learn more about how to use search in different versions of Windows.

You can also open the desired section manually by going to Start > Control Panel > System and Security > System > System Protection.

In the “System Protection” window, from the list (1), select the local drive for which you want to enable the ability to save previous versions of files and click “Configure”.

At the top of the window, select one of the options: save both system settings and previous versions of files, or only previous versions of files (1).

In the first case, when creating the next checkpoint, Windows will save not only your files, but also system settings, which will allow you, in the event of any failures due to incorrectly configured parameters, to return the system to the state when these failures did not occur.

Below, using the slider (2), you need to indicate how much space as a percentage of the total space on the selected local disk will be allocated for storing previous versions of files and system settings (if you selected option 1 above).

Remember that if the allocated free space for storing checkpoints runs out, old checkpoints will be deleted.

To save the changes, click “Apply” and “OK”.

If there are several disks, then you will need to separately select each disk from the list and enable saving of previous versions of files!

How can I view previous versions of files?

If you are viewing previous versions of a file, the window will display a list of versions of the selected file, along with dates of modification. To view changes in a file, you need to select it and open it by double-clicking (or using the “Open” button at the bottom). This way you can look at different versions of the file you need and find the one where the changes you need were made.

To restore the selected version of a file, the easiest way is to drag it with the mouse from this window to the desired folder. The file will be restored immediately. If you click "Copy", an explorer will open where you can select a folder to restore the file. And if you click “Restore”, the file will be restored to the same folder where it was previously located, and if the same file (of a different version) is already located in this folder, then it will be replaced by the version that you are restoring.

If you are viewing previous versions of a folder, then the window will, accordingly, display all changes saved in recovery points in this folder.

Likewise, by opening different versions from this window, you can find the one you need and restore it.

How can I change the schedule for creating checkpoints?

By default, checkpoints that save changes to your files are created in Windows 7 every time you turn on your computer and at 0:00 every day.

This means that changes to your files will be saved twice during the specified periods. That is, if your file, for example, is changed during the day and you want to return these changes, then you will not be able to do this, since you initially do not create restore points during the day.

You can always change the schedule for creating restore points to your own. For example, the initially set time of 0:00 may be meaningless for many, because not everyone already uses a computer at this time of day. And if the computer does not work at the specified time, then the checkpoint, accordingly, will not be created.

In order to change the schedule, you need to use the task scheduler program built into Windows.

Open Task Scheduler by typing "Scheduler" in Windows search:

On the left side of the Scheduler window, navigate to Task Scheduler Library > Microsoft > Windows > SystemRestore.

A task named “SR” will appear in the center of the window. Right-click on it and select “Properties”.

You can view and change the current schedule for creating recovery checkpoints on the Triggers tab (1). It is better to leave the “At startup” task. But you can change the “Daily” task by specifying a different time for creating points. Select "Daily" (2) from the list" and click "Edit" (3).

In the settings window that opens, change the time after the word “Start” to one that is convenient for you.

It's best to choose a time when your computer is most likely to be turned on. Click "OK" to save the changes.

You can create a manual restore point at any time, if necessary. To do this, in the already familiar “System Protection” window, you need to click the “Create” button.

And in the window that opens, specify any name for the control point and click “Create” again.

In a few seconds the point will be created!

Using the task scheduler, you can configure any programs to autorun on a schedule, for example, when you turn on the computer. This is discussed in a separate article.

Conclusion

As a result of the manipulations performed, you will have a checkpoint created every day at the time you specified and as a result you will receive a backup copy of your files for every day. However, this method of saving previous versions of your files should not be confused with full-fledged backups, because full backups are always performed on a separate hard drive so that files are not lost even if your main drive fails. In Windows 7, unfortunately, there is no way to configure the quick creation of previous versions of files using scheduled backups to another hard drive. In this Windows, is there only such a simple option with recovery checkpoints, which was described in this article, or the ability to create an archive with the necessary data, which is already a reliable backup method and will be discussed in one of the subsequent articles.

Surely you have heard about the Android operating system, unless you yourself are the owner of a device running this shell. This platform has appealed to a good portion of gadget owners and is the most common OS among mobile devices. Since 2009, when the first version of the “robot” was released, the developers have not stopped improving and modifying their brainchild. New versions and updates are released regularly. But do you always need to update your device and how to return the old version of Android after updating? We will talk about this in this publication.

Why are updates needed?

First of all, for the proper operation of the system. Developers optimize performance, improve the interface, correct lags, because it is almost impossible to release a perfect system right away, and minor faults will only be noticeable during its active use. In most cases, you can find out about the availability of an update using a regular message that appears in the notification line. You can upgrade by going to the update center, downloading and installing the new version.

Why might gadget owners be unhappy with the update?

In most cases, after the update procedure, the device should work faster, and all shortcomings should become a thing of the past. All that users can complain about are some changes in the interface or, for example, the disappearance of shortcuts from the desktop (accordingly, the applications themselves disappear). This happens because the installed programs are already outdated and simply do not correspond to the new firmware.

New versions of applications or their analogues can still be found on the Play Market, and trying to return the previous version of the OS due to the loss of old applications is a rather stupid idea. What else can irritate owners in the new firmware version is the appearance of some programs that cannot be removed. For example, these could be new services from Google. And then all users begin to think about whether it is possible to return the old version of Android. But most of all those who want to return to the old firmware are among those who tried to reflash their device on their own. Here, a huge variety of problems may appear, to the point that your gadget may turn into a “brick”, that is, it may stop showing signs of life altogether.

So before performing such manipulations, make sure that you have enough knowledge and experience, and best of all, contact a professional. Reflash the device only in extreme cases, when you cannot do without it, because such a procedure completely voids your warranty. But you can still return the previous version.

How to return to the old version of Android after updating?

First, come to terms with the fact that standard system resources do not provide a system rollback option, such as in the Windows OS. Accordingly, when you return to the old version, all installed programs and personal files will be deleted. Therefore, immediately before the procedure for returning the old version, make backup copies of all important documents, files, phone numbers, and so on. Be prepared to say goodbye to user settings, saved accounts or applications, they will be erased, everything except the built-in ones.

Next, you will have to perform a factory reset yourself. How to do this depends only on your version of the operating system, but most often this item is found if you go to “Settings” and “Recovery and reset”. This parameter can also be found in “Confidentiality”. In any case, finding a factory reset will be easy. Next, you will need to perform a series of actions that are a little more complicated, that is, enter recovery. And how to return the old version of Android using it - read on.

Login to recovery

"Recovery" is a special boot mode on Android, with which you can reset settings or flash the system. If you buy gadgets in trusted certified stores and with an already installed OS, then they should have the stock “recovery” mode. How to enter recovery depends only on your device model. The most common combination is the power button and the volume down key.

For example, if you don’t know how to return the old version of Android to Lenovo, then this combination will work for most of their devices. I would like to note that before entering recovery, you need to turn off the phone. If you are looking for how to return the old version of Android Sony Xperia, then you need to press three buttons: those that we have already named, and the camera button. You can easily find more detailed instructions for various models on the World Wide Web. But what to do after entering boot mode?

How to return the old version of Android after updating through recovery mode?

You can navigate through the menu using the " key" highlight", and to select a specific item you need to press "select". There is no need to be afraid of this mode, if you understand it well, it becomes clear that there is nothing complicated. Now look for the line with " wipe data / and select it. A new menu will open in which you will have to confirm the action. Afterwards, wait for the reboot and the OS will return to factory settings.

Charge your smartphone

What is worth noting first of all is that before starting this procedure you need to charge the device well. It doesn’t matter how long it takes to roll back the system and how long the gadget will reboot after that.

If during such manipulations in the “recovery” mode the device does not have enough charge and is unable to complete its task, then, most likely, problems with its further use cannot be avoided.

The same applies to flashing your phone yourself. For some users, certain system functions disappeared or did not work, even the touchpad became inoperable. In some cases, the firmware did not install at all and it was simply impossible to enter the OS. But even then recovery helped again. If you cannot enter this mode or it simply does not exist, there are a number of simple utilities for flashing this mode directly through the operating system. Sometimes you may need a PC for this task.

We told you about how to return the old version of Android after updating. Treat your gadget with care and it will serve you for a long time.

Good day everyone!

When searching for and updating drivers, it happens that the new driver begins to work unstable: it causes conflicts, errors, does not perform some functions correctly, etc.

In this case, it is recommended to roll back to the old previous driver, which previously worked in normal mode. I note that even if you did not make a backup of your drivers (or restore points in Windows), in most cases you can still restore everything (since Windows does not remove the old driver, and it remains in the list of available ones on the PC) .

In this article I will show you with several examples how this can be done.

Addition!

You might find this article useful on how to remove old (or unnecessary) drivers -

1) Via device manager

Option #1

There are two ways to roll back a driver through Device Manager. I like the first one because when you roll back, you can manually select the driver version that you need. I’ll show you with an example how you can restore an old working driver to a video card. So...

First we open device Manager . To do this, go to the control panel, enter “devices” in the search and among the results found there will be a link to the desired manager (see screenshot below).

Then a menu will appear with a choice: perform an automatic search or manually on this PC. We choose the second option (see example below).

If you had several versions of drivers on your PC, you should now see a list of them. Be guided by dates, versions and title. By choosing any of the versions, agree to the installation.

All! The screen should blink, and then you will see a message indicating the successful (or unsuccessful) completion of the operation. An example is presented below.

Option No. 2

You can roll back the driver in another way: after finding the desired device in the manager, open it properties.

In properties, open the "Driver" tab - at the bottom of the window there should be a button "Roll back". I note that it is not always active (even if you recently updated the driver). Therefore, I recommend first trying the first rollback option (described above), and then this one.

Roll back the driver (if the device does not work after updating)

2) Using System Restore

If you have system restore points (and by default Windows does them (except for ten)) , then you can try to roll back to the old driver using system restore.

How to see if there are restore points and run System Restore:

3) Using special Driver backup utilities

I couldn’t help but mention this method in this article. True, in order to use it, you need to make a backup in advance (perhaps someone will find this method useful in the future).

The essence of the work is approximately as follows:

Hello everyone, dear users of iOS devices – iPad and iPhone. In today's article I will tell you how you can return the previous, old version of iOS. Why might this be needed? For example, you updated to a new version of the operating system, you don’t like it and want to return to the previous version of iOS. You won’t be able to do this (return) using standard methods; you will have to carry out some manipulations.

The process of “rolling back” to an old version of the iOS operating system is as follows:

• Select and download from the Internet the version of the iOS operating system you need.
• Connect your gadget (iPad or iPhone) to your computer and launch iTunes.
• Adding the downloaded version of iOS to iTunes, then automatically rolling back the system.

But, before you start restoring the old version of iOS, I want to clarify a few points:

• Before starting work, be sure to make a backup copy of your iOS device, this will prevent you from losing data if the rollback fails.
• You will not be able to or the iPad is too old versions of iOS, for example, iOS 6 and below. Apple simply stopped signing (activating) these versions. Perhaps by the time you read this article, Apple has stopped signing iOS. Before rolling back, please take this into account.
• The rollback process is painless for your iPhone or iPad, even if you fail to rollback successfully, you can always restore your iPhone or iPad. But in any case, you act at your own peril and risk.

So let's begin the process of upgrading your iOS operating system to an earlier version..

First of all, before you downgrade, you need to download the version of the operating system that you want to install on your iPhone or iPad. I’ll say right away that you can download iOS completely free of charge. So, let's move on to the download process:

• Follow the link - http://www.getios.com/.
• In the “YOUR DEVICE” field you need to select the type of your mobile device. For example: iPhone or iPad.
• Next, in the “THE MODEL” field you need to select the model of your device. For example: iPhone 4s or iPad 2 Wi-Fi.
• Next, in the “iOS VERSION” field you need to select the version of iOS that you want to install on your iOS gadget.
• To complete the entire operation, you need to click the “Download” button, after which the process of loading the operating system will begin.

So, after the file with the system is downloaded to your device, proceed to the next step.

Move on to the fun part - replacing iOS with an earlier version. To return iOS, follow these steps::

• Connect your gadget to a personal computer on which the latest version of iTunes is installed (if the program is not there, then you need to install it. You can download it from the link - http://www.apple.com/itunes/download/).
• Launch iTunes.
• In the side menu (if not visible, press CTRL+S) select your device.
• In the field that opens, in the “Overview” tab, find the “Update” button.
• Hold down the Shift key (if you have Windows) or Alt key (if you have a Mac) and click on the “Update” button. A window will open in which you need to select the previously downloaded file with the operating system.
• After all the steps described above, the iOS version will begin rolling back. This usually doesn't take much time.

That's all for today, I hope this short note helped you, you were able to return the version of iOS that you need.

I would be grateful if you leave a comment. To do this, you can use the comment form from the social network VKontakte. Attention: in order to be able to leave comments you must be logged in to VKontakte.

Let's see how to roll back Windows 10 back to the previous version of the operating system after updating the system to a new build. Microsoft regularly releases new versions of the Windows operating system.

With each new version of the operating system, settings and operating parameters change to a greater or lesser extent compared to the previous version. After updating to a new build of Windows, some users are experiencing problems with their computer.

Problems can be of an objective nature: some applications stop working, problems with drivers, etc. It is also possible that there is a subjective perception of the new version: it seems that in the previous version everything was simpler, more convenient, faster, etc. Therefore, there is a need to return to the previous build of Windows that was running on the computer before the system update.

With such circumstances in mind, I provided the opportunity to return to the previous version of the operating system.

If the user decides to go back to a previous version of Windows, there are two options to resolve the problem within a limited period of time:

• Rollback to a previous version of Windows if you upgraded from Windows 7 or Windows 8.1 to Windows 10.
• Return to the previous version of Windows 10 if the update occurred on Windows 10.

At the moment, you can roll back the system to the previous build within 10 days (previously the time period was limited to a month) from the moment of updating Windows 10.

I have already talked about how to return from Windows 10 to Windows 7 or Windows 8.1. In this article we will look at how to roll back an updated build of Windows 10 to the previous version of the Windows 10 operating system.

How to return to a previous version of Windows 10 (1 method)

You can return to the previous version of Windows 10 directly from the operating system settings.

To initiate a rollback to a previous version of Windows 10, follow these steps:

1. Enter the "Settings" of the operating system.
2. Open Update & Security and then Recovery.
3. In the "Go back to a previous version of Windows 10" option, click on the "Get Started" button.

1. In the “Return to an earlier build” window that opens, you must specify the reason why you are rolling back to a previous version of Windows 10.

1. After you check the box in one of the items, click on the “Next” button that becomes active.
2. The next window prompts you to check for updates. They may be able to fix the problem with Windows 10.

1. Click on the "No, thanks" button.

1. In the "What you need to know" window, review the process of downgrading to a previous version of Windows 10. Please note the following points:

• The process of rolling back to a previous version of Windows will take some time.
• You will lose any changes you made to your computer after upgrading to the current version of Windows.
• Reverting to a previous version of the operating system will not affect your personal files.
• To avoid losing important data, make a backup copy in advance.

1. To start the process of returning to the previous Windows build, click on the “Next” button.

Wait for the return process to complete.

How to roll back a Windows 10 update (method 2)

The second method for returning to a previous version of Windows 10 is using the Windows PE recovery environment.

On a running computer, press the Shift key on your keyboard, then right-click on the Start menu. Select "Shut down or log out" => "Restart".

In the “Select Action” window, click on “Troubleshooting”.

In the Diagnostics window, select Advanced Options.

In the "Advanced Options" window, click on the "Return to previous version" button.

In the “Return to previous version” window, click on the account name.

In the next window, enter your account password. If there is no password, leave the field blank. Click on the "Continue" button.

To start the process of resetting Windows to a previous version, click on the “Return to previous version” button.

How to increase the Windows rollback period to 30 days

Microsoft has reduced the period when a user can return to the previous version of the Windows 10 operating system. There is a way to increase the period for returning to the previous version within 30 days, as it was before.

Prerequisite: Windows must have rollback files to the previous version on the computer. Do not delete system update files yourself.

During the first 10 days after updating Windows 10, you must complete the following steps:

1. Run Command Prompt as Administrator.
2. In the command line interpreter window, enter the command and then press the Enter key:

The countdown to the end of the period begins from the moment the system is updated to a new version, and not from the moment the command is executed. You can set a period of up to 60 days (the number after “Value:”). All this time, files from the previous version of Windows will be stored on the computer.

If, after executing the command, “error 1168” appears, then time has already been lost, and you will not be able to return to the previous version of Windows.

Conclusions of the article

If necessary, in case of problems or for other reasons, the user can roll back Windows 10 in order to return to the previous build of the Windows 10 operating system. You can use this opportunity immediately after updating the system, for a limited period of time.
