Step 1. In the ‘Settings’ of your PC, visit your ‘Update and Security’ section.

Method 3 for you: System Restore for getting your Lost Files

A restore point helps you recover your files and your OS. Yes, this means that your Windows Reinstallation will be undone. That is true if your Restore Point is older than OS Reinstallation. But remember, it also means that your files – lost after the reinstall – will return.

So, you can determine if OS Reinstall Reversal is okay for you. If not, you should focus on earlier two methods.

But, are you willing to reinstall your OS one more time? If so, the next steps are for you and your recovery efforts.

Step 1. You should access Run app. You can find it using Start menu Search option. But the key combo of Windows key and R key is your shortcut.
Step 2. After the Run box appears, enter “rstrui.exe” and press enter.
Step 3. Welcome to your System Restore window. Of course, you have the option ‘Choose a different restore point’ which you select. Then, click Next.

Step 5. Here, you find which drives are part of the Restore changes. If you confirm that your Data drives are safe, hit Next. But if your drives are going to change, backup them. And repeat the process as per the On-screen Guidelines. In short, even if your drives change due to a restore; your data remains accessible in your backups.

Thus, wait for the restoration operation to end. You should not try to interrupt this operation.

Note: Windows.old folder and your data recovery

Did you format your Hard-drive before installing your OS? If your answer is no, then your personal files have a Windows.old folder. And this folder keeps a copy of your data for twenty-eight days. So, even after a Reset or Reinstall of your OS, you can get back any lost files.
If you want them back, follow the guide below.

Get back your files from Windows.old folder

Access your ‘My Computer’ or ‘This PC’ app. That is, you want to open your File Explorer to see all drives.
You should select the Windows OS installation drive. In most cases, it’s your ‘C:’ drive.
You can locate a folder Windows.old and find ‘Users’ folder in it.
Then, you double-click your username folder.
After the above steps, you select the folders and files you want.
You can copy your selected data objects and paste them elsewhere. Remember, you should save them outside Windows.old folder.
Thus, you can repeat these steps again, for another user accounts on your device. All the best.
