You can restore your previous version of windows from the System Restore Point by following these simple steps:

If you are upgrading your Windows using the Custom upgrade, the setup will backup a copy of your previous installation in the Windows.old folder. This backup folder exists only for ten days after the upgrade process. Therefore, if you are looking for a backup after upgrading your Windows, make sure to look for your files in Windows.old folder before they’re permanently gone.

To locate the Windows.old folder soon after the upgrade, follow the steps given below:

1. Launch Windows Explorer and navigate to the Local Disk C:
2. Open the C: drive and look for Windows.old folder.
3. Open the Windows.old folder and look for the files you wish to restore, select the files and move them to a convenient location in the current Windows installation.

Try to access the Windows.old folder within ten days after the upgrade, after that the folder is automatically deleted from your “Local Disk C:”

Note: If you are doing the clean installation, then the setup will not back up any data from the previous installation.

If you are upgrading from the existing Windows environment to Windows 11, the setup will ask you to sign-in using a Microsoft account. The data from the previous installation will end up moving to the Administrator account, which is automatically disabled after the new upgrade.

To recover data from the previous installation, you need to enable the built-in local Administrator account. Follow the steps as:

• Go to Start >> Click on the Search box >> Type Computer Management and click on the Computer Management icon.
• Navigate: Computer Management >> Local Users and Groups >> Users.
• Right-click on the Administrator account and select Properties.
