Your need to reinstall Windows might be due to a variety of factors. The benefits include faster computer speeds, less downtime due to system faults, and removing viruses. However, there are situations when it is necessary to reinstall Windows, and doing so will always result in some lost data.

Is there a way to get my files back after reinstalling Windows 11? Don't stress out. In this post, we'll discuss the strategies for recovering lost data after a reinstall of Windows 11.

File Recovery After Reinstalling Windows 11

If you need to restore files after reinstalling Windows, use one of the following methods:

🔖Use Windows Backup File History

Use a data recovery tool if you don't have a recovery option. When you use Windows File History to create a backup of your important files, you can easily restore them using the aided restoration feature. Here are the actions to take:

  • Select "Update & Security" from the "Settings" option.
  • Select the "Backup" option to locate your backup.
  • Go to "Back up using File History" and choose "More choices."
  • Click the "Restore files from a current recovery" button in the "Related settings" section.
  • Browse through a file's iterations using the arrows after you've located it. Restore lost data from a File History backup after reinstalling Windows.
  • Select the desired version and then click "Restore" to return it to its original state.

You may change where it's saved by right-clicking "Restore," then clicking "Restore to," and finally choosing a new location.

🔖Use System Restore Point

An older version of the files may be retrieved via backups or by using a restore point. When your computer detects a change, it immediately generates the file for you. Never back up data on the same disk that hosts Windows.

All your files will be lost if you format or reinstall Windows. Therefore, it is suggested that you save files to different partitions on your computer or to an external hard drive, DVDs, or CDs. If you want to restore files using a System Restore Point, do as instructed below.

  • Open the Control Panel and choose Recovery.
  • Pick the restoration point, continue by clicking Next, and then finish. 

Note: Make sure that your security settings are enabled. Click Configure System Restore, then Configure, then Turn ON.

🔖Use Windows File Recovery

Microsoft's free data recovery software has two distinct ways. The standard mode is for recently deleted files, whereas the extended mode is for formatted ones.

Following are the steps to start the process:

  • Initiate the process by downloading the Windows File Recovery program from the Microsoft Store. To start, launch the program.
  • A command prompt will appear once you launch the software; from there, you may learn how to use the winfr command. Data may be retrieved from the Y disk to the D drive using the following command: winfr Y: D: /extensive /n *test

The procedure will not continue if the command is not written correctly.
