How to recover files deleted or quarantined by windows defender on Windows 11?

Windows 11/10 comes with a very useful feature called System Restore Points. The best thing about it is that it's completely free, all the functions are built into the system, and it can be used locally without the need for a network, which effectively protects the user's privacy. It can restore a wide range of deleted files as well as the system state, however, the time required for restoration varies depending on the size of the restore point, roughly 5 - 15 minutes.

You can use this feature to recover files deleted or deleted or quarantined by Windows Defender:

1. Press Windows + S, type Create Restore Point, click Open, and make sure the protection status of the C: drive is on.

2. In the System Properties window, tap System Restore, select Next, and check the available restore points.

3. Select Restore point before file deletion, tap Scan for affected programs to confirm that the file may be restored.

4. Tap Next > Finish, the system will reboot and restore, after reboot, check the file 

5. If the file is not restored directly, check C:\System Volume Information (requires administrator privileges).

Note: This feature for recovering files deleted by Windows 11 Defender relies on enabling restore points in advance, and cannot be used if they are not set up in advance. The operation is complex and uncertain, may affect other files, and there is no guarantee that every restore will be successful. In addition, files may not always be included in the restore point, and files added, modified, or deleted after creating a restore point may not be recoverable, risking data loss.
