I see, restoring your PC to an earlier point in time can be a good way to recover lost or deleted files. Based on the error message you received, it seems that the restore process is encountering an issue while attempting to delete a file.
Here are some additional steps you can try to troubleshoot the problem:
Disable your antivirus software temporarily and try running the system restore again. Sometimes antivirus software can interfere with the restore process and cause errors.
Run the system restore from Safe Mode. To do this, restart your computer and press F8 repeatedly until the Advanced Boot Options menu appears. Select "Safe Mode" and log in to your account. Then try running the system restore again.
Run a disk check to make sure that there are no issues with your hard drive. To do this, open Command Prompt as an administrator and type "chkdsk C: /f" (without quotes) and press Enter. This will scan your hard drive for errors and fix any issues it finds.
Try running the system restore from a bootable recovery drive. This can help to isolate any issues with your operating system or hard drive that may be causing the problem.
