How can I recover my data after installing Windows 10?

 

“I recently ran into a problem with Windows 10 update that resulted in reinstalling Win 10. My drive C was completely wiped clean, and I need to reinstall all of my programs. But my D drive (a separate physical drive) was not affected. Luckily, it saves my most data.

My question is: Is it safe to restore the backup to the C drive because the message says the selected hard disk is not empty? If I continue, all the data on the disk will be deleted. So, how to recover data from reinstalling Windows 10?”

- Question from a user

Yeah, in the field of computers, when there is a problem with the Windows operating system, users sometimes need to reinstall the Windows OS to restore it to a good status, but they don't want to lose data. Here are 3 different situations and recovery methods:

  • #1: Still don't reinstall Windows. Microsoft offers you the "Keep my files" option while resetting, which, as the name suggests, allows you to reinstall Windows 10 without losing data. Also, it's necessary to backup files (if possible).
  • #2: Already Reinstalled Windows. Microsoft still allows users to recover data from Windows.old folder created after reinstalling Windows. Note Windows will automatically delete it after 28 days.
  • #3: 28 days after Reinstall Windows. You need to check if there are any backups available or try reliable data recovery software. This is what we are going to focus on.
