What Is windows.old And How To Remove It

If you notice windows.old folder in one of your disk partitions and are wondering what is it then this post will help you to know more about it. And also how to remove it completely.

Open the Start Page. Search for “Disk Cleanup“. Choose Settings. And then select ‘Free up disk space by deleting unnecessary files‘.

  • And then click Ok.
