Is it safe to delete the "Windows Old" folder that is residing on C drive and taking up valuable space, please?

Once deleted you cannot go back to the older version. anniesboy68 16:46 25 Feb 2016 Thanks, will check BT 17:15 25 Feb 2016 Don't just delete it, its important to follow the instructions here Delete Windows.Old folder I just did mine today along with lots of other stuff and my laptop is working so much faster.
