TEST created two years ago to get rid of Windows.old

Edit: Reread your question, I would rename or delete that folder and leave it for a few days, If you delete it leave it in the recycle bin for a few days just to be on the safe side, Then permanently delete it.


Yes it is safe To delete that folder, It is fairly easy.

There is a tutorial written by Brink on Ten-forums that should help you out.

Thanks for the reply. I guess I wasn't specific enough in my original question. I had meant to say "is it safe to delete the Folder called TEST which within that Folder is Windows.old but a bunch of other stuff, such as Appdata / Application Data / Local settings / Nethood / Start Menu etc etc."
Everything in there is marked 2014-12-05 except Windows.old which is dated 2016-08-25 AND a NTUSER.DAT and get a load of this! This one is dated 2017-11-13. Yet, when I right click on that file, I get a different date showing 2014-12-05 but modified 2017-11-16. It's becoming more weird all the time. My question furthermore would be, what is a file that new doing in here?
I seem to remember her creating another account on this system, moving that stuff over there and then deleting the new account that was created. She told me the Windows.old Folder would self destruct within thirty days but that's two years ago and it's still there but zero contents.
I have this phobia of removing anything right now but was wondering if it was actually just garbage hanging around for nothing. I would think because of two major updates since then, it should be ok. So would you say the whole Folder called TEST still would be safe to remove?

Yes I would delete it.

If you really want to make sure there is no problems just rename the folder and if all is well after a couple of days you can delete it.

That files in folder remains could be just links, not actual files. (that is one possible explanation).

Why MS (or Windows) does it? Could be bug, could be that in some occasions, files are left in Windows.old that couldn't be copied to new locations. Too many possibilities.

I would recommend backup before you manually delete this folder (if system can't do it with system tools..). Make a Macrium image (it is a good idea anyhow) and delete it.

If you get message that folder couldn't be deleted: Open command prompt (admin)

RD /S /Q %SystemDrive%\windows.old

If disk cleanup didn't remove the folder, I doubt system will do (after 30 days or so...) Making backup Image is always a good idea, if you don't have any. It is quick and cheap, but pure luxury, if something goes wrong
