    Does W10 upgrade delete windows.old files afer 30 day rollback period?


    I did an upgrade (not a clean install) to Win 10 Pro on an older laptop running Win 7 Pro. This was just over 30 days ago. All seemed to go fine and the system is working fine, with a few minor hiccups.

    I have no intentions to rollback to Win 7 so have decided to remove the windows.old folder and regain disk space. Looked at the properties of the windows.old folder and discovered it was empty. I then opened the Disk Cleanup tool>Clean up system files and could not find any Previous Windows installation option.

    Does the Windows 10 upgrade process automatically remove the windows.old files and the Disk Cleanup>Previous Windows installation option after the 30 day rollback period expires? I'm not really low on disk space (more than half is free) but would like to clean this up if possible or get an idea what happened to the windows.old files.

    TIA for replies

    Hello YC4719, and welcome to Ten Forums. :)

    Yes, the previous installation files will be automatically deleted after 31 days.

    Thanks for the quick response! I suspected that was the case but good to have confirmation that it was not some issue with the upgrade process for my system. Would it be OK to delete the empty windows.old folder? It just has 5 empty folders.

    One still wonders why, though Windows removes "most" of the content in this Windows.old Folder, why it can't be fully removed with Disk Cleanup. There are times when the Folder is not removed either and I'm one of those fortunate ones who knows. Microsoft Support created a new Account on my system, moved that Folder over into that, deleted the new Account and informed me Windows.old would disappear within 30 days. That was well over a year ago and the TEST Folder they created and the Windows.old File they moved over into that still remains. It did not remove itself or self destruct. Most interesting.

    I just found Windows.old did not have any files and you explained that, but what is not know is why it deleted the files after 31 says when I reset it to 60???????

    Could it have gotten reset back to default after a Windows Update?

    Not that I know of. I just went ahead and did a CleanDisk because I haven't seen any real problems with 1803.
