Windows 10: Free space on harddrive randomly jumped from ~65 GB to ~108 GB

    Free space on harddrive randomly jumped from ~65 GB to ~108 GB


    My laptop is on Windows 10.

    Normally, I only use my laptop when I am out of town. A few weeks ago, I had about 65 GB of free space on my main partition.

    A couple days ago when I started my vacation, I noticed that it jumped up to 74 GB. I presumed that was because some older system restore points were getting deleted. Today, I dumped about 2 GB of pictures onto my second partition. I left my computer on for a few hours as I uploaded pictures to facebook and did a virus scan.

    Kaspersky says my computer is clean, but I know noticed that my main partition all of a sudden has ~108 GB free. Windows also says that I am using about 20 GB of System Restore points (out of the allocated 30.50 GB). I also noticed that my Windows.old folder is missing from my upgrade.

    Any idea what is going on? (When I installed Windows 10 in mid-May, system restore was disabled and I had about 110 GB free)

    Looks like you lost your opportunity to revert back to your previous O.S. After upgrading to Win 10 you have 30 days to revert back. After 30 days, your Windows.old folder will magically be removed. No going back now.

    I have no intention of going back to Windows 7. My first month finished on the 21st (and I didn't use my computer at all that day), so on the 22nd and today I presume Windows was deleting Windows.old in the background.

    It is a bit startling that that folder was ~40 GB big. I did an MBAM scan and an AdwCleaner scan, and I found no problems. Is it safe to assume there was no virus issue but it was just the Windows.old folder disappearing?

    Completely ruling out action by a virus is very difficult to do but there really is no evidence of this. What you are saw is a normal operation.

    The scheduled disk cleanup likely deleted a bit more than just the windows.old folder. Run it manually and you'll see a lot of other options listed.

    It also deletes downloaded files for upgrade and 4 or so GB are just in there. Windows.old has all system files and programs installed so it's about as big as your old system was. There's a lot of GBs in there.
