    Windows update failed and took space


    A windows update I was doing failed at the "Configuring Updates" stage. After that it said it was reverting changes, but I later found out that the update took over 3 GBs of disk space. Windows Clean Up tool doesn't help.

    3Gb is a lot of space by anyone's standards, however, excessive disk space usage by Windows Update is one of my pet moans (I'm seemingly the only one to ever mention it though). What I find is that following a disk clean (make sure you use the clean system files option as well) is that free space returns sometimes a few days, sometimes a week or so later, but it always returns. This months updates used around 1gb of space but nearly a week later and I'm actually 1.1Gb up on the deal.

    I'm surprised others don't mention this but there you go... whether yours will return due to a failed update I can't say for sure, but do run the full system files clean and see what happens. A browser clean does no harm either, I usually combine the two following updates and then finish with a defrag of the HDD.

    Sounds (I say all words when reading...) like the C:\$WINDOWS.~BT might be full given the number of GBytes you mention.

    Post-post-aside: I just read somewhere or other that uSoft is going to download automatically all the files for a Windows 10 Upgrade to users whether or not they have decided to upgrade. This might only happen if users have selected "automatic download and install" for regular updates.

    I lost 4GB with the updates from this month, but still have nothing back

    Those sound big big numbers to me, more like what you would expect if W10 upgrade files were being stored somewhere. Perhaps worth checking the folder brokensoftware mentions above. I don't have Windows Update set to automatically install, perhaps that is why I haven't been nagged with the W10 update 'App'.

    I do not have that folder anymore, since I finally had the chance to download windows 10.
    I unreserved to prevent windows 10 from downloading and deleted the folder.

    Dunno then. I've regularly seen freshly installed updates take around 1GB, but never more than that... which is bad enough, but the space does always return as I mentioned. Not system restore points taking the space ?

    I created a backup of my system 2 days ago as I weekly do and to save space I deleted the restore points before.

    If you use imaging software then its definitely worth rolling things back a week and having another try and see what happens. Note the space before and after and make a note of the updates offered.

    Already did all of it
    Inclusive the updates that I already had installed (office updates from years ago) it was around 1GB.
    Before installing, I had around 75GB free space.
    After installing, I had 71 to 70GB free space left.
    Right now it is at 71GB free space, but I'll watch how it goes.
