Delete the Windows.old Folder and Save Space (Again)

  1. The Windows 10 Anniversary Update brings a number of new features to Microsoft’s latest operating system – some more significant than others -- but expect some annoyances as well. Windows 10 is a solid operating system that is receiving a good slew of bug fixes and feature enhancements free of charge, on a potentially free OS upgrade (if you came from a Windows 7 or 8 PC).

    After the update you may notice some icons and shortcuts you had probably deleted, like the Windows Store or the Edge browser icon on the taskbar, have been added back. That's just old Microsoft keeping to old ways, but that's easily fixed. Deeper Cortana integration has also been a controversial subject ahead of the Anniversary Update release, but for the most part this can also be tweaked, disabled or ignored completely.

    Now, something that may not be as obvious is that the big update is treated almost like a Windows upgrade. To keep on the safe side, Microsoft's install setup saves a full copy of your current Windows installation (that's the Windows.old directory right there), and while this will come handy in case something goes wrong or you need to revert back, it will also occupy several gigabytes of precious storage.

    Once you already have the Windows 10 upgrade, you can create a USB installation with Windows 10 via software freely available on the Microsoft site (You need to be registered as having the upgrade). I did this and was able to completely wipe my drive clean of all data and partitions. I created a new partition and was able to install a "Full" Windows 10 install for free, without re-installing the original OEM operating system, in my case it was Windows 7, make sure you choose the "Home" version if you got the free upgrade. When I did the upgrade I had a lot of bugs and glitches, now with a full install my Windows 10 installation is running perfectly and there is no Windows.old folder because I didn't upgrade. Just putting this out there for those who don't know that this is an available option.

    No! Make sure you choose the edition you are upgrading (or did upgrade) from.

    Faster way from Microsoft help:
    1. In the search box on the taskbar, type Settings, then select it from the list of results.
    2. Select System > Storage  > This PC, then scroll down the list and select Temporary files.
    3. Under Previous version of Windows, select Delete previous versions, then select Delete.

    Thank you. I was able to remove 16GB of old installation and temp files.

    Indeed, that works, too. Be careful what you select however because it lists your downloads folder within the temporary files and you may be storing valuable stuff there you just haven't moved elsewhere yet.

    Using Touch on all of those check boxes looks as unfriendly as ever (fat finger touch results in check one, UN check the one above/below for those wondering), among other UI issues with Win 10 in a Touch only environment (and having it reset to defaults after is irritating as well).
    Member of the Preview, and disheartened about the rhetoric regarding input/suggestions from that program improving the Win 10 experience. Guessing that there are too few Touch only users to move the needle, as, in That environment, the Win 10 Microsoft apps' UI is a PITA at times.
