    Get Wiztree, unzip it, run it as admin, scan C:\, see what is actually taking up space.

    Skype hasn't been a thing for over a year it has no place on any computer to begin with.

    @emet expand the PowerPoint folder and see what is there.
    Expand your Windows folder and check what's there as well.
    Show your whole AppData\Local content, we only see Edge here.
    Also, do you have Hibernation enabled? If you'd like to straight up test, open cmd or powershell as admin and execute
    Code:
    powercfg -h off
    see if you gain free space.

    @emet
    I'm looking at your spreadsheets/screenshots here and I'm wondering if you've ever cleaned up your computer, i.e. removed old unnecessary files. Personally, I don't think so. And if you have, how did you do it?
    This is indicated by the fact that some of your folders are terribly large.

    @emet delete all .tmp files from the PowerPoint folder.
    Look for cleanmgr in start menu and run it as admin. Tick all the checkboxes and see how much space it will calculate can be freed up.
    You can manually delete %AppData%\Local\Temp and Windows\Temp contents.

    Apart from these simple things, you can also check the condition of your component store by executing
    Code:
    dism /online /cleanup-image /analyzecomponentstore
    Then, if there's a lot of accumulated backups, you can clear them by executing
    Code:
    dism /online /cleanup-image /startcomponentcleanup
    Generally, your Windows, Program Files and Users folders are notably large. You may need to check what apps you have installed and uninstall the unused ones.
    You have 122-7=115GB of used space, where Windows, Program Files and Users folders make up roughly 108. This also leaves some 7GB that I can't see on the screenshots but i'd assume Program Files (x86) and other misc things.

    Show your entire Windows folder. WinSxS is only a small part of it.

    The Windows directory may be a red herring. Many of the files are hardlinked from the Side by Side Store to the Windows and System32/SysWOW64 directories, that's how Windows works. Unless that program correctly accounts for hardlinks, it may count many files multiple times.

    uninstall Adobe Acrobat then reinstall can recover 2GB~3GB
    thanks to Adobe to keep all updates instead keeping only the latest cumulative update.

    be careful powercfg -h off disables hibernation which drains battery if laptop is not turned.

    Locations to check maybe:

    Code:
    %SYSTEMROOT%\MEMORY.DMP
    %SYSTEMROOT%\Minidump
    %SYSTEMROOT%\Temp
    %LOCALAPPDATA%\CrashDumps
    %LOCALAPPDATA%\Temp

    Maybe you have a problem with the "CapabilityAccessManager.db-wal" file? (Microsoft Confirms Windows 11 Bug That Can Consume Over 500GB of Storage Through Permission Log File).

    Well, worth a shot.
    Did you check your Restore Points? They can fill up a drive, but will usually be reduced if the free space falls below a certain level.
    Furthermore, the %SYSTEMROOT%\SoftwareDistribution\DataStore\DataStore.edb file can get huge, sometimes.
    Other than that, I'm out of ideas.
