You have some folders, that should not be there (unless upgrading): ESD, SysReset, Windows.~WS
As it was suggested, try some cleanup, including drivers, considering, that your Windows is huge.

Code:

fsutil usn deletejournal /d /n c:del "%LocalAppData%\Temp" /s /f /qdel "%temp%" /s /f /qdel "%WINDIR%\Installer\$PatchCache$" /s /f /qdel "%WINDIR%\Temp" /s /f /qdel "%WINDIR%\WinSxS\Backup" /s /f /qreg add "HKLM\Software\Microsoft\Windows\CurrentVersion\SideBySide\Configuration" /v "DisableResetbase" /t "REG_DWORD" /d "0" /fDism /Online /Cleanup-Image /StartComponentCleanup /ResetBasecleanmgr /sageset:65535 & cleanmgr /sagerun:65535

Download DriverStore Explorer 0.9.39 to remove old drivers.By the way, TreeSize shows the size incorrectly (size=allocated), you might try WizFile.

ESD deleted.
SysReset deleted.
Windows~WS deleted.
There wasn't much in any of them, ESD had 0 bytes, didn't make any impact on the overall size.

Run code through command prompt as admin.Not done.

DriverStore Explorer DL'd, RUN, not sure what is safe to get rid of and what to keep ... Will post a scan and ask for advise.
Attached the export file for opinions on what to delete.
I have an idea as to what, and a system restore is there to back me up ... I'd just rather not have to do it.
driverstore export.7z ... Wont attach a csv file, had to zip


WizFile kept crashing, its a better program than TreeSize, but really needs some updates or something. Will stick with TreeSize for now.
NOTE ... Will DL windrstat as well.

WizFile did show that 46% of the reserved space on C (Not the unused) is being occupied by 3465 files. I bet its error reporting or something similar. Deleting files/folders is fine, its not the r00t of the problem. Need a fix, not a patch.

You can try Wiztree, if Wizfile is crashing.

Do you have some kind of symbolic links on your drive? Onedrive or other Cloud solutions with large files?

One drive has been turned off, it was interfering with the W7 BU to my G drive.

There goes another guessing

Regarding to pictures in 1st post, that 58 GB missing is in backup files ($SysReset.. folder) Not familiar, how that Backup and space reservation works...)
