Personally, I have never seen this many issues with Windows like today. Even way back in the Windows Vista days. Woah, Windows Vista will be 20 years old in November…
If you are forced to still be on Windows 11.
This file can be found in the following directory,
C:\ProgramData\Microsoft\Windows\CapabilityAccessManager\
Then see if it shows a huge file size.
Windows Latest found that one particular file called “CapabilityAccessManager.db-wal” can use most of your system storage.
If your PC is affected, the safest fix is to install Windows 11 KB5095093 from Windows Update, or wait for the July 2026 Patch Tuesday update, where the fix is expected to roll out automatically.
XP was the first NT-version with a Home Edition. If you’d been running Windows 2000 at home you would’ve felt the same way (XP is basically just 2000 with a facelift, NT 5.0 to NT 5.1) and even NT4 was pretty good (though 2000 was better).
The 9x series (95, 98, ME) were built on a different kernel and designed specifically for home use and were, in comparison, terrible. ME was especially terrible as they tried to bring plug-and-play to the 9x core without NT’s hardware abstraction layer and shit did not work well.
