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.
Yeah, the one and only PC on which I ever used Vista was a comically under powered laptop that my Mum bought. If it was running XP it would have been solid, but alas, it had 512mb RAM and Vista was thiiiirsty.
