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.
Work has rolled everyone over to Windows 11 and I have to agree with many of the other replies. It’s the most half baked OS they’ve released in a really long time. Really idiotic stuff happens… Like the snapshot and calculator tools just randomly refusing to start. And Outlook randomly refuses to recognize certain key inputs for a few minutes at a time (while other running apps continue to work just fine). Just really annoying.
Same, I just figure if they want to use windows, then they need to accept all the work impacting problems and stoppages. Just like how they accept the security implications of an all windows network…
It’s so entrenched though, and the typical user doesn’t know any different there days so it’s all windows and cloud now. I’m not saying there isn’t a place for these things, but it doesn’t have to be the default all the time…
Don’t think it’s just an Outlook thing, same thing happened to me in the file explorer. Weird thing is I opened another explorer window and that worked fine, while at the same time the other window was still unresponsive.
Just windows 11 failing at windows sometimes. ¯\_(ツ)_/¯
I too have experienced the funky unresponsive File Explorer bug. A second window worked even while the first was still unresponsive.
My scrollwheel input from my mouse will just stop working for a bit in a certain window. But will continue working in a different window.
