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.
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.
