@nprofile1q... the weirdest bit I've had so far is Explorer utterly losing the ability to see filesystem changes.
Which doesn't seem like much until it starts happening. Delete a file? Nope, still there. Just kidding, it's gone after an F5.
Absolutely everywhere too.
✔️ Normal drives
✔️ Removable drives
✔️ Network shares
✔️ WSL filesystem
✔️ Desktop (arrrrrghhhh)
…and after a reinstall (after, I'll note, a proper self-destruct into unbootable state) it's gone. To this day I have no idea where that came from.
