I don’t expect troubleshooting, but it’s not isolated to just my company, my home computer did it too, not nearly as often, and it’s been a while since it’s happened there (probably since I only leave file explorer open for 30 seconds at a time).

And even if it’s not technically part of the OS, will Windows even be in a useable state without it? Most things I see call it a “Core part of the OS,” although those are also specific to Windows 10 so if 11 changed it, that’s news to me. I dont see a difference.
