I have is Windows 11 Enterprise, and that doesn't start the classic... even if I manually invoke that classic notepad.exe from system32.
I have never opened Microsoft Store other than to install WSL2, and I don't think my company's admins are dumb enough to provision such stuff automatically, but I dunno. If I uninstall the store Notepad, it'd probably revert back to the classic version, but of course I'd rather uninstall the entire OS...
I hope her reports continued to "take an entire day".
