How annoying is it that MS automatically assigns your User Folder name as the first 5 letters of your Account (or email) name? To try to take control of my User Folder name (c:>Users>[Folder Name]) I dutifully Created a Restore Point then followed MS’s instructions to change my User Folder name (not my Account name). Kapow, Windows 11 pooched. Could not get to System Restore. Booted into Safe Mode, Advanced Options etc, ended up in a Do-Loop (a fun computer amusement park ride which those of you like me who grew up with Fortran would recognize). BIOS (Dell) did not have Factory Reset as an option! I tried all the other usual options to no avail. Eventually I was able to boot into a busted version of Windows (taskbar missing so no way to start System Restore.) What finally worked? Task Manager->File->Run New Task->restrui.exe
Whew
