Ok so i unplugged my HDD, plugged it on my main PC using adaptor.
Put Instant-Shell exe on the HDD, put it back on Arcade.
Launched Instant-Shell, tried to shell again, same thing with the black screen and stuff, didn't work.
Rebooted and undo the change, same thing black screen.
Used regedit and re-changed the value to explorer.exe EVERYWHERE, current_user, local_machine, hkey_users,..
Booted to windows finally, kinda scared to use the program again now..
What can i do to shell correctly ?
thanks !
