Type : psexec -i -s cmd.exe (i= interactive, s= running as system) 5.Once you hit enter, another command prompt will open that will be running as the system account (NT Authority\System)(to check this type whoami). Leave this command prompt open 5.Start task manager and kill "explorer.exe" 6.Type in the command prompt running as system account : "explorer.exe" 7.Wait for the personalization part to finish.. 8.Enjoy and be carefull not to break something!
