4. In the right pane, right-click OOBETimer, and then click Modify.
5. Change at least one digit of this value to deactivate Windows. This is key, modify the first one to AA, make sure you know what it was originally – you will need it in for step 12. Leave regedit open.

11. Return to regedit. In the left pane, locate and then click the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\Current Version\WPAEvents. If not currently open.
