Computer staged from a SysPrepped image doesn't receive WSUS updates

During the SysPrep /generalize process, SysPrep can't delete the following registry key:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate 

This occurs because SysPrep doesn't have permissions to the following key:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Orchestrator\InstallAtShutdown 

Therefore, the operation fails silently.

To work around this issue, follow these steps on the newly staged system:

1. If it's running, stop the Update Orchestrator Service for Windows Update (UsoSvc) service.
2. If it's running, stop the Windows Update (wuauserv) service.
3. Take ownership of the following registry key, and then grant Administrators Full Control:
   
   HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Orchestrator\InstallAtShutdown
4. Delete the following registry key:
    
   HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate
5. Start the Windows Update service.
