Using the "Local Group Policy Editor", it is possible to add the execution of a Powershell script at Windows shutdown. As this operation is performed with the "system" account, some operations have to be performed depending on the method chosen (opa0, rsh or ssh).
| Warning |

Please note shutdown scripts are executed when the shutdown is executed either from the "Windows Start" menu or using the shutdown command line. They are not always executed when clicking on the "Restart" button from the Windows Update tool. |
opa0 mode preparation
If the combination of username/password is used, there is no need for configuration change.
If an encrypted file is used to store the password using the "cryptedpsys" parameter, it must be created on a session as "system" account.
To do so, open a cmd.exe window as Administrator and run the following command:
C:\WINDOWS\system32>C:\Charon\psexec.exe -i -s cmd.exe |
A new window will popup. To check you're connected as "system", run:

Execute the same operations as described in chapter "Using rsh" for Tru64 or VMS to enable remote connection for the "SYSTEM" user.
This is case sensitive so for Tru64, specify "SYSTEM" and not "system" in the .rhosts file
It is highly recommended to test the execution of the script in check mode while connected as "system" account. To do so, use the psexec.exe program file provided in the kit or download it from the Microsoft Sysinternals page.
