For packages released before July 2004, you must extract the package contents to determine which installer is used and what version it is.

The following table lists the user rights required by Update.exe.

Group Policy Object Display Name	Required by Update.exe	Description
Back up files and directories	Required	You must have this user right to perform backup operations.
Restore files and directories	Required	You must have this user right to perform restore operations. This user right lets you set any valid user or group security identifier (SID) as the owner of an object.
Manage auditing and security log	Required	You must have this user right to perform many security-related functions, such as controlling and viewing audit messages. This user right identifies its holder as a security operator.
Take ownership of files or other objects	Required	You must have this user right to take ownership of an object without being granted discretionary access. This user right allows for the owner value to be set only to those values that the holder may legitimately assign as the owner of an object.
Shutdown the system	Not required, but preferred	You must have this user right to shut down the computer. Some software updates require that the computer be restarted. If this user right is not available, the software update installation will complete, and the user will have to contact an administrator with that user right to restart the computer, if it is required.
Debug programs	Not required, but preferred	You must have this user right to debug a process. Update.exe versions earlier than 5.4.1.0 may require that administrators have this user right to successfully install software updates. Hotpatching technology, also known as in-memory patching, is scheduled for delivery with Microsoft Windows Server 2003 Service Pack 1 (SP1) and will be available for some updates. You must have the Debug programs user right to use hotpatching.
