Some Microsoft software updates use Update.exe as the Setup program. Update.exe version 220.127.116.11 and later versions require that the user who installs the software update is an administrator with certain user rights. This article lists those user rights requirements. If a user does not have the required user rights and tries to install a software update package that uses Update.exe, they may receive the following error message:
You do not have permission to update <OS name>. Please contact your system administrator.
If the software update installation was performed in unattended mode by specifying either the /quiet or /passive command-line switches, this error message is displayed in the installation log. By default, the installation log is located at %systemroot%/KB######.log, where ###### is the number of the Microsoft Knowledge Base article for the fix that was applied.
To determine whether a software update uses Update.exe as the Setup program for packages released after July 2004, examine the Installer Engine value on the Version tab of the Properties dialog box for the software update package. 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
Back up files and directories
You must have this user right to perform backup operations.
Restore files and directories
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
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
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
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.
You must have this user right to debug a process. Update.exe versions earlier than 18.104.22.168 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.For additional information about patch and update management, visit the following Microsoft Web site: http://technet.microsoft.com/en-us/library/cc768045.aspx
