This script is launched on a network host by scenario1.vbs. Install.vbs runs locally on the host on which SP2 is to be installed, performing the following tasks:

  • Runs SP2 setup from a remote server.

  • Sets AutoAdmin and RunOnce registry entries on host.

  • Logs results to a text file, computername-sp2-instlog.txt, and copies the file back to administrative workstation.

  • Forces a reboot, after which runonce.vbs is automatically launched.

In the basic scenario, the SP 2 setup file is on a remote server accessible to all network hosts on the list. To run a variation of the scenario in which the SP 2 setup is copied to local hosts and run from there, rename this script to another name (such as install-remote.vbs) and then rename install-local.vbs to install.vbs. You must also make minor changes in scenario1.vbs and the new install.vbs documented in those scripts.

Further explanation of Scenario 1 and the role of each script is contained in the introduction to these scripts at:


Install.vbs corresponds and adds functionality to install.cmd, one of the scripts that ships with Application Compatibility Testing and Mitigation Guide for Windows XP Service Pack 2 and which are documented in the Appendix. You can download a Windows Installer (.msi) file that installs the Guide and its associated scripts from:


To use the script, copy the code, paste it into Notepad, and then save the script as install.vbs. The script is designed to be run automatically as part of the process initiated by scenario1.vbs.

Script Code

'Author: Peter Costantini, the Microsoft Scripting Guys
'Date: 9/1/04
'Must be deployed to a client and launched remotely by scenario1.vbs.
'Assumes that runonce.vbs is in same directory as script.
'Assumes that Windows XP Service Pack 2 setup program is on a remote server
'and runonce.vbs are in same directory as script.
'1. Runs Service Pack 2 setup program from remote server to install
'   Windows XP Service Pack 2. This could take one or two hours.
'2. Configures the AutoAdmin and RunOnce registry settings necessary
'   to run runonce.vbs.
'3. Logs results to text file, <computername>-sp2-instlog.txt and copies
'   the file back to admin workstation.
'4. Forces a reboot of the local machine so that the AutoAdmin and RunOnce 
'   registry settings take effect.
