1.6.3.5 Installing Multiple Hotfixes 
When a large number of hotfixes have been released, especially critical security updates, you might find it 
inconvenient to install multiple hotfixes at each computer in the network, especially when a reboot is 
required after each installation. You can use Qchain.exe or a batch file to simplify this process and install 
several hotfixes at once. 
• The Qchain.exe utility configures the computer after you install several hotfixes so that a single reboot 
can correctly install all the hotfixes. You can obtain Qchain.exe from the 
http://support.microsoft.com/
 
Web site by searching for Knowledge Base article #Q296861. To use Qchain.exe, first run the .exe file 
for each hotfix. Then use the 
-z
 option to prevent the hotfix from rebooting the computer after 
installation. 
• You can combine several hotfixes and the Qchain.exe program, if necessary, into a batch file to install 
multiple hotfixes in a single operation. Use the 
-m
 option with each hotfix .exe file to suppress its output, 
along with the 
-z
 option to prevent rebooting. If Qchain.exe is required, include it as the last command 
in the batch file.
