This feature is in fact supported with Windows 2000 Service Pack 3 or later, Windows XP and Windows Server 2003. This means you do not need to run QChain.exe and you do not need to reboot after installing each hot fix. Note Windows Server 2003 supports hot-fix chaining, whereby you can install multiple hot fixes with a single restart. Unfortunately, you usually are prompted to reboot the computer after installing each, so you often have to work around this by forcing the Windows operating system to install quietly (without warnings and prompts) and not to reboot with the -Q and -Z options (which are available in most hot fixes and updates). If you've installed hot fixes and security updates before, you know that basically all you must do is run them as a program.

For example, the hot fix q348932_W2K3_SP1_ENU.exe tells you this fix is in relation to Microsoft Knowledge Base article 348932 and that it is a post Service Pack 1 fix for the English-language version of Windows Server 2003. Most hot fixes and security updates follow a specific naming syntax. The Microsoft Web site contains links to these two sites, and they are currently located at and, respectively, which addresses are entirely subject to change-Murphy's Law, right? You can find hot fixes and security updates in two places: the Microsoft security Web site and Microsoft Windows Update site.

Although these changes do eventually make their way into service packs, you'll often find that critical fixes must be deployed either to resolve problems you're experiencing or to close security gaps. Hot fixes and security updates to the operating system are made available in between service packs.
