How can I uninstall hidden Windows components?

A. When you start the Add/Remove Programs Control Panel applet and select Add/Remove Windows components, the system doesn't display all of the components because Windows doesn't want them uninstalled. However, you can change which components the system displays. Perform the following steps:

  1. Open the sysoc.inf file located in the %systemroot%\inf folder.
  2. Go to the \[Components\] section.
  3. Locate the entry you want to make uninstallable and remove the word "hide." For example, for MSN Messenger Service, change the line
  4. Save the sysoc.inf file.
