One would imagine that the Windows Vista setup is smart enough to determine the type of machine that it is being run upon (Tablet PC, Laptop, Desktop etc) and install the appropriate components only. However, that is not the case. On a default desktop install, Windows Vista installs the Tablet PC components, which creates unnecessary services and results in a performance hit.

The Tablet PC bits can be removed through the following steps:

1. Click on start and select control panel.
2. Click on 'Uninstall a program' under Programs.
3. Click on 'Turn Windows features on or off' and scroll down the list of features.
4. Locate 'Tablet PC optional components' and if it is checked, uncheck it. Click on OK.
5. You will probably be prompted for a system restart following this.

This should get rid of a few processes and boost system performace marginally.
