There seems no way to close the Task Manager in Windows Vista other than rebooting. Once opened, there is no close button, and right-clicking does nothing. Callum Brown
Normally you can close applications by clicking the cross in the top right hand corner or by pressing Alt and F4. Not having a close button was a bit of a mystery, but a Microsoft Knowledge Base article (http://support.microsoft.com/kb/193050) reveals that Task Manager has a Tiny Footprint Mode. Briefly, double-clicking the top border of the window will bring back the usual controls. This applies in Windows XP as well.
