How much resource is it using???
Anyhoo To stop this, run the programme "Synchronise" from your "Start/Programmes/Accessories Menu...
Select setup, and uncheck the synchronisation options, then deselect the option to synchronise your home page. From explorer select Tools/Folder Options/Offline Files: deselect the "Enable Offline Files" option. When you reboot you will find the programme is no longer running by default.
You can also remove optional components from your Windows 2000 installation that are not shown in the Add/Remove Programmes applet.
