If you have to install Microsoft SQL Server 2000 on Windows 7 you’ll find that Windows Sync Center automatically starts at Windows startup. Opening Sync Center will show that Microsoft SQL Server 2000 has been automatically added and cannot be deleted.

To remove this sync partnership you need to edit the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SyncMgr\Handlers

Find the branch that refers to Microsoft SQL Server and delete it. Sync Center should then not start up again at reboot (unless you have have other Sync Partnerships).
