How can I get rid of ActiveSync?
If you can’t seem to remove ActiveSync using the the Add/Remove Programs tool, for older versions of ActiveSync (3.6 and prior), you may need to manually remove the software by following these steps:
Delete the ActiveSync icon from the desktop (right click and click Delete or drag the icon to the Recycle Bin).
Delete the Microsoft ActiveSync folder in Windows Explorer (by default, it's located in c:\Program Files).
Edit the registry to uninstall the program: navigate to the following keys and delete them: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Uninstall\Windows CE Services HKEY_LOCAL_MACHINE\Software\Microsoft\Windows CE Services HKEY_USERS\Default\Software\Microsoft\Windows CE Services
Restart the computer.

There's an update that you can download and apply to fix the problem. To find out more and get the update, see KB article 918005.
