Disable the ActiveSync Partnership setup dialog

If you are developing for windows mobile devices and got several devices, you may not want to be asked to setup a “New Partnership” on a new connected device.

To avoid partnering, you use a registry key and you will no more be asked to setup a partnership with your PocketPC or Windows CE device.

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services]"GuestOnly"=dword:00000001

To switch back to accepting partnerships, use this

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services]
"GuestOnly"=dword:00000000

If you need to set options in activesysnc you cant do, if you did not setup a partnership or if guest-only is enabled.
