After disabling the Geolocation Service by changing startup type to Disabled, attempts to re-enable it will fail with an error message. As the Geolocation Service can no longer be started, Geolocation will remain disabled on the device and prevent location based functionality from working. To work around this issue, manually delete the following regkey using regedit: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceslfsvcTriggerInfo3.
