UPS Service Entries

The Registry does not contain information for the UPS service until you check the Uninterruptible Power Supply Is Installed checkbox in the UPS dialog box and then chooses the OK button. Changes to settings should be made by using the UPS icon in Control Panel.

The UPS service will not start unless the UPS subkey is present in the Registry, all parameters are present in the Registry, and all values are within the correct range. If any of these elements are missing or in error, a message announces that the UPS service is not correctly configured. All corrections can be made using the UPS icon in Control Panel.

The UPS parameters remain in the Registry if you remove UPS. The path for the UPS subkey is the following: 

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UPS
