Default Behavior

Uninterruptible Power Supply is a Win32 service. In Windows XP it won't start until the current user starts it. When the Uninterruptible Power Supply service is started, it is running as NT AUTHORITY\LocalService in its own process of ups.exe. If the Uninterruptible Power Supply fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the UPS service has failed to start.

Restore Default Startup Configuration for Uninterruptible Power Supply

1. Select your Windows XP edition and service pack, and then click Download.

The UPS service is using the ups.exe file that is located in the %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows XP installation media.
