I installed Cyberpower’s program to shut down my Windows 8.1 computer (an Intel Compute Stick) when the utility power fails and the Cyberpower UPS has run for 5 minutes. Unfortunately, I can no longer shut down my Intel Compute Stick running Windows 8.1 by using Shut Down in Windows. Shutdown no longer switches off the Intel Compute Stick. I get a message from Windows showing that Windows is shutting down but the power light on the Intel Compute Stick remains on. I have to power down the Intel Compute Stick by pressing the physical power button.
I have uninstalled the Cyberpower program but the problem remains. I have run CCleaner and there are no registry errors and all unneeded files have been deleted.
Can anyone recommend a third-party uninstaller, in case there are files, such as a driver file for the UPS, left behind?
No trace of Cyberpower’s program shows up in Ccleaner’s Uninstall function and nothing shows up in Windows 8.1’s Task Manager in Startup.
