Microsoft just rolled out the Creators Update for Windows 10 PCs and, as expected, the release has caused a couple of bugs. One of them affects the performance and health of UPS-connected desktops.

A Windows 10 user who just upgraded to the Creators Update posted the following complaint on the Microsoft Community page:

I’ve upgraded to Creators Update this week. One bugging issue: desktop computer connected to UPS (APC, HID battery, native Win driver). Device Performance and Health complains about battery life being affected by screen brightness being set to maximum. Obviously I cannot change it (HTPC with NVIDIA ION, connected to HDMI TV) – in settings there’s no such setting available.

The warning states:

The screen brightness on this device is currently set at maximum. This can impact your device battery life. You can change this in Setting.

Now there’s the rub: it is impossible to adjust the screen brightness on a desktop. Another user reports the same problem even after changing the screen brightness:

I’m on a laptop and even after lowering screen brightness, the warning doesn’t go away.

The good news is that a Microsoft representative vowed to escalate the issue with the Redmond giant’s engineers. Hopefully, Microsoft will soon roll out a hotfix to patch this problem.

If you’ve also experienced various issues on UPS-connected desktops after upgrading to Windows 10 Creators Update, use the Feedback Hub app to provide Microsoft’s engineers with more details about this problem.
