We had ALL WINDOWS DEVICES (incl servers) mistakenly patched yesterday because there were 2 patch schedules with zero devices in the device box and zero device labels selected. These schedules were there before upgrading to 8.1.108 and no issues. This could be a bug in the code. You should have a warning pop-up or other warning text that you are patching all windows devices in your environment (or similar).
Luckily we had few calls to IT service desk and no production issues.
Add a warning please.
