So far I can't rind definitive proof, but we are having an issue with computers renaming themselves to WIN10- after running Windows 10 cumulative updates. 1703, 1709, 1803 etc. It doesn't seem to happen to computers were we installed Windows 10 from scratch. The only common denominator I can see is that these machines were imaged using Dell Image assist. Anyone else experience this problem? I was thinking maybe it had something to do with Sysprep since these updates seem to take the place of future versions of Windows.
