Windows 10 Upgrades Fails with ProfileUnity Client Installed
Since the beginning of Windows 10 in our company I have been stumped by failing Windows 10 Feature Updates... It got the point (after spending 80-120 hours) that our upgrade process for Windows 10 to Windows 10 builds involved formatting the machines and reinstalling all software. Needless to say, this was a major headache. Since the release of 1709 for Semi-Annual Channel, my machine has failed to update multiple times and I decided I would submit myself to the pain and suffering of attempting to resolve it yet again. Windows update would show an error code of 0x80070057. Most of the advice online says to reset windows update, delete SoftwareDistribution, etc. I've tried all of that 100s of times before, so I went to find the setuperr.log file in the hidden directory on C. In that log file I saw a bunch of errors (some below): 2018-01-30 01:11:49, Error CONX 0xd0000034 Failed to add user mode driver [%SystemRoot%\system32\DRIVERS\UMDF\uiccis
