I’m really struggling with my clients having Windows Update failures, particularly with the October Security rollup (KB3185330), but also KB3133977 in some cases.
— My Dell Optiplex 780 and 790 models are affected for sure, as I’m hearing from my clients and working with my test computers. (Also, Dell Inspiron 15-3537 in one case)
— My test computers have no hidden updates and have all other Windows Update up-to-date.
— My test computers have no antivirus.
— When the KB3185330 is run and I restart, it goes to 79% complete in configuring, then it goes to:
Failure configuring Windows updates, Reverting changes. Do not turn off your computer.
— Something this leads to hours and hours of hard drive writing, even to the point of filling the drive (in the (C:\Windows\logs\CBS folder).
— I’ve run the Microsoft System Readiness Tool (32-bit link, 64-bit link), which seems to check the integrity of some of the Windows Update folders. It leaves a CheckSUR.log file in the C:\Windows\logs\CBS folder. Whether it comes back clean or fixes something, it doesn’t prevent the October security rollup from failing.
— I made sure drivers were all up-to-date.
— I tried disabling from unnecessary devices (Intel Active Mgmt SOL, COM1, LPT1), no success.
— I tried changing the drive boot from AHCI to Legacy, no success.
If others are struggling with this, especially techs, please post below — no login necessary. Let’s figure this out or get Microsoft to pull it and fix it.
