Thanks so much. This resolved my issue with update KB4074588 on Windows 10 1709 constantly looping and advising a restart to update. I would restart and it advised it hadn't updated and I needed a restart - nearly gave in after trying all the MS solutions re troubleshooting and installing stand alone none of which worked.

Hi all, this error and the solution are being discussed in the Windows forum. Please use this thread for assistance:

Hope this helps,

would not even try to equate errors with a Feature Update to the various errors with this KB.

I was only using my link to point out some possible supplementary diagnostics (starting with ReportingEvents.log) without having to repeat myself so soon.   Sorry for the confusion.

KB4089848 has caused all kinds of issues, including misleading error codes. I

would not even try to equate errors with a Feature Update to the various errors

with this KB.

> I think the OP error code indicates that there will be something else to find in some of the other diagnostics...
