I also have this problem. There is further concern because this problem causes windows update not to check for further updates - I know there are more because I reinstall regularly
That's very interesting to hear because I to had an update issue back on the 17th June. I was pointing the finger at the disk clean utility and in the end I posted over on TechNet and was offered a fix (post #2) that worked correctly.
Sorry for not replying sooner, Mooly - I had a knee replacement last week, am on pain pills and not too sane at this point. However, I had problems with KB2976978 this week installing over and over and over again on my desktop. I finally just "hid" it so Windows Update couldn't find it each time it searched even tho I had not installed it. Screenshot attached of the hidden update - 25mb -hope this helps you.
I just checked my Win8.1 Pro and KB2976978 installed on 6/9/2015, haven't had it offered since.
Yup I received another on and installed, again it was a different size:
It's getting me ready for Windows 10.This update performs diagnostics on the Windows systems that participate in the Windows Customer Experience Improvement Program in order to determine whether compatibility issues may be encountered when the latest Windows operating system is installed. This update will help Microsoft and its partners ensure compatibility for customers who are seeking to install the latest Windows operating system.
Hi John, hope the knee settles down... it will be worth it in the end I'm sure.
For curiosity I rolled back to 7th June image and let Windows Update do its thing again. As before, the same two updates are offered. I installed them, ran a disk clean, reboots and so on, and...... no more offerings ! I forced an update check and again, nothing there.
Methinks MS are making all this up as they go along.
My "hidden " update has now disappeared from the hidden list and no further problems showing - think you are correct Mooly , they are making this up as they go. It's probably sorting itself out but not fast enough for those of us who like a little "order" in our life - lol.
I had installed KB2976978 yesterday and WU offered it again. I ignored the 2nd offering and when WU ran this afternoon it disappeared so all is good.
