I'm not sure about the quote though - you installed updates ... isn't that the issue you're trying to fix? Or is KB3156241 still rolling back?
Here are a few maintenance tasks - not sure if it will change anything on the issue, but it might show something!
Also please put the C:\Windows\Logs\CBS\CBS.log in a zip folder and attach it here (Wink would also like to see it - instructions on where to upload it for John are on the Reddit page I linked below the fold.
Please do this before Disk Cleanup - that process might ... well clean up the log
Disk cleanup your Windows Drive
Check your Windows Drive for errors
Command Prompt (Admin)
chkdsk c: /f
yes next boot and then restart to actually let it run
If you have an SSD, skip this step.
Defrag your Windows Drive
Command Prompt (Admin)
defrag c: /x
defrag c: /u /v
I'd also like to see your Disk Management.
Step 1: Download this zip file (contains dmDskmgr-vd.mmc)
Step 2: Double click dmDskmgr-vd.zip to open the compressed folder
Double click dmDskmgr-vd.mmc to launch the custom Disk Management console
You'll get an output similar to this:
Press Alt+PrtScn to grab a snapshot of just the Disk Management window
Open Paint and Ctrl+V to paste it, then save the image
Attach the image to a new post.
Option 2: Use Disk Management in the x-Menu (right click the Windows logo, select Disk Management)
Select View > Bottom > Disk list
Maximize the window and grab the screen shot.
Those are things I would do on my machine to investigate the issue. I'll look at the CBS log and review the disk management.
That's about all I have - read the next steps below the fold. Please post back what you find working with Wink and the other Reddit participants.
John Wnkk suggests hiding the KB3156421 update using the show/hide tool
I think we've done as much as we can here and it's probably best that you work with Wink and his MS team.
I'm playing the middleman anyway - stuff I find over there, plus what I believe might help (Dism & SFC), were used in this thread.
The issue as it is definitely in the domain of MS to fix. Wink further suggest that people experiencing the issue work directly with him on the Reddit page here: KB3156421 - Spinning dots after installing the update, computer either hangs or uninstalls the update : Windows10
When you install the latest Cumulative Update, your computer will want to reboot. Usually it will reboot correctly and finish installing the update, but once in a while we see a situation where the installation doesn’t finish correctly. One of two things may happen:
The update fails and rolls back (uninstalls)
There are actually several different potential causes for this. Some of these are temporary (i.e. the update will install successfully on a later attempt) and some are not.
If the update installation fails and rolls back, I’d like to see your CBS logs to try to determine why this happened. I’d appreciate if you could add all of the files in C:\Windows\Logs\CBS to a ZIP file, name the ZIP file the same as your handle here on the forum, and upload the ZIP file to my OneDrive
We’ll look at the logs and try to figure out what’s happening.
The update fails and your computer hangs on reboot
We have hopefully solved this problem, but it may still occur in some computers. If this happens, I’d definitely like to see your CBS logs as described above. To get out of this situation, you need to reboot your computer in Safe Mode, uninstall the update and use the Windows Update Troubleshooter to hide the update so that it doesn’t try to reinstall itself and put you back in the same bad state.
