Windows 10: Windows update stuck at 85%

Windows tried to update my system last night. It ran OK until it got to 85% and then it just stayed there, so I ended up shutting off the machine and restarted and it rolled me back to what I had before.

I have already run the windows update troubleshooter. It said it wanted to delete the previously download files. I said OK and then it said that it fixed something.

I also ran DISM and SFC and DISM said it completed successfully and SFC said it found no problems.

I also checked the Device Manager and there are no flagged devices and Dell says that all my drivers are uptodate.

:)

 

Since 03/03/16 Windows 10 tries to update on startup. Stuck at 85%.

Since 3 days ago my windows 10 has been stuck in an endless update loop and requires a System Restore with a recovery USB to even start up.

It tries to update on reboot and gets stuck at 85%. I have tried SFC /scannow.

I believe this update is the issue and I have also tried some of the steps outlined in this Reddit thread to no avail.

Update (KB3139907) and Cumulative Update (KB3140743) Released : Windows10

 

Win10: windows update stuck at never ending loop ?

When in win10:

• Update&security -> Windows update -> Finding update... .... .... ....

Planning to download the latest Win10.ISO (vers.1803) and manually update:
- Then wait that my ordered new SSD arrives and clone the old HDD to it.
