Windows 10: Problem with Update KB5004237

After the installation of the KB5004237 Update, in both of my laptops personal an work, windows stops to recognize a secong hmdi monitor

:)

 

KB5004237 will not install!

Three out of my four computers have installed KB5004237 without any problems - the remaining one stalls at 20%, and throws up error 0x800f081f.
I have run sfc + dism + the update trouble-shooter to no avail.
It would seem that I am missing certain data/ previous update from what I can gather. Is this a known problem? and is there a starting point for me to try.
Windows update suggests that I am up to date.
Any help appreciated - thanks.

Windows 10 1709 System Restore problems...

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
