Windows 10: Miracast no longer working after Servicing Stack 10.0.19041.860 installation!!

I am not able to connect to my 2 Roku Streaming Stick devices. This worked without issue prior to the installation of Servicing Stack 10.0.19041.860 on 2021-03-13.

I have tried everything I can think of to trouble shoot this issue, without success.

I am unable to uninstall this Service Stack to verify if that is indeed the issue!

Any suggestions or assistance would be appreciated. Thanks.

Miracast not Working

Hi Albert,

There's a possibility that an automatic may have occurred or there could be changes performed on your computer that have caused your Miracast to stop working. The device driver currently installed may no longer be compatible.

For us to isolate and address this problem, we suggest updating the Miracast drivers. Please see

Update drivers in Windows 10 for the steps.

Let us know if you need further help.

Regards.

 

Does Miracast support 4K?

Hello,

We suggest that you check with the manufacturer of the 4k display device that you are using if it is certified to work with Miracast. If your display device is certified to work with Miracast, then check if your PC device supports Miracast. You may do so
by following the steps below:

• Click Start, then go to Settings >
  Projecting to this PC.
• Check if your device supports Miracast.

Regards.

 

Printers and Servicing Stack Update

On WIndows8.1 Notepad would suddenly hang and not list any printers. The next day an update came out called Servicing Stack and miraculously Notepad could now find printers. Today(10/9/19) a single update came out(you guessed it) KB4521864 Servicing Stack
and now Notepad can no longer find printers. What's going on?

Also, I tried to delete/remove KB4521864 Servicing Stack and found I could not do that. It says on the installed updates tab that I am supposed to be able to do that by clicking on the installed update and select uninstall or change but that does nothing.
I guess Windows 8.1 is still in Beta.
