Re: Can't screen mirror from Windows 10 laptop to Roku

For me, to get it to connect the first time I had to follow the steps here. Since doing that, connecting hasn't been a problem: 

(1) Set Roku screen mirroring to "prompt first" (NOT always); (2) RE-BOOT ROKU; (3) Go to PC action center and click connect; (4) NOW your PC will list your Roku device, but it still won't connect until you; (5) Go back to Roku settings and change to "Always."

Re: Can't screen mirror from Windows 10 laptop to Roku Streaming Stick+

The last (third) suggestion on this webpage worked for me!      I have a Roku Ultra and I updated the wireless network driver on my laptop running Windows 10.  I did not see a Network Adapter that said "wireless" so I took an educated guess on Intel Centrino(R) Advanced-N 6235 and it worked after restarting PC.       I hope this helps someone before reading and trying everything I did first!

Re: Can't screen mirror from Windows 10 laptop to Roku

Hi Guys,

The issue looks firewall related for Windows 10. I run Vipre firewall and had to set Trusted Inbound and Trusted Outbound to "Allow" for the file "wudfhost.exe" and I set Public Inbound and Public Outbound to "Block".

Try setting a rule in your Firewall allowing "wudfhost.exe" as above

So what's wudfhost.exe?...according to Comodo: 
"WUDFHost.exe is a legitimate file. This process is known as Windows Driver Foundation – User mode Driver Framework Host Process. It belongs to Windows Operating System and was developed by Microsoft Corporation. It is commonly stored in C:\Program Files. 


I'm running Windows 10 Home 10.0.18363 Build 18383 with all updates. I was having the same issue being unable to screen mirror to Roku devices (I have 2 different Roku TVs and a Roku Ultra) yet being able to cast from say the YouTube app to the Roku devices. could also try below if issue persists:

Temporarily disable Windows Firewall & network protection as attached. 

Disable Domain, Private and Public Network => set to "off"

Connect to your Roku again(Action Center > Connect ...choose your Roku Device and it hopefully connect this time.

Re-enable Domain, Private and Public Network => set to "on"

...if that doesn't work try also disabling any other firewalls you have running Norton/McAffee etc and try connecting again as above.

It's seems to have to train the firewall to accept the Screen Mirror from your Windows 10 PC.
