Add Miracast Support to Windows 10 LTSC

Have you ever found yourself in a situation where you needed to cast your display to a Windows 10 LTSC 2021 device, only to discover that Miracast support was missing out of the box? I can relate. It can be frustrating to encounter such limitations. However, fear not! I delved deep on internet and have emerged with this comprehensive guide that will assist anyone facing a similar predicament.

For those who don’t know, Miracast is a wireless display standard developed by the Wi-Fi Alliance. It allows users to mirror the screen of a compatible device, such as a smartphone, tablet, or PC, onto a larger display, such as a TV or monitor. With Miracast, you can effortlessly share photos, videos, presentations, and more without the need for cables or additional hardware.

The reason Miracast doesn’t work out of the box is due to missing packages in the Windows Installation. Fortunately, there’s a way to resolve this issue and install these missing packages.

Please note that the following steps assume you have the en-US edition of the system. If you have a different language pack, make sure to replace the LanguagePack (3.zip) file with the appropriate one for your PC.

Steps to Enable Miracast:

1. Download the zip packages: MiraCast Support Files. If you prefer, you can also download the original files and use software like 7zip to extract the ESD files. For your convenience, I have zipped the extracted files together.

2. Extract the 1.zip, 2.zip and 3.zip in their respective folders.

3. Start the CMD/Powershell from the base folder, ie the folder under which these files were extracted.

4. Run the following commands:

    dism /online /Add-Package /PackagePath:1\Microsoft-Windows-RegulatedPackages-Package~31bf3856ad364e35~amd64~~10.0.19041.1.mum
   

    dism /online /Add-Package /PackagePath:2\Microsoft-Windows-RegulatedPackages-wow64-package~31bf3856ad364e35~amd64~~10.0.19041.1.mum
   

    dism /online /Add-Package /PackagePath:3\update.mum
   

5. Restart your device.

6. Open the Settings app and go to “App & features” and then “Optional Features.”

7. Click on “Add a Feature” and search for “Wireless Display.”

8. Install the feature.

That’s it! Wireless Display should now be enabled and ready to use on your device.
