gpg --list-secret-keys --keyid-format=long

Download

Go to https://store.rg-adguard.net.
Search for the HEVC Video Extensions from Device Manufacturer (Microsoft.HEVCVideoExtension) app by entering the following store URL.
```
https://www.microsoft.com/en-us/p/hevc-video-extensions-from-device-manufacturer/9n4wgh0z6vhq
```
- Do not use the normal HEVC Video Extensions app URL, because that can't play HEVC videos in Windows Media Player for some inscrutable reason.
Download the AppxBundle file.
- You may have to right click › Save Link As because the URL scheme is http, not https, if your browser is set to enforce HTTPS-only mode.

If it tries to save as a filename that's just a GUID, you may copy the correct .AppxBundle filename and save it as that instead.
