Problemi di supporto HEVC in Windows 11

As of 2025, Windows 11 does not include native support for the HEVC (H.265) codec out of the box due to licensing and royalty considerations. To play or edit HEVC videos on Windows 11, users typically need to install the HEVC Video Extensions available from the Microsoft Store, which usually costs $0.99. This official extension enables HEVC playback in Windows built-in apps like Media Player, Photos, and others and utilizes hardware acceleration on compatible devices for better performance ^{[1] [2]}.

There is also an unofficial free method by installing the HEVC Video Extensions for Device Manufacturers, which was originally provided to OEMs and can be installed manually via a downloaded app package and PowerShell command. However, this version may not be fully reliable on all devices or with recent Media Player versions ^[2].

Alternatively, users can rely on third-party codec packs such as the K-Lite Codec Pack that include HEVC support, but caution is advised as some codecs packs might cause conflicts or include unwanted software ^[1].

When built-in support or extensions fail, transcoding HEVC videos to more widely supported codecs like H.264 using software such as VideoProc Converter AI is recommended. This software allows batch transcoding with hardware acceleration and maintains high visual quality, facilitating playback and editing on Windows 11 ^[1].

In summary, for official and stable HEVC playback on Windows 11 in 2025:

• The paid HEVC Video Extensions from Microsoft Store ($0.99) remain the primary supported method.
• A manual install of the free OEM HEVC codec extension is possible but less reliable.
• Third-party codec packs like K-Lite can provide HEVC playback but should be used cautiously.
• Transcoding HEVC to H.264 with specialized software is a practical workaround if playback issues persist.

This situation continues due to licensing fees that Microsoft manages by offering HEVC support as a separate paid extension rather than integrating it directly into Windows 11 ^{[1] [2]}.
