XBox One S update

this is an update for the xbox one s by the way

To take advantage of 120Hz, you'll need an Xbox One X or Xbox
One S running the Xbox May 2018 Update. So as far as the original Xbox One it sadly is not a possibility.

Yes, it is likely that your Xbox One will not be compatible with the new Forza Motorsport dashboard update or with game updates in general, as Microsoft is focused on the new generation of consoles, the Xbox Series X and S. The Xbox One is no longer being updated and Microsoft has already announced that it will end support for the Xbox One, but has not yet said when.

Elaboration:

Xbox One at the end of its cycle:

Microsoft is increasingly focused on the new generation of consoles (Xbox Series X and S) and, therefore, support and updates for the Xbox One are being reduced.

New dashboard update:

It is likely that the new Forza Motorsport dashboard update, or other game updates, will not be compatible with the Xbox One.

Focus on the next generation:

Microsoft has already announced that it will end support for the Xbox One, and its attention is directed to the Xbox Series X and S, the most recent generation.

System updates:

Your Xbox One may no longer be receiving system updates, or the updates you do receive are only to ensure the security of your console.

Btw this is the 1.16.1 update 4 Xbox one s

Hi,

What game or games does this message pop for? Many Xbox One games have updates specifically for the Xbox X. If your Xbox One game has a 4K assets update for example, you'll be prompted to download this when using the drive on the Xbox One X console.

The Xbox One S and original Xbox One don't support X-enhancements, so you won't be prompted for that update when using the drive on the One S.

Please look at the
following link, it explains how to update games for Xbox One X enhancements, while still using a Xbox One S or original Xbox One.
