This is a fundamental change that will affect device detection as you know it

Chrome 110, due for release on 1 February 2023, will be the first Chrome version that has information removed from the mobile and tablet User-Agents. In essence, you will not be able to tell the difference between different mobile or tablet device models.

Windows 11 is only detectable with User-Agent Client Hints

We’re disappointed that Microsoft communicated their sudden change so poorly

In a surprise decision by Microsoft, Windows 11 does not have an associated User-Agent string and can only be detected with User-Agent Client Hints. It’s interesting that Microsoft has decided to implement an experimental feature that has yet to go through the Web standards process.
