Microsoft has released a new Xbox console update, OS version 10.0.26100.8866. July 2026 update brings all sorts of new features and improvements, including longer gamertags, new library and profile customization options, and a handful of quality-of-life additions across Home, the Accessories app, and cloud gaming. The new update started rolling out to gamers yesterday.
Here's the full changelog of the update:
Gamertag changes
We’ve heard from players who wanted a little more flexibility when choosing a gamertag, and we’re bringing back support for unique gamertags up to 15 characters long, expanded from the previous 12-character limit.
This update applies to gamertags that are unique and available, giving you more room to create a gamertag that feels like you. Gamertags that are not unique or contain non-Latin characters may have a suffix and will continue to support up to 12 characters.
