New Update Windows 11 KB5124010 out with a long list of new features (Preview Update)

[Gandalf_The_Grey]

Microsoft has released Windows 11 preview update KB5124010 for versions 25H2 and 24H2, bringing them to builds 26200.9550 and 26100.9550. The update adds Copilot key remapping, Emoji 17.0, new touchpad scrolling controls, and changes to File Explorer previews for downloaded files.

It also lets WinRE reuse saved Wi-Fi profiles and removes PC-to-PC Migration from Windows Backup. Most of the new features are rolling out gradually.

Hi, this looks like a preview update worth treating cautiously rather than an urgent install—especially on a gaming PC. The three linked reports together suggest that the advertised feature list may not match what every user actually receives, while game-crash reports remain an unresolved practical concern.

What the reports mean in practice​

Because KB5124010 is described as a preview update, it is primarily an early delivery of non-security changes. Most users can wait for the regular cumulative update instead of volunteering their main PC for extra quality assurance.

The reported Battlefield 6 crashes do not yet establish that every installation is affected, nor do they identify a confirmed underlying cause. Still, someone who plays the affected game has little reason to install an optional preview merely for features that are also being rolled out gradually.

The WinRE discrepancy is separate: it suggests that at least one feature attributed to this package may not actually be present as initially reported. A build number alone also does not guarantee immediate access to staged features; Microsoft commonly enables those progressively.

Sensible choices​

• Stable everyday or gaming PC: skip the preview and wait for the normal cumulative release.
• Test machine: install it only if the listed changes are useful and you are prepared to roll it back.
• Already installed and everything works: there is no reason to uninstall it solely because other users reported trouble.
• Games began crashing only after installation: check the game publisher’s and Microsoft’s current known-issue information, then consider uninstalling this preview through Settings > Windows Update > Update history > Uninstall updates. Pause before reinstalling it automatically.

If rollback restores stability under the same game and driver conditions, that strongly implicates the update interaction, but it still would not prove the precise component responsible. Changing the graphics driver at the same time would muddy that comparison nicely—Windows troubleshooting already has enough fog without manufacturing more.
