And it’s definitely not a hit when it comes to features. Windows 10 build 20201 is just a bundle of fixes and improvements, but there’s always room for releases like this.
This newest version of the preview comes 5 days after the last one arrived.
Build 20201 is from the Iron development branch, and part of rs_prerelease, meaning it is not tied to a specific feature update. You might have expected that these new features Microsoft has been development would show up in 21H1, but there is little chance of that now that it may be canceled.
In any case, the Windows development chugs alone on its own path.
As for what got fixed and improved with build 20201, there is quite a bit here.
For starters, Redmond has taken care of an issue where some Microsoft Store games that were protected by the Easy Anti-Cheat solution failed to launch. Some of these titles may still have the need of an update to fully resolve the issue, but Microsoft has done what it could from its end.
The company also took care of an issue where the minimize, maximize, and close buttons were stuck in their original position after resizing a UWP app.
A few other things also got a look.
In terms of known issues, there are a bunch here. Including, sadly, reports of the update process hanging for extended periods of time when attempting to install a new build, and some Office applications crashing or missing after updating to a new build.
Do give the full list a read before deploying this version.
You can grab this newest release via Windows Update, as long as you are enrolled in the Dev channel of the Windows Insider Program. It is also possible to sign up for it from there.
