Get the latest info on new preview builds of Windows 10 as they roll out from Microsoft. Now updated for Windows 10 Build 19044.1739 for the Release Preview Channel, released on May 23, 2022.
Microsoft never sleeps. In addition to its steady releases of major and minor updates to the current version of Windows 10, the company frequently rolls out public preview builds to members of its Windows Insider Program, allowing them to test out — and even help shape — upcoming features. Windows Insiders can choose to receive preview builds in one of three channels. The Dev Channel is where new features are introduced for initial testing, regardless of which Windows release they’ll eventually end up in. The Beta Channel lets you test more polished features that will be deployed in the next major Windows release. Insiders in the Dev and Beta Channels are now testing Windows 11 builds (see “Windows 11 Insider Previews: What’s in the latest build? ”). The Release Preview Channel typically doesn’t see action until shortly before a new feature update is rolled out; it’s meant for final testing of an upcoming release and is best for those who want the most stable builds. This is the only Insider channel that is currently receiving Windows 10 builds. If you were in the Dev or Beta Channel but your PC doesn’t meet Windows 11 requirements, you have been moved to the Release Preview Channel for Windows 10 builds. Use the links below to find information about recent Windows 10 preview builds:
For each build, we’ve included the date of its release, which Insider channel it was released to, a summary of what’s in the build, and a link to Microsoft’s announcement about it. After that you’ll find summaries of the preview builds that led up to earlier Windows 10 feature updates. The build fixes a wide variety of bugs, including one that failed to display the Application Counters section in the performance reports of the Performance Monitor tool, a memory leak issue that affected Windows systems that are in use 24 hours each day of the week, and one that caused file copying to be slower.

This build has a single change: It fixed a bug that didn’t allow the touch keyboard to be displayed when invoked. Microsoft is releasing only very minor changes to its Windows Feature Experience Packs for now, because it’s testing the process of distributing them.
