The next big update to Windows 10 is nearly upon us: Windows 10 version 1703, known as the Creators Update, will be published to Windows Update next Patch Tuesday, on April 11th.
The final build is—probably—15063. That build is already available to insiders and should soon become available for the Windows 10 Media Creation tool, but we also know that there are going to be some patches materializing some time between now and then. There's a small chance those patches will bump the build number; more likely, they will instead bump the patch number, which is currently a pristine and perfect 0 on the desktop. The mobile build has already been bumped, to 15063.2, to handle an installation problem when upgrading from version 1607.
The article brought up a good point on insider builds to flush out bugs.
My experience with the integrated Beam support did, however, bring up some issues that call to mind my broader concerns about how Windows 10 is tested. The Windows Insider program is huge, with Microsoft now claiming more than 10 million testers, but my suspicion is that few of these testers are using the previews on their daily driver PCs, because their quality simply isn't good enough. Rather, they're using the previews in virtual machines or on secondary systems. As such, the previews get relatively little use on systems that have lots of hardware—as became apparent with version 1607's handling of webcams—or a wide range of software.
