RTM candidate for Windows 10 Anniversary Update named by internal sources

Right now, the latest build served up in the Windows Insider program is 14383, which was released on Thursday to participants in the Fast Ring. However, according to the latest Windows 10 rumor from “internal sources,” the first Release To Manufacturing (RTM) candidate is Build 14384, a single digit away from the current preview release. That, folks, indicates that Microsoft is finally wrapping up Redstone 1 (RS1) development, aka the Anniversary Update.

Although RS1 development seems to be coming to a close, Windows Insider lead Dona Sarkar indicated on Thursday that the team is still taking fixes for Anniversary Update. She added that her team “scrutinizes” each fix more thoroughly in “Ask Mode,” and that participant feedback is still vital data for all Anniversary Update approvals.

According to the unnamed internal sources, Build 14384 will be the first RTM candidate, and that a final version of RS1 will likely be offered to Insiders by the end of next week. Typically, there’s more than just one RTM candidate brewed up by Microsoft. In fact, multiple builds are generated and then pulled through rigorous internal testing. The version with the least amount of issues will earn the official RTM badge.

Officially, Microsoft no longer uses the “RTM” terminology. That’s because Windows 10 is now a service, meaning the platform will gradually evolve over time rather than the company dumping new versions on the market every three years or so. That applies to huge updates like Anniversary Update as well, although there’s really no other way to describe a mega-update’s development conclusion than by sticking with the old-school RTM terminology.

There’s still time to flood Microsoft with feedback about Anniversary Update before it is scheduled to go public on August 2. After that, Microsoft is expected to switch gears and begin working on Redstone 2 (RS2), which is slated to go public sometime around spring 2017. This mega-update sequel will supposedly begin hitting the Windows Insider program through builds in the 148xx range during the second half of August.

Thus, to find out when Insiders are actually using a build designed for RS2, they will be able to simply look at the build’s version number on screen. For example, Insiders can currently see the RS1 label within the build’s watermark, such as “Build 14379.rs1_release.160627-1607.” That “rs1” portion will likely be exchanged for “rs2”… if Microsoft continues to use the watermark, that is.

“The desktop watermark is now gone. This is because we’re beginning to check in final code in preparation for releasing the Windows 10 Anniversary Update to customers on August 2,” Sarkar said on Thursday regarding the new 14383 build. “It’s feeling like ship season around here and we can’t wait to see what you think of this build.”

From this point on, the Anniversary Update features are locked and loaded, and preview builds will thus focus on improvements and fixes for both PC and mobile. We’re eager to get our hands on the “RTM” build, so stay tuned for news surrounding that highly anticipated release.

Not ready for Windows 11? The Windows 10 November 2021 update is coming
Windows 10 refresh features.

If your PC is one of the many that are unable to officially run Windows 11, then you might want to get ready for the next big Windows 10 Update. Microsoft just announced that it is taking final steps and getting ready to launch the Windows 10 November 2021 Update.

This next version of Windows 10 underwent over five months of testing with Windows Insiders and is now in its final phases. There aren't any big features that come along with it, but Microsoft notes that build 19044.1288 is the final build for the November 2021 Update.

Microsoft warns select Windows 11 beta testers to move back to Windows 10 now

Microsoft is sending a warning out to those who managed to beta test Windows 11 on unsupported hardware. It is now time to go back to Windows 10, as your device is no longer eligible to join the Windows Insider program on Windows 11.

While the message might seem shocking, it is actually a long time in the making. When Microsoft first announced Windows 11 in June, they had allowed all Windows Insiders who were already testing previous Windows 10 builds to beta test the operating system. It was intended as a "limited exception" thank-you gift to the Windows fans, but now that an official October 5 Windows 11 release date has been announced, Microsoft is ready to move on.

Microsoft is making it easier to help you determine if you can run the Windows 11 operating system on your existing PC.  Soon, Windows Update in Windows 10 will show a notification prompt about your system's compatibility with the next-generation operating system.

Spotted by Windows Latest, the newest Windows 10 Insider preview build now has some in-app messaging about Windows 11 in Windows Update. This build is a preview of the incoming Windows 10 21H2 Update, so the feature is just in beta for now. Presumably, this messaging will be more permanent and will roll out to everyone later this year once the 21H2 update is finalized this fall.
