On August 2, Microsoft will release the Windows 10 Anniversary Update, and not just for PCs, but for phones too. A version will also be made available for the Xbox One, as well as other devices running the OS.
With the release date now less than a month away, Microsoft has rolled out a new SDK Preview, which was predicted earlier today by Gustave M (@gus33000), and first spotted after its release by WalkingCat @h0x0d.
Windows 10 Anniversary Update SDK Preview build 14383 is now available to download via the Windows Insider developer site. Its release follows that of Windows 10 Insider Preview build 14383 for PCs and phones today.
Microsoft hasn't yet made a formal announcement about the new SDK Preview, but it generally warns that "if you are working on an application that you need to submit to the store, you should not install the preview." It also says that each SDK Preview build "is a pre-release and cannot be used in a test environment", adding that you should only "install the SDK on your test machine".
Update: Microsoft has now announced details of SDK Preview build 14383. The new preview "contains bug fixes and under development changes to the API surface area". Microsoft adds that it should be downloaded from the developer section on its Windows Insider site.
