Earlier today, Microsoft released Windows 10 Insider Preview build 21286, introducing a few new features. One of them is a new news feed that sits right in your taskbar. Now, you won't have to launch a browser or app to get to weather, news, sports scores, and more. It's similar to what Cortana used to offer.
Alongside the new build, there are new ISOs, something that we haven't seen since the switch to 21xxx builds. The last publicly available Windows 10 Insider Preview ISO was build 20231, which was released in early October. As usual, there are options to download Windows 10, Windows 10 Enterprise, and Windows 10 Home China.
Interestingly, there's still no Windows 10 SDK Preview since the switch to build 21xxx and the return to the rs_prerelease branch. There's nothing new from Windows Server either.
There is, however, a new Windows 10 Client ARM64 Insider Preview VHDX image. This is made for those using Hyper-V with Windows on ARM. While the new builds do include cool new features like x64 emulation that you might prefer to test in a virtual machine, Hyper-V still hasn't shipped for Windows on ARM. You need build 19559 or higher for that.
