Microsoft today released Windows 10 Insider Preview build 21277, with one of the big features being x64 emulation for ARM PCs. It also comes with a bunch of fixes and known issues.
Today, Microsoft released not one but two new Windows 10 Insider Preview builds to the Dev channel. One of them is from the fe_release branch, while the other is a return to rs_prerelease.
With today's Windows Insider Preview build in the Dev channel, Windows on ARM users can now run emulated x64 apps, opening the door to a much wider range to app compatibility, such as Adobe CC.
