Quick Hands-On with Windows 10X Emulator Build 19578

Posted on March 11, 2020 by Paul Thurrott in Windows 10X with 12 Comments

This week, Microsoft released a much-improved version of its Windows 10X emulator. Now, anyone can try it out—well, assuming you have Windows 10 Pro, as you need Hyper-V. But it’s still horribly slow and incredibly buggy, making it impossible to accurately assess the system’s ability to run legacy desktop apps.

That said, it is much improved. With the previous emulator image, I was unable to sign-in to my Microsoft account, but I did sign-in via an app and get my Microsoft account propagated throughout the OS and into the Edge web browser. That provides a slightly more customized experience, which is nice, but it also gives me a better idea of how this thing compares to what Microsoft is now calling Windows 10 desktop. For example, I can now access my recent documents right from the new Start.

What I’d really like to do, of course, is use Windows 10X in a standard landscape single-screen configuration. But when I try to select that, the emulator balks. In lieu of that, here are a few quick observations.

A new UWP File Explorer app is provided instead of the old-school desktop version.

Desktop applications get the standard three window buttons—Minimize, Maximize/Restore, and Close—but I couldn’t get Notepad to run in a floating window.

UWP applications—and, curiously, the new Edge—have only two window buttons, Minimize and Close.

I could, however, get Notepad to span both screens. Which is silly, but makes sense.

More soon.

    Are you sure floating apps are going to be supported in this initial version of 10X?

    Regarding the requirements for the emulator, having Hyper-v installed and working isn't enough: you actually have to have CPU made by Intel. AMD's Ryzen/Threadripper won't work (for now). The emulator's release notes also mention this but I somehow missed this and was left wondering why I wasn't able to run the thing, even though Hyper-v is happily up and running on the same system. This is from the docs: AMD processors are not supported at this time. Nested virtualization is required to run Windows 10X in the emulator and Windows does not yet support this on AMD processors. Stay tuned!

    This has something to do with Hyper-v's nested virtualization feature only supporting Intel CPU's. Here's the UserVoice regarding this: https://windowsserver.uservoice.com/forums/295047-general-feedback/suggestions/31734808-nested-virtualization-for-amd-epyc-and-ryzen
