Apple gets to take advantage of custom extensions to their Arm processor cores which enhance x86 emulation speed, but Microsoft's emulator can only use standard Arm features and is not nearly as fast. Another point is that when running x86 apps under Windows on Arm under Parallels on M1 Macs, you will be relying on Microsoft's x86 emulator rather than Apple's Rosetta 2. They haven't taken any steps to shut down easy public access to preview versions yet, but they could at any time, and it's definitely not legal.įor a professional who relies on Windows to do their work, it just isn't a good idea to go all-in on Apple Silicon yet. Last month, Microsoft made a public statement to confirm that they do not support or license this. The people who are doing it anyways are creating a Windows Insider account and pretending to own one of those Windows Arm computers in order to download preview (in-development) versions of Windows on Arm. Instead, they exclusively sell it through OEM licensing contracts - it's preloaded on the handful of Windows Arm computers being sold today.

Microsoft does not sell Windows on Arm licenses to end users. While it works, there is no way to do it legally. The problem is that yes, you must install the Arm version of Windows.

You may want to consider cancelling your order if you depend that much on Windows.
