Despite its rugged custom processor and long range, one of the Surface Pro X’s short boards is the software ecosystem. Existing Microsoft simulation technology for Windows 10 on ARM does not support 64-bit x86 applications, so that devices such as Pro X cannot run a variety of mainstream applications. But, citing foreign media NeoWin, Microsoft is working to resolve the compatibility issue. Microsoft plans to have Windows 10 on ARM support running x64 applications in an update to windows 10 21H1 (released in the first half of 2021).
“It has been confirmed from multiple sources that the x64 application simulator is being introduced to the Windows 10 on ARM platform within Microsoft,” the report reads. It’s not clear when it will go live, but the odds are that Windows 10 21H1, which will be open to the public in the first half of 2021, will be tested by Windows Insider next year. “
Neither Microsoft nor Qualcomm has commented on x64 application simulations on Windows 10 on ARM 10, and there are still many issues, including performance. For example, when an older version of both 32-bit and 64-bit versions is available, which version will be downloaded on ARM PC Windows 10? Until more developers recompile their applications for ARM64 architecture, the situation should remain confusing.
