Microsoft has announced that, with the release of Windows 11, Microsoft Office will have a native 64-bit Arm version for devices like the Surface Pro X.

This version of Office Tab is free for non-commercial, personaluse, and works only with Word, Excel, and PowerPoint.

I’m using Microsoft 365 desktop on a Windows 10 64-bit system, but you can use older versions through PowerPoint 2007. However, PowerPoint for the web won’t support this technique.
