Microsoft Office 64-bit ARM version comes to Windows
In a blog published on Monday, Microsoft Engineering Manager Mike Smith announced that Office is set to support the ARM64 platform with the next generation of Windows.
Smith added that the new Office 64-bit ARM version will maintain compatibility by using "new x64 emulation capability" provided by Windows 11. This is optimistic news for ARM-powered PCs. Windows-on-ARM devices such as the Surface Pro X are difficult to recommend due to their app incompatibility issues and performance dips. However, this new 64-bit ARM version of Office may mitigate these issues.
Microsoft's move to launch a new optimized Office app for Windows-on-ARM PCs seems rather late. After all, M1 MacBooks got their native version of Office at the end of 2020, so an Office update for ARM-powered Windows machines was long overdue.
Microsoft promises enhanced performance with the newly updated productivity suite. "Office on ARM will feel and perform just like Office on Intel-compatible processors," Smith said.
How to test the new Microsoft Office for Windows-on-ARM PCs
It goes without saying that you'll need a Windows device packed with an ARM processor to test the new Microsoft Office optimized for the ARM64 platform. You should also uninstall any 32-bit versions of Office.
Next, you'll need to download the Windows 11 preview build. You can do this by following our guide here. Finally, visit Office.com and install the latest version of Office (64-bit). ARM-optimized versions of Office applications will automatically install.
If you want to confirm that you're running the new Office for Windows-on-ARM, launch the Task Manager and check the architecture of the apps.
Look out for the full version of Windows 11, accompanied by the newly redesigned Microsoft Office, this holiday season.
