For mainstream support x64 on ARM64 is coming with Windows 11 -
ARM64 Office is available for those running Insider Windows 11 and Insider Office -
64-Bit Office for Windows on ARM
I'm running both on my Surface Pro X as of yesterday.
Thanks for posting those Jeffery! After reading through those blog posts I'm now pretty excited about Windows 11 on ARM, and have just about convinced myself to enroll in the insider program and switch my Pro X to the dev channel to try it out. Now that it's been a few days have you had any show-stopping issues with yours? I don't know if you were running a Windows 10 build that had x64 emulation prior upgrading, but if so, have you seen any improvements in that going from 10 to 11, if you don't mind my asking.
I've been in the Insider Dev Channel since the beginning (2014) - My Pro X has been running it since I received it. I didn't run into any issues under the old emulation (other than battery life). In my use case I haven't seen much difference.
Awesome, thank you for the feedback!
