What you need to know

  • Microsoft Teams for ARM64 is apparently live.
  • This new version is optimized to run natively on Windows on ARM PCs.
  • We have confirmed it runs as 64-bit on Surface Pro X.

It was only yesterday that Microsoft announced that its Microsoft Teams app was nearly ready to get an ARM64 compiled version for Snapdragon-based PCs. Today, a working version has been found on Microsoft's website for download.

First noticed on reddit, the app lives under Microsoft's Teams Office repository under production releases. The file is labeled "Teams_windows_arm64.exe", but the truth becomes a reality when installing it. Not only does this version install, but checking under Task Manager > Details > Platform, you can see Microsoft Teams running as 64-bit.

Previously, running Teams on a device like Surface Pro X would show it as 32-bit because it runs in emulation.

The version number of the app appears to be

It's a bit too early for us to put it through its paces for performance, but for those with Windows 10 on ARM PC, you can try the file yourself. You'll need an existing Microsoft Teams account to get started or sign up for a free account.

  • Its working fine for me, too I dont have another meeting till monday to try it out well, but it installs and doesnt show up as 32bit on task manager
  • I just loaded it from the general website and it reloaded as 32bit. How do you get to the download repository? EDIT: Nevermind, found the URL on the Reddit link. Downloaded and confirmed new revision # and not running 32bit. Happy dance.
  • Yeah, reddit link or the link I put at the end of the article go to it.
  • Teams still isn't in the Store though. Kind of strange.
  • Yea, why wouldn't they put Teams into the Store? Maybe because that then necessitates it gets updated via the Store which would require a rewrite of that code? Today Teams (and Office) do internal checks/updates.
  • Teams has it's own automatic update feature built in, which is not allowed in the Windows Store.
  • That's not the reason. Just incompetence
  • Considering how bloated Teams is, I wonder how it will affect the battery life on ARM.
  • Well I just rebooted and launched Teams. It's currently sitting at 330 MB before I've done anything so still bloated. But previously, it would easily exceed 600 MB so that's good, I suppose. RE: battery life, not sure how that is relevant since it isn't relying on emulation that burns CPU time. But memory management should be better.
  • Yeah, previously 1 hour meeting suck out half of my battery in spx. hopefully, with this version, it could be much better.
  • It's much better compares with the 32-bit version. I've used it for meeting, and it seems much stable also.
  • All Electron based apps are bloated.
  • Teams is ElectronJS based? Microsoft didn't even use it's own toolkit for it?
  • And so is Visual Studio Code, it's the first Microsoft Electron app to get an ARM64 port.
