Bitlocker on ARM: Question

Hi. I’m hearing mostly pretty good things about the new Snapdragon ARM Windows devices and am in the market for a new laptop. Secure data is a must for me though and the new Surface 7 laptops seem to only have Windows 11 Home. Which to my knowledge doesn’t support Bitlocker.

Windows licences seem to be architecture agnostic so if I obtain a Windows 11 Pro licence and upgrade my Surface 7 Laptop I would be able to enable Bitlocker and encrypt my device? Can anyone confirm this for me as it’s a necessity to have the drive encrypted for me. There are no gotchas like ARM doesn’t support it or it only runs as x86 via PRISM (which cannot be a good thing for something as low-level as that).

This and not yet having much 3rd party VPN support are the main blocks to me buying one. Anybody have info on this? Thanks for any replies.

Bitlocker qoeks on windows home if on a Microsoft account. It uses TPM and stores something on one drive I heard.

ARM64 CPU. An accelerate encryption so no reason it shouldn’t work natively. It’s prudent to have someone confirm it to you though. I don’t have an arm64 laptop that can natively run windows.

Thanks. I don’t think that’s quite right - you’re talking about their Device Encryption which is available on Windows Home ediitons rather than Bitlocker which is not:

I believe it used to be the case that Bitlocker used a more secure algorithm. I don’t know if that is still the case. It does let me export my keys and keep them local only. Whereas Device Encryption requires me to upload the recovery key to OneDrive.

That said, it’s a good point. On my laptop where I will only have the one drive it might be acceptable to just have Device Encryption. Don’t know if I would need Bitlocker for plug in external drives… :confused:

Yeah, I’m certain the processors can handle it. But I want to check if it’s supported by Windows yet. The fact they’re not selling these devices to business yet made me wonder.

I also believe that BitLocker encryption is the best option for security.
