[Guide] Enable Windows Device Encryption on XMG FUSION 15 : XMG_gg

Hello everybody,

a buyer as soon as notified us that he can’t allow System Encryption on his XMG FUSION 15 resulting from this message:

Again then I used to be form of stumped by this subject and could not discover a fast resolution. I used to be additionally baffled at how little documentation or assist from Microsoft exists to troubleshoot this subject. Perhaps utilizing closed supply software program for disk encryption shouldn’t be the very best concept? Tell us down under within the feedback…

Disclaimer: proceed at your personal danger

Use the procedures outlined on this thread at your personal danger. Don’t use System Encryption when you do not need a constant backup and restoration technique. Don’t base your private or your organization’s safety danger evaluation on solely on info on this thread. Educate your self concerning the dangers of and alternate options to utilizing Bitlocker. In the event you plan to make use of Bitlocker or System Encryption, be certain to manually retailer your restoration key in a safe location.

We do not provide assist in circumstances of information loss or shedding entry to your system.

Generic Troubleshooting Process

As we speak I lastly discovered time to take a seat down and troubleshoot the scenario. Because it seems, there are a variety of PCI gadgets that Home windows deems to be “un-allowed” – however you possibly can manually put them on a allow-list and make the error message go away. The allow-list is situated within the Registry at this location:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlDmaSecurityAllowedBuses

Whether or not or not this process is definitely secure to make use of is mentioned additional down within the FAQ part of this information. (Spoiler Alert: most likely? So long as you are not working in worldwide espionage?)

The primary downside: Home windows does not inform you explicitly which gadgets are the culprits of this error message. Regardless of how a lot I searched the web, I couldn’t discover any tip on the best way to truly get a verbose listing of the “un-allowed” gadgets the system has detected. Is Microsoft deliberately obscure right here to stop customers from tinkering round?

The one method to discover the culprits of this error message was brute power. A helpful process has been outlined on this put up on superuser.com. The put up offers a Powershell script (mirror) to hurry up the primary two steps of the method. The process boils all the way down to this:

  • Generate an inventory of all PCI gadgets which can be at present current within the system

  • Add all of them to the allowlist. Consequence: System Encryption is now obtainable

  • Now, delete one machine after the opposite from the allowlist and examine between every machine if System Encryption nonetheless stays obtainable

  • Every time you delete a tool from the allowlist that triggers the “un-allowed” error message, manually add the machine to the allowlist once more, skip over it and go forward with the subsequent one

You possibly can apply this process to any PC or laptop computer with Home windows 10, however you’ll more than likely find yourself with completely different listing of “un-allowed” gadgets, relying on the gadgets, firmware and drivers of your system.

Ceaselessly Requested Questions

Once I take a look at this information, I’ve just a few questions myself.

I do not use Bitlocker, System Encryption or I do not know it’s. Does this information matter to me?

Why are eight out of 32 gadgets in XMG FUSION 15 deemed “un-allowed” by Home windows?

Is it secure so as to add these gadgets to the allowlist? Or does this go away me uncovered for vulnerabilities?

  • I do not know for positive.

  • I assume there is likely to be a good cause why Home windows does not permit these gadgets out-of-the-box. Nonetheless, I do not know the way extreme potential vulnerabilities is likely to be. I assume the principle assault vector for machine encryption is to steal a laptop computer that is likely to be locked however is nonetheless working after which use specialised {hardware} to entry a piece of the reminiscence which may maintain the encryption key for the SSD encryption.

  • Essentially the most uncovered instance for such a DMA assault (DMA = direct reminiscence entry) is likely to be Thunderspy, however this explicit vulnerability has already been mitigated in a earlier BIOS replace for XMG FUSION 15. This is likely to be the rationale why you see “Thunderbolt(TM) Controller” being “OK” on the listing above. Is is bodily doable to take advantage of the opposite remaining eight gadgets on this system? I do not know. If in case you have hyperlinks to articles on this matter, please share under within the feedback.

What’s the distinction between “Bitlocker” and “System Encryption”?

  • Bitlocker is simply obtainable on Home windows 10 “Professional” and better. Home windows System Encryption is accessible on all model of Home windows 10, together with “Dwelling”.

  • Bitlocker appears to be a full disk encryption. “System Encryption” is a bit obscure about the way it works precisely. I assume “System Encryption” makes use of Bitlocker expertise. I assume it solely selectively encrypts recordsdata that Home windows deems to be private or non-standard. I’d go away default Home windows system recordsdata untouched, however may encrypt every little thing that’s associated to the person account. To be trustworthy, my search engine abilities can’t discover a clear definition. Microsoft appears to be utilizing “Bitlocker” and “System Encryption” typically interchangeably corresponding to on this article from 2019, making the distinction between these two much more blurry. Thanks, Redmond! 🤡
