Decide whether to enable or disable virtualization.
Decide whether to enable or disable virtualization.
I've just realized virtualization features are active. I wasn't expecting them unless I was actually using a VM, like switching operating systems inside Windows. Since I don't rely on that, it makes sense to turn them off. I haven't noticed this before on any of my computers. It might have triggered during a recent BIOS update, but after resetting it to defaults it's now on by default—unusual. Regarding Intel virtualization and VT-d, it seems they're enabled by default but can be adjusted. Whether it matters depends on your needs; if you don't use virtualization, disabling it is safe and reduces potential risks. As for security, having these features on doesn't inherently harm performance or safety, but it could open avenues for attacks if misconfigured.
If you're not relying on virtualization, you likely have the option to disable it, although I don't believe it's a significant concern. From my perspective, keeping it on isn't necessary, though it doesn't affect anything. It poses no security threat.
If no virtualization is in use, disabling it isn't necessary. Although there might have been a recent VT-d exploit, keeping it on isn't essential from a security standpoint. EDIT: Confirmed correct. https://www.intel.com/content/www/us/en/...00442.html Updated May 12, 2022 by Levent
Windows employs virtualization guidelines to boost safety. https://docs.microsoft.com/en-us/windows...es/oem-vbs There’s no solid reason to skip this.
HVCI requires CPU to support it, (which is exactly why Windows 11 had CPU requirements). If your CPU doesnt support HVCI and you dont make use of virtualization anywhere, there is no reason to keep it enabled. That being said keeping it enabled is also fine as long as user is not a total dumbass or doesnt have government secrets on the machine.
