How to disable Core Isolation on a Surface Book 3?

Good day everyone,

I' trying to run Nox Player (https://www.bignox.com/) on a new Surface Book 3, but Windows keep telling me it's not compatible. Following Nox's how-to guide, they say to disable Core Isolation, but according to Windows that setting is managed by the system administrator, when the Surface Book 3 is my own machine, with only one account on it, and of course with admin privileges.

I've tried a common gpedit.msc "trick" of changing a setting and then changing it back, but the Core Protection setting is always out of reach.

Are there special steps I need to take to disable Core Isolation on a Surface Book 3?

Hi, BriareosKerensky!

 

 

Thanks for reaching out to Microsoft Community and posting your inquiry.

To disable Core Protection, it is required to enable Intel VT-x. There's a thread that discusses how to do so and can be found at this page: https://answers.microsoft.com/thread/b9057c59-eb8a-4221-85c4-90a3d44edd55

By design, this is turned off by default on your Surface Book 3 for the device's safety. Furthermore, Memory integrity is a feature of core isolation and it is important to have this enabled. Turning on Memory integrity setting helps prevent malicious code from accessing high-security processes in the event of an attack.
