Windows 11
Recently, on my laptop I noticed that Windows 11 Core Isolation (and Memory Integrity) were not an option under Device Security. I had thought I saw them before so I looked online. I read that in order for the feature to be active I needed Virtualization enabled. I enabled it in BIOS and, indeed, the options returned and showed active. Why do you need virtualization enabled for this feature if not running VM? Also, I had (2) options...one for Intel Virtualization Technology and one for Virtualization Technology for Directed I/O. Which ones should I have enabled...I assume the Intel VT for Windows Security...but I don't use VM...do I need the I/O setting enabled? Thanks.

It uses a hypervisor protected container to segregate and protect the code integrity checking of device drivers.
It does affect performance slightly.
You want the Intel.

Should I have both of the virtualization settings enabled, or is only the non-I/O setting required? Both are Intel labeled.
