Disabling Virtualization --> VT for Direct I/O also allowed Memory Integrity to be enabled. I suspect those having issues upgrading to 22H2 should be able to if they disable VT for Direct I/O only leaving Virtualization Enabled.
Hey all, Just wanted to report a minor bug with a fresh install on Windows 11 22H2 on XPS 15 7590. When trying to turn on Memory Integrity under Device Security / Core Isolation, upon next reboot i get a blue screen with Inaccessible Boot Device. Yes, I'm using the latest Intel Chipset Drivers and XPS 15 7590 firmware. Yes my Windows 11 is up to date.  expired on August 2, 2020. DELL-Admin>
