Windows 10 Build 19045.5794 Available to the Release Preview Channel

This update includes the following features and improvements (items bolded in brackets indicate the area of the change being documented):

[Graphics] Fixed: The check for GPU paravirtualization was case-sensitive in Windows Subsystem for Linux 2 (WSL2). This issue might potentially cause GPU paravirtualization support to fail.

[OS Security] Fixed: Updates to the Windows Kernel Vulnerable Driver Blocklist (DriverSiPolicy.p7b). Additions have been made to blocklist drivers with security vulnerabilities that have been used in Bring Your Own Vulnerable Driver (BYOVD) attacks.

    This Windows 10 Build 19045.5794 update mainly improves security and graphics. It fixes a GPU paravirtualization issue in WSL2 and updates the kernel driver blocklist to protect against BYOVD attacks. Nice to see Microsoft still tightening up Windows 10.
