Ah, good to know. I have only just installed the update yesterday, uninstalled the 446.14 driver that automatically installed after updating from 1909, then installed 450.99 and the toggle enabled and i restarted as it states. Haven't checked if it stayed restarted in my situation yet, but something to check later tonight. Edit - it stayed enabled in my case, guess its working! Also noticing other issues with build 19041.264 when testing at work, like: -Hyper-V adapters being present in device manager (even when removing/restarting) after going through an MDT deployment (even though Hyper-V isn't enabled in the feature list) or - the logon script we use with people's Active Directory accounts (to connect shared folders when they login) hanging on the step that connects a shared folder on a server still using the SMB1 protocol (yes, the SMB1 feature is enabled with automatic removal too. I've tried to convince my manager to migrate to an environment that supports a higher version, but we apparently still run required software on the server 2003 machine..). Manually running the script after exiting the script prompt works though.
