Re: [ros-dev] [ros-diffs] [hbelusca] 66192: [WINLOGON][WIN32K] Move the shutdown privilege check from winlogon to win32k (function "UserInitiateShutdown") as it should be done. [WIN32K] - Introduce the pair of UserInitiateS...

[Alex Ionescu]

This would be the win32k 0 day that's been blogged and unfixed in Windows
for over 4 years now, and which allows the Surface RT to be jailbroken. You
really want to fix this? :( What about hackcompat?!

Best regards,
Alex Ionescu
