The Stop error occurs in the Win32k.sys driver. You may receive the Stop error when you use the keyboard to activate and control the menu items of some programs.
This problem may occur when you run a program that dynamically creates and deletes menu items within a loop. If you use the keyboard to control the program menu, you may trigger a race condition in the menu handler of the Win32k.sys driver during the MNOpenHierarchy function call.
