Remarks

The ReleaseKey method maps references to the VK_MENU (18), VK_CONTROL (17), and VK_SHIFT (16) to VK_LMENU (164), VK_LCONTROL (162), and VK_LSHIFT (160), respectively, because the VK_MENU, VK_CONTROL, and VK_SHIFT virtual key codes do not represent real keys on a keyboard.

Access to the Msvm_Keyboard class might be restricted by UAC Filtering. For more information, see User Account Control and WMI.
