It uses WinNT/Turla VirtualBox kernel mode exploit technique to overwrite global system variable controlling DSE behavior, which itself located in kernel memory space. Prior to Windows 8 it is ntoskrnl!g_CiEnabled - a boolean variable (0 disabled, 1 enabled) and starting from Windows 8 it is CI.DLL!g_CiOptions - combination of flags, where value of 6 is default options and value of 0 is equal to 'no integrity checks'. If you run DSEFix without parameters it will attempt to disable DSE in a way depending on the system version. If you run DSEFix with '-e' parameter (without quotes) it will attempt to restore DSE controlling variable to default state.

DSEFix based on old Oracle VirtualBox driver which was created in 2008. This driver wasn't designed to be compatible with newest Windows operation system versions and may work incorrectly. Because DSEFix entirely based on this exact VirtualBox driver version LPE it is not wise to use it on newest version of Windows. Consider this repository as depricated/abandonware. The only possible updates can be related only to DSEFix software itself.
