    Only do this in case your computer crashes often due to error code 0xC0000005, otherwise it’s best to just leave it on for better security.

    Any legal games protected by SECUROM should be DISABLE SEHOP,OR the game will be crashed.Like BATMAN ARKHAM CITY

    It is better to delete a value rather than setting it as 1.
    Because, when it disabled explicitly, it will become disable also in few process of enable implicitly.
    (It is similar to the relationship of OptOut, OptIn and AlwaysOff of DEP.)

    You’re better off installing EMET and configuring DEP/SEHOP/ASLR/whatever exceptions on a per-process basis when you have problems instead of turning this off globally.
