BY doing this you can fix all Winxp to Win7 games ... that crash on Win8\8.1\10 after some time, when the game data suddenly is stored in a place the game will not see ... IF you ever wondered what the "WinXP Compatibility mode" in Win7 to Win10 does, now you know ... it enables games to be only in that 2 gig ram limit, but sometimes the game will crash if it hits a ram wall (since some used 3gigs like Crysis or FarCry 1 and 2)... so this way, games from that OS era work on Win10 64bit OS ... 95% of the time , only had 3 games from 980 tested, did not work... and had to use a Emu WinXP to make then run ... but like most times, even if you patch the memory allocation you have to use graphical DX wrappers , since derpy companies deprecated features from theirs driver sets to push BS it makes theirs cards now RUN FASTER
