i have win7 so i cant tell, but my fried says there is problem with win10 when you are using mod, if you are using some addons, bin, dta... it have chance to crach, he said its before mods are created for OFP not CWA so it may crash before win10 i dont know if its true (i think not), but maybe. i have win7 using many mods and have no crash
