Ok hmm so i play a game that require me to use ctrl/alt/a. normally i would use them separately but in the heat of battles i might accidently press all of them once, the game wise it doesn't do any harm, all three functions works fine but in windows 7 wise it creates you a "sniping tool" alike tool... which to my understanding lets you corp the space on ur screen and save it as image file. (does anyone even knew this shortcuts exists?). so i want to disable ONLY ctrl+atl+a nothing else... and i know there is few third-party program to do that but is there anyway to do without third-party programs?
PS. sry if this is wrong section... since it's kinda tweak to windows 7 so i think this section is closest since it has "customization".
