I found a game for the pc thats for windows 95/98 will that work with windows xp,vista, 7 ?

it might work, you can change the appearance of those os to windows 95/98to but the os is same they just mimic the look dont think they alter the program only way to find out is try it

Worst case is it will tell you the resolution of your screen needs to be changed to format the game. It will look very funky compared to games made for Vista, but it will work.

Once you are done with the game however it might leave your resolution set to the game settings. You can fix that though by going into the control panel and changing your "appearance" back. I would make note of those settings before you play the game so you can change them back if you have to do it manually.
