You mean old PC games right. There is some methods you could try it out.
01. Right click on the game application file and click properties. Go with the Compabilities the check with it. (Most will not work)
02. Get a VirtualPC or VMWare. Install your old version of Windows through one of the programs. Then Install the games and play it.
03. Install older version of Windows directly on your PC. This will make it as DualBoot OS. (Well, mostly I personally choose this method.)
