Quake 1 works fine on almost any Windows OS, including XP and Windows 7. If the original DOS version isn't working (You can try setting it up with DOSBox) then you can try a source port.

Winquake (Good for old school look of original game, and works fine on XP.) - ftp://ftp.idsoftware.com/idstuff/quake/wq100.zip

GlQuake (An official graphic upgrade to Quake on OpenGL, making textures smoother and enhanced lighting. However, the gun lighting and scaling are off.) - http://www.falconfly.de/downloads/patch-GLquake-v098.zip
