"This compatibility fix when installed will provide Windows 2000/XP with the compatibility settings required for these operating systems to run the X-Wing Collector Series and X-Wing Trilogy versions of X-Wing & TIE Fighter (Also known as X-Wing 95 & TIE Fighter 95) with Hardware 3D Graphics acceleration turned on. The fix also stops the TIE Fighter Launcher from asking you to install DirectX 5.2."

I have many of those titles also but the DOS Tie Fighter Collectors' CD-ROM is the best for me. The difference with those Windows games is that none of them use the nifty iMUSE system that gave the originals the dynamic MIDI soundtrack.
