   Here is some pseudocode that should work:

   // =================================

           Load Windows Startup Screen;
           Do Optical Character Recognition on Image;
           if (Text Found Contains "95")
               You Have Window95;
           else if (Text Found Contains "98")
               You Have Windows98;
           else if (Text Contains "NT")
               You Have WindowsNT;
               Attend Microsoft Product ID Days;

   // =================================

   An alternative method is:

   // =================================

           Run Netscape;
           if (Blue Screen Of Death contains register dump)
               You Were Running Windows NT;
           else if (Fatal Exception occurred in VxD)
               You Were Running Windows95;
           else if ("The System Has Become Unstable...
               It may be possible for you to return to
               Windows..." gives you false hope before
               hitting CTRL-ALT-DEL again)
               You Were Running Windows98;
           else if (Everything is Fine)
               Attend Microsoft Product ID Days!;
   // =================================

   But the most practical WinXX detection code is:

   // =================================

           try { outp(...); }
           catch() {  You've Got WinNT;  };

           Write to your own network port 139;
           if (Blue Screen Of Death)
               You've Got Win98;

           Create four "device contexts";
           if (You can't create one more)
               You've Got Win95;
   // =================================

   Other methods include:
   (1) Measuring the size of the End User License Agreement (EULA);
   (2) Checking the version of Solitaire;
   (3) Timing the Reboot process;
   (4) Checking if the path "C:\WINDOWS\PROFILES\ALL USERS\
       1000-POUND USELESS MSCE BOOK" exists.
