This one does a really weird thing I haven´t seen in any other crackme, will you find out what it is?

It´s a lot less scary than it looks. At some point you should scream "HEUREKA!"...

Tested on XP and W2k. Please don´t use on other OS versions!

Have fun, write a keygen!

Hi warrantyVoider !
Did you test and sure that all explorer.exe in Win2k/XP will have the string "This program xxx" at addess 0x100004E. I think I can hardcode this string in my keygen, and this way is shorter than using Toolhelp API/PSAPI to read explorer's memory.

of course, feel free to hardcode this string. It seems to be identical in W2K and XP. Also it seems this string does not get changed in international versions of Windows. (Hardcoded in the compiler I guess.). Greetings, WV

ps: While the string is identical, the image base is not. Under W2K explorer.exe loads at 0x400000, under XP it´s 0x1000000.
