در رابطه با registry .....

سلام دوستان !
من می خواستم یک برنامه بنویسم که بتونم باهاش CD -KEY windows رو از Registry بخو انم
و code که براتون اینجا میزارم رو پیدا کردم !
توضیحات کد:
1.میاد Registry->HKEY_LOCAL_MACHINE\Software\microfost\windows nt\DegitalProductID میخونه!
2.DigitalProductID از 164 بایت تشکیل شده Encrypt هم هستش !
3.میاد از بین بایت 52-66 رو بد از یک عملیات Decode میکنه !!!
که در این قسمت به مشکل بر خوردم!!
چون به جای اینکه به من Char مختلف cd-key رو بده فقط BBBB-BBBB-BBBB-BBBB رو بر میگردنه!
من هرچی فک کاردم و گشتم که رهه هلی پیدا کنم نتونستم!
کد برنامه رو اینجا میزرم ببینین شما چیزی به ذهنتون میاد !
