Protected files are DEP, UAC, ALSR compatible and should launch in any NT Windows. I'm greatly welcome to hear any suggestions and critics PS: Imports redirection is disabled.

    Hello Tuts4you, Here is a small CrackMe for you. Everything is allowed. Target: Modify the Crack Me that every Password is accepted. I would say this CrackMe isnt to simple, but not that hard either. PS: If the Program says its missing a dll file called "MSVCR100.dll", you need to Download and Install the "Visual Studio 2010 C++ Redistributable". PPS: I didnt protected it with any Protector regards Pain
