UnPackMe (.NET)

DNGuard HVM v4.94 Hey, Dropping my second UnpackMe challenge, made just for fun. This one’s a bit tougher than my first, but still very doable.

So I made this little program, The objectives are: [Unpackme] You should unpack it and get the cleanest code possible. [Crackme] In the textbox where the HWID is displayed you must modify the text and write something else in it.
