Solution

Set the cursor on the 0000000000006D30 line (begining of the IsFeatureEnabled function). Right click - "Synchronise with" -> "Hex View" should be checked.

Open Hex-View window, press F2, type 33 C0 40 C3

That means the following:

   xor eax, eax ; 33 C0
   inc eax ; 40
   retn ; C3

If you want to save this in a file, do the following.

Copy 10-20 bytes around your patch and find hex string (e.g. "50 DE 64 11 ...") in a hex editor (WinHex, 010 Editor, Frhed, etc.), make sure enough bytes are copied and only one sequence is found, replace original bytes of the function with patched bytes. Try to execute your patched version. Sometimes it's a bit harder due to the relocations. But this is a next level.

P.S. I don't support software piracy. So, do this in the education purpose only!
