Hello again im back read your reply, yes very interesting stuff,
but whay can we do about this to be able to back up our own purchased software.
I took your advise and searched for anything that started with dilla and look what I found.

C:\windows
cdilla05.dll, cdilla10, cdilla13.dll, cdilla16, cdilla32.dll, cdilla40.dll, cdill64

c:\widows\Prefelch
cdilla64.exe-of-45051A
