    Probably a weird question, but if i have a Windows 7 Untouched ISO, and i slipstream SP1 into it, will the newly Win_SP1.iso's md5 hash match the hash of a untouched SP1 disc?

    No, of course it wouldn't. Even a byte-sized change in the ISO would alter the hash. And although slipstreaming under Vista/7 isn't quite in the same sense as it was with XP - it is still feasible via the WAIK (although more complex).

    Probably not no.

    ok, thanks.

    Did not know the timestamps, also influence the md5.

    Just wondering, if timestamps influence the md5 hashes, how does it work, if i make a new iso, with the use of delta's, my newly created iso, has the same hash as the MSDN one, would using delta's not also effect the timestamps?

    No, basically Delta's use a byte to byte comparison of the source and target files and makes a patch only containing the differences, if you later apply that patch to target file it is 100% identical as the source file
