I've have looked at and considered Question about potential ISO infection and ISO verification and How do I check the hash of an ISO?

I've been concerned about security and I have been reading a lot about stuxnet and hearing a lot lately about the leaked NSA exploits and the more recent leaked exploits NYtimes

This made me consider the importance of a clean installation of Windows and how the Windows install itself could be used as an exploit.

Can an iso downloaded from Microsoft.com with seemingly correct hash truly be 100% safe to use on a Windows machine?

- Is there room for an exploit after a clean download?

  • After the iso is downloaded could there be an exploit to

  • Spoof the SHA1 using something similar to link

  • Trick common software like hash calculator that checks SHA1 into saying that it is correct even if it is not.
  • Compromise USB/DVD imaging software like unetbootin / win32 disk imager / rufus etc. during the "burning" of the iso.

The .iso would be downloaded from:

https://www.microsoft.com/en-us/software-download/windows7

Windows Resource Protection

Windows Resource Protection aims to protect core registry keys and values and prevent potentially damaging system configuration changes, besides operating system files. wikipedia

  • An answer mentioned that Windows Resource Protection is enough to prevent someone from modifying an iso of Windows. I do not think that is true because there are plenty of programs to modify Windows iso. I fail to see how that will prevent a virus if you can add custom programs to the iso that can run at boot.

    If you can prove that Windows Resource Protection is enough (which I don't think you can after looking at the links below) please explain why in your answer.

    Here is an an example of programs that can modify a windows iso. Just so people do know that it is possible and how easy it is. nLite and RT7lite
