Microsoft can help you since they made Windows (of course), here is the main page for getting ready for the service pack,I kinda have the same problem. The thing is that I have Win 7 64bits (no service pack 1), so that means that I can't install the last version of .NET Framework 4.6.2, because it requires SP1 for WIN7...I'm stuck in there and I don't know how to fix this problem
