I am not clear how you expect Microsoft to assist you. What exactly is the problem you now have?
If you reinstalled Windows 7 it will take a long time to install 4 years updates. It will take less time if you installed a copy of Windows 7 incorporating the SP1 update. You will also need to reinstall drivers.
Notes on using Windows Update:

You do understand that most persons helping users in these forums have no connection with Microsoft.
