and download these, search within the MS website for the KB numbers:
1. If you don't have the SP1 installed - Windows 7 Service Pack 1 for x64-based Systems (KB976932). If you have SP1, skip to number 2.
2. Update for Windows 7 for x64-based Systems (KB3020369).
3. Update for Windows 7 for x64-based Systems (KB3125574).
This is an important step. Before you install any of these updates, you have to stop the Automatic Update Service. In the windows Start Search box type "Services", double click on it, scroll down to Windows Update, double click on that, in the General tab click "Stop" and click OK. You can now install the downloaded updates.
Another important step, these have to be installed in sequence. 1st is the SP1 update, 2nd is KB3020369 and 3rd KB3125574. If you already have SP1, then you do 2 and 3.
Your computer should be up to date and not needing any new updates.
