I currently have Windows 7 Ultimate SP 1 and 425 updates installed plus some other updates. I also have .Net 4.5 installed and its 4 updates(KB2759112,KB2756203,KB2748645,KB2745582). So do i need to install the updates for .Net Framework 3.5.1 (it is showing up on the list of updates to download in the windows updates thingy)
