The truth is most people won’t notice any difference in how Windows 7 looks or operates after installing this update. Believe it or not, that’s actually good news! It means that Microsoft learnt from their mistakes with Vista and turned out a Windows update that was relatively problem-free, right from the start.
The new features are reserved for Windows Server 2008 which shares the same foundation as Windows 7.
However, it is still important to install this update from a security perspective. You want to keep your computers up-to-date to help ensure you are protected from “security holes” as much as possible.
And for those still clinging to Windows XP, unless you are completely attached to the almost nine year old system, the wait to upgrade is over.
