Microsoft offers periodic major upgrades to its Windows operating systems. These are called “Service Packs” and are usually of a combination of improved security, bug fixes, and feature enhancements. If you have not taken the latest service packs for your computer, Microsoft has this handy Service Pack Center site.
To find out the service pack version you are running, go to the Start Menu, right click on the Computer or My Computer icon, and select Properties. The service pack installed will be listed right below the operating system information. If you are running Windows XP, you should be on Service Pack 3 (SP3). Windows Vista is at Service Pack 2 (SP2). And Windows 7 is on Service Pack 1 (SP1).
To install the latest service pack click on the link above, or Google Windows Service Pack Center, and choose your operating system from the three available choices. You know which operating system you need from the little exercise we just did.Share
