Windows 7 users, install Service Pack 1 before April 9th 2013

Attention all Windows 7 users! Microsoft will no longer support security and performance fixes on your computer if you don’t have Service Pack 1 installed by April 9. Service packs contain Microsoft’s software updates, and typically are part of the updates that many people have their computers set to automatically receive. Since Service Pack 1 came out nearly two years ago, there is a good chance it is already installed on your computer, but if it’s not, the update will expire April 9.

To find out if SP1 is already installed on your computer,
Go to the Start menu
Right-click on Computer
Choose Properties
At the top of this window, under the label Windows Edition, Service Pack 1 will be listed if already installed
If you do not see it listed,
Go back to the Start menu
Select All Programs
Choose Windows Update.
On the left hand side, click Check for updates.
After it is done checking, look at the list of available updates.
If you see Service Pack for Microsoft Windows (KB976932), click OK.
Proceed to Install Updates and follow the instructions on your screen.
