If you have a computer running Windows 7, then you probably have seen a balloon popping up from the lower right corner alerting you that there are Important Updates waiting to be installed. One of them is Windows 7 Service Pack 1.
Things to know:
Windows 7 Service Pack 1 has been out for more than two months. If you think it may have already been installed, you can check by clicking on Control Panel / System And Security / System. The service pack will be shown at the top if it has been installed.

Nothing will appear to have changed on your computer after you install Service Pack 1 but you will have the latest security updates and bug fixes. Here’s more information about the service pack.
I don’t expect anyone to have trouble installing it. There has only been one rare issue that you are guaranteed to avoid if you follow these instructions.
If you are a Windows 7 user, follow these steps on or after Wednesday, May 11. Your computer will be tied up for 45 minutes.
When you log back in, you will see a message confirming that the service pack has been installed. You’ll feel proud and happy, probably a little tired after such an emotional time, perhaps a little weepy. It’s to be expected.
Chances are you also saw Internet Explorer 9 listed in the Important Updates. I’ll tell you tomorrow about what it means to install that.
