Do you know the differences between the Windows Update and Microsoft Update web sites? I am not sure if most people even realize there is a difference between these two services. For the most part they look very similar, but there are some key differences between them.
The older Windows Update service only allowed you to update the Windows OS with hot fixes. If you had Microsoft Office installed on your computer, then you would need to go to the Office Update site to update these applications.
Fairly recently Microsoft merged the two sites (Windows Update and Office Update) to create the new Microsoft Update web site. Now you can go to one site and keep your Microsoft Windows and Office applications up-to-date with the latest hot fixes.
As I said earlier, the two sites look very similar, but the way you tell the difference between the sites is by looking in the upper left-hand corner of the browser after you have gone to the Windows Update web site. If it says 'Windows Update', then you're on the 'Windows Update' site. If it says 'Microsoft Update', then you're on the 'Microsoft Update' site.
If you're using the Windows Update site and want to start using the Microsoft Update site instead, go to the following page and press the 'Start Now' button.
