Activate Windows 8/8.1 Online After Installation




 *  Note
When installing Windows 8/8.1 Enterprise, it will not ask for a product key during installation since Microsoft allows you to use it without being activated for a free 90-day evaluation period. Instead, you will need to enter your volume product key and activate before the 90-day evaluation is up, or uninstall Windows 8/8.1 Enterprise.

If you like to give Windows 8/8.1 Enterprise a try, then you could download and install it from the links below.


1. Do step 2, 3, 4, 5, or 6 below for how you would like to enter your product key and activate Windows.
