Willie,
Your E Machine may or may not have a MS sticker with the 25 digit alpha numaric code in five groups of five with dashes between the groups. There lies your license access. If you do not have that sticker, no problem. Download Magical or Magic Jellybeans, go to downloads on C: drive and click the exe file you downloaded, get a pen and paper and record the 25 numbers and letters and then, take the removable side, left as you look at the front,e a permanent marker and, very, clearly write that code inside that panel.
You can also go to Rapid River's web site and download the correct x15 or x14 XXXXX iso image and get a nerd like one of us to write OEM in place of Retail and you have a manufacturers copy, ready to burn. Write the code on the DVD twice for insurance and zingo, you're a computer nerd.
