Since I bought my A9 I had read many comments recomending to upgrade to Windows 7 Home Premium or Ultimate edition for fast performance. After installing some editions of Windows 7 in my A9, I noticed that the speed (or performance) problem was not really with Windows 7 Starter edition. My conclusion is that Archos engineers installed the included Windows with other "shell" software that make it inefficient. So, how do i get better performance with Windows 7 Starter edition ? Just installed your OS from an original Windows installation disk. This is very simple. If you have a genuine Windows installation disk (any edition ) you can modified with notepad, the "ei.cfg" file included in your edition to change it from whatever it is, to "Starter" edition. To do that you will need to make a bootable USB and copy all your Windows Installation Disk software to it. After that, explore what is inside your USB and you will find the "ei.cfg" file inside the source file. Then you can installed and activate your A9 with a fresh version of W7 Starter. Just use the included license in the back of your A9. Your license will only be good for the "starter" edition. Remember to format your main "C" drive before installing it. After installing W7 Starter, you will need to installed "Intel graphics" and "Touch" drivers. The results would be amazing !!!
