In the first reviews I have hardly dared to carry out the whole Win 8.1 installation procedure, with my limited computer skills. But with Win 8 stopped the Internet permanently, nor had the computer long periods where he did not respond, the touchpad did not look properly. And then worked on the proposal to install Win 8.1. This is what I also made simple and lo and behold, now everything is great. The stupid apps are gone, you can shutdown the computer properly again, and most importantly, it runs without stalling properly. The Internet connection is also there throughout. And I have a 17-Zoll.laptop with DVD drive, good characteristics and for 400th Cool.
