Win 8.1 is preinstalled, after max. Is 1 hour of computer set and aktualisert.
McAfee should be uninstalled before a reasonable Suite is installed.
Otherwise, not much scrap software pre-installed, a matter of taste what you really need.
After the startup process is very fast. Open programs without significant delay.
The Zenbook a looker! Elegant and stable housing. Very quiet. Very good battery performance.
I have to notice anything really negative.
Of course, I have pressed the start button more often because I suspected the Delete key there ...
I think it is the right and best Ultrabook in the 700 Euro price class.
