Go to (http://support.asus.com/Download.aspx?SLanguage=en&m=X450JF&p=3&s=523) and select your windows version. Then it will link to the downloads. However Asus says before you do anything, you must run windows update repeatedly until there are no more recommended and optional updates from windows. Windows should have most of the drivers you need. Specifically what drivers do you think you need? Are you also saying win 8.1 can not unzip a file?
