Do you mean your HDD's capacity is 20 GB? That's too little, in case you want to install other softwares too. It would become full soon. You also need to buy a Win7 license. I'm not sure, but I think you cannot upgrade without an installer medium (DVD, pendrive). Also, Windows XP support is over just means, you won't get any more updates for it. If you take care of your web activities and scan for viruses, you won't have problems with it. 2× editiert, zuletzt 15.06.14 23:13:36
