I can only recommend. By continuing existing desktop - option is the change from Win 7 without risk. But you do not want to go back and mitterweile I use it only for the programs available in the Apps are not. Microsoft has annoying safety precautions with regard to the necessary account. If you log on with the account with the mobile phone and use services, it can happen that you have to legitimize again the use of the PC (same account). This is done unfortunately without clear warning! It's hard to turn off, but this is possible if one takes cunning. Without Hack just in the account settings. Unfortunately, this is shown indistinctly and explained. In addition, the annoying Microsoft - Email - App does not send Dateine 2 MB! It is a just said that there was a problem with the account provider and you should contact him apart. This is ridiculous and concerns even Outlook - Account! That's why you have to but then a 2nd email Load Program to send to those attachments! It also lacks the possibility the scanner - Email - key with this app to link! Canon wants only other "solutions". For Canon, the issue is thus settled. It is therefore necessary desktop - to use programs from the old -world Win7 ... weak and impotent ... Nevertheless, I recommend further WIN 8.1
