I just ordered an XPS 15 Touch, which has Windows 8.1 64-bit English. I would like to upgrade the machine to Windows 8.1 Professional 64-bit English. I need to know how to do the upgrade proeprly. I have a few questions:
Is the upgrade a safe thing to do?
Should I do the upgrade myself or get a Dell technician to do the upgrade? What do you recommend?
If I do the upgrade myself and run into issues, who should I contact? Dell or Microsoft?
Does the upgrade affect my extended warranty?
