Upgrade as quickly as you can. During the implementation the software will run a diagnostic on your PC to ensure that you can run Windows 7. I will also tell you what software you must delete on your machine to do the upgrade - and it will also tell you other software that MAY NOT work after the upgrade. Do yourself a favor and delete that software as well - it will give you problems during the upgrade. If you do that you won't have any problems and you will be very very very happy!
