First off... Windows 7 is the only way to go. It is stable, and you get to access all those sweet videogames. But before all that, the standard software. Your specific hardware drivers. The latest ones. set the schedule now. Defrag should run once a week, I run mine in the night on Wednesday. if you shut the PC down after every use though. get AUSLogics Defrag. It will run if the computer is idle for 15 mins. Google Chrome - https://www.google.com/intl/en... Google Picasa - https://www.google.com/picasa/ Ccleaner - http://download.cnet.com/CClea... Try and find a version of Office that does not require a monthly bill. Office 365 is a very horrible idea and I have no idea why someone would pay for it monthly. then again there is open office which is free.
