How to keep your pc running fast and smooth
Make sure you have a good set of hardware to meet minimum requirements.
Have a large capacity hdd and ram. Also, realize that all of the information on the drive that your current operating system is installed on (probably your c: drive) will be destroyed during this process.
If there's anything you want to keep, you should back up the drive to keep files. To install : Boot from the windows dvd or usb device.
