I have recently bought a new notebook which came with W7 Home Premium OEM and it's very fast except for the HDD. So, I want to replace that and start with a fresh installation. I won't work from a backup, because I also want to get rid of all the clutter from the manufacturer. It's an Asus, BTW. How do I go about reinstalling Windows 7 Home Premium OEM? Can I just download a DigitalRiver image, for instance X17-58997.iso and go from there? Or are these Retail images which for some reason won't work with an OEM key? Regarding the OEM key, can I just enter the number on the sticker upon installation, or would using Advanced Tokens Manager by Josh Cell be preferred? Thank you.
