Reformatting my Laptop

Howdy, so I'm feeling the need to reformat my laptop (Asus G74SX-BBK8) because of all the bloatware, and the fact that I have hundreds of gigabytes of space that I cannot account for. I'm going to install Windows 7 Ultimate instead of the Home that is already on here. I'm upgrading to 16gb of 1600MHz RAM later on, so Ultimate will come in handy.

So far, to prep everything, I've gone through every folder on my C:\ drive for my user to move or delete any files I come across. So far I've managed to delete over 80gb of shit, and I made enough room on my second hard drive to archive my TrueCrypt partition on it. My Backup folder for everything else is 200gb, so I'll probably have to do some tweaking to get everything to fit properly.

Is there anything I'm forgetting, or I should know/do before/after going through the installation process?

 

Make sure to install/update all your drivers after you install Windows 7 Ultimate. Thats about all I can think of really, it is quite simple and straightforward. Goodluck
