Congrats. You have joined the growing number of tech enthusiasts who clean reinstall to overcome factory bloatware which is now enforced by all manufacturers except on business computers.
You should make your Recov Disks anyway as sometimes Recov partition won't run even from boot after reinstall. It also frees you to consider wiping the HD to get the cleanest possible install. Most of the useless Toshiba utilties (which have much leaner better versions built into Windows 7) also won't run in a clean install since they lose their links. Go completely clean here: http://www.sevenforums.com/tutorials...tallation.html
The installer is mostly driver
-complete with newer arriving quickly via optional Windows Updates. Any drivers
then missing in Device manager can be found on Toshiba Support Downloads webpage for your model. Only change drivers if performance dictates, starting with video and chipset.
Install programs slowly to gauge performance after each. Don't let any write themselves into msconfig>Startup to become freeloaders on your RAM/CPU. I only allow AV and gadgets. Run a lean mean AV like free MS Security Essentials which installs in 30 seconds, updates, runs Scan then becomes invisible unless there is a threat.
When done, clean and order the HD perfectly with state-of-the-art CCleaner ("Run Cleaner" and registry tabs) and Auslogics Disk and Registry defraggers monthly.
Then save a Windows 7 backup image so you never have to reinstall again, just reimage the HD or replacement in 15 minutes from DVD and image.
