I would start with those Dell recovery disks -- and do a factory rollback. Once set up, you can get rid of any and all crapware (optional) -- then install the few programs you need (e.g. Office). You are good to go if you don't plan on any internet visits.
But if you plan on surfing the net, then make sure Windows Firewall is turned on -- then connect with the web -- download Microsoft Securities Essentials -- and get all the MS Windows and Office and whatever else app updates you need. You are now good to go.
After performing the above, there is no way any old files will remain to slow down your laptop or create any kind of havoc. They won't even be accessible. But if you are truly paranoid about wiping any and all remaining traces of old files -- you can download CCleaner (free) -- and set it to wipe all unused disk space. That should take care of it.
