Departitioning Hard Drive/ Drivers/ Junk on new computers

[whiteunibrow]

Well, my main goal is that when I get a new laptop, I want to efficiently get rid of all the crap that has been put on my system, taking up space and making it run slowly. I could easily do control panel-> add or remove programs for much of the junk, but it seems like a lot of it gets well-integrated, and I don't quite see all of it, and it ends up making the computer run slower.
On this laptop that I got like 3 years ago, I removed a lot of programs, but I think I may have removed some vital ones, or maybe only partially removed some junk ones, or something. My computer has always acted a little funny and I suspect that's why.

1)For my new laptop, would a good solution be to departition the hard drive and reinstall the OS?

also:
2) When you departition the hard drive, do your drivers go away? If so, how does your computer function after that? If not, where are they stored?

Your term departition is better expressed deletion of an existing primary partition. After a lengthy period of time and various program changes a load of junk remains in the system registry when uninstallers tend to leave orphans behind. A good registry cleaning tool can help.

Without periodic maintainence hard drives themselves see fragmentation of files whether system or otherwise where the defragmenter tool in Windows or a 3rd party program like Diskkeeper comes in handy for an automatic schedule. Wear + tear on hardwares along with dust buildup seeing temps rise can also drag a system down.

As for seeing the preinstalled OS on a new laptop wiped completely remember that will likely void the warranty. At this time you can choose what OS will be preinstalled on any new laptop or desktop model from certain manufacturers like Dell. When buying a used anything a good clean install after seeing a drive wiped totally would be advised there.

When you delete the existing primary and even the hidden recovery partition on a new system "you own it" is the expression since everything gets wiped. It would take a data recovery program to retrieve some things. That means having a full install disk for Windows onhand as well as downloading all necessary drivers once the OS is on from the manufacturer's support site for that model.
