Many brand-name PCs, rather than giving you a regular Windows CD, give you a restore disc, which returns the laptop to factory configuration–junkware and all.
Just about the best thing you can do to pep up a brand-name PC’s performance is to do a clean Windows install. So here’s how to download a regular Windows CD so you can do just that, when needed.
And there’s one other situation where you’ll need this. If your PC came with 32-bit Windows and you want to upgrade to 64-bit, or it came with 64-bit and you need to downgrade to 32-bit for compatibility reasons, you can download the other version. The CD key for one will work with the other.
