Most folks don't take the time to see what slows up computers.
Things that speed it up include:
1. Having very little if any programs starting up on boot up
The issue here is not at all how *many* automatically start when you
boot, but *what* the programs are. Some programs have a large effect
on performance, others do very little and any effect they have on
performance is so little as to be unnoticeable.
2. Only loading 50 fonts on boot up
Although this was an issue in older versions of Windows, it's no
longer an issue in Windows XP.
Generally overrated, but it could make some difference,
... and minimizing "space hogs"
"Space hogs"? Exactly what do you mean by "space hogs"? If you are
talking about disk space usage, it's irrelevant to performance.
4. Deleting those .txt, other language files, and other unnecessary
files that the OS and other programs install
Again, that's irrelevant. How much disk space you use doesn't affect
performance.
5. Using registry cleaners as well as manually deleting leftover
entries from removed programs
Ugh! That's very poor advice. Registry cleaning programs are *all*
snake oil. Cleaning of the registry isn't needed and is dangerous.
Leave the registry alone and don't use any registry cleaner. Despite
what many people think, and what vendors of registry cleaning software
try to convince you of, having unused registry entries doesn't really
hurt you.
The risk of a serious problem caused by a registry cleaner erroneously
removing an entry you need is far greater than any potential benefit
it may have.

I use 4 GB out of my 18.6 GB hard drive.
Fine. And that may be good, since it leaves you with space you can use
in the future. But using a small amount of disk space doesn't improve
your performance.
