There it teaches me how to optimize my PC for HL2.
It says go to file > export > to make a backup for registries.

IN which folder or directory do I go to to do that?

I am running Windows XP with NO service packs.

Thanks.

Why dont you have SP's installed? You can save them where ever you want. Just name it registry backup..

star>run type "regedit" without quotes, right click topmost icon on left list (should be "my computer") click export, save it to desktop or my docs or something....

Go to start, run, type regedit. Go to file, then export, find the location you want to store it in and click export.
