No, and you really just need to forget about the registry altogether. Far too many people go spelunking in there, or run a registry program, and then find that their OS is now not functioning properly.
The registry is not some secret black box full of tweaks that can make your system run faster. Windows already comes about as highly optimized as you can get, and in the cases where it's NOT as tuned as it could be, there's a very good reason for that.
I don't care what OS you're using, there are only three things that will have any measurable effect on system performance.
3: Limiting the number of running programs
That's it. All those various speed up programs basically just go in, shut down non-essential Windows services, and delete shortcuts for programs that run at startup. Seriously. They basically just limit the number of programs running, so when you reboot your system that first time you think, "Wow! This is so much faster!" But all you're really doing is trading a little startup time for longer load times later as those programs and services have to be started manually later. Also, those "free RAM" programs are all scams. Don't waste your money. You also don't want to fall into the trap of thinking you need a whole lot of free RAM. Free RAM is wasted RAM. The OS tries to use as much free RAM as it can to speed up your system, and will automatically free up memory when needed by something else. When you think about it really... If the RAM is free, it's just sitting there idle, not doing anything. What possible use could that be to you? It's like having storage garage that you never use. It just sits there, empty, but you're paying for it every month. The proper thing to be asking yourself would be, "Why?!"
CPU, RAM, and limiting the number of running programs. Those are the only three things that will consistently make your system faster. So wherever it is you got the idea that prompted this thread, never listen to them, or visit that site, again. If this is any indication of the kind of "information" you'll get, you're better off without.
