Do NOT use programs or anything other method to clear prefetch data.
Bottom line: You will not improve Windows performance by cleaning out the Prefetch folder. You will, in fact, degrade Windows performance by cleaning out the Prefetch folder. I’ve done performance testing that establishes this definitively. In all the many sites that offer this bogus tip, I have yet to see a single piece of actual performance testing.
That BlackViper website isn't very clued up, either. Disabling some of those processes will just make them take longer when you actually need them. For isntance, it says you can disable the activeX installer. Which is fine until you need to install an activeX feature and then the system has to start that process before it can begin, wherein it usually expects it to be running.
The only processes I can see that you could safely disable is the tablet PC process and only if you plan to never use a graphics tablet.
You can spend hours trying to shave 7 seconds off your boot time or you could save money for an SSD and actually see the improvement.
And yeah, I've got my flame suit on. I know there's this massive misconception that if you disable loads of stuff your PC somehow magically becomes faster, but it's all false. However, some people feel the need to say "I tweaked this system" but what they mean is "I just can't leave things alone"
