TOP 9 Windows Performance Tweaking Myths

@ 2008/08/06
As a tech writer, one of my biggest pet peeves is the plethora of bad advice littered across almost every web site dedicated to system tweaking. Besides the tweaks that simply don't work, some of them will actually cause your computer to run even slower—or worse. Let's examine some of the most offensive myths out there regarding PC performance tweaking, and debunk them once and for all.
* Disabling QoS to Free Up 20% of Bandwidth
* Make Vista Use Multiple Cores to Speed Up Boot Time
* Clearing Out Windows Prefetch for Faster Startup
* Cleaning the Registry Improves Performance
* Clear Memory by Processing Idle Tasks
* Clean, Defrag and Boost Your RAM With SnakeOil Memory Optimizer
* Disabling Shadow Copy/System Restore Improves Performance
* Enable SuperFetch in Windows XP
* Disabling Services to Speed Up the Computer

* Disabling Services to Speed Up the Computer

you should not disable services using the MSConfig control panel but with the services.msc (start -> run -> services.msc ) , there you can manage them better, allow to the start automatically, manual or disabled. You can also check dependencies and see a much better description
