Myth: Speed Up Windows 7 Boot Up Time

Can a ?Secret? CPU Setting Really Improve Boot-up Time? TuneUp Blog about Windows

There supposedly was an article on the Microsoft KB (KB959233) that said Windows was only using 1 core. This article was removed due to the fact that the statement was false. This setting is really only there as a debug option. Also one other reason not to do it, is the fact that some people have reported major issues just booting after setting this.

Awesome! Thankyou. I actually spent a lot of time this afternoon trying to find anything at all on this; and I could not. I did not use the term "myth" in my search and so I actually couldnt really come up with anything to say there was anything wrong with the feature.

I had also read about it on technet so I figured it was totally safe.

Anyways, maybe i should change the title of my thread to HOW NOT to speed up windows 7? hahaha
