April Tip regarding MSCONFIG /numproc - true or false?

[brundle]

"If you're running Windows XP or Vista with a computer that has a multiple core processor such as the Intel Core 2 duo you can increase how fast your computer boots up by having it use multiple processors for its boot sequence. Following the below steps to have Windows do this for you.)"

Can anyone verify this? As far as I'd been aware Windows boots using all available cores, this setting only configures it to use less or a specific number for troubleshooting - I've googled and found differing opinions....

I'm pretty sure it's false. I remember seeing a high-profile tech blogger writing it as FUD. might of been Mark Russinovich.

/numproc=number
This switch sets the number of processors that Windows will run at startup. With this switch, you can force a multiprocessor system to use only the quantity of processors (number) that you specify. This switch can help you troubleshoot performance problems and defective CPUs.

There are no performance or any other gains by changing the default setting. There could be issues, however. Vista will use fully all available processors once it enters kernel mode at the end of startup, no matter what you set for the number of processors in MSCONFIG.
