    This sounds useful, but I wonder: If I remember correctly one of the big improvements in Vista was faster boot times so why isn't this enabled by default if the computer has several processors or cores?

    Would there be any negative effects of doing this?

    The same tip has been seen on sites such a lifehacker and the people there seemed unanymous after trying it that it made no difference- if I recall correctly one person claimed to know that Windows used both anyway whilst booting and this was a way to LIMIT rather than expand the use of processors.

    I could be wrong though as this is coming from somebody inside MS...

    According to MS documentation this is a debug setting. It will not make your system boot any faster as far as I can understand... As northerngeek said this will only limit the number of processors used during boot.

    Albert1690: How this could have negative effects on performance? Well, I guess if you set the setting to 2 cores and then forget about it (most likely scenario), and then after a few months you upgrade your system to a quad-core or better processor, you would then effectively have limited your boot sequence to only be using 2 of your 4 sparkling new cores.

    My recommendation; leave it to the default setting.

    Hey, thanks for replying Smiley Feel much better about just leaving it; figured I should ask before doing so.
