I was reading about ways to enhance speed in Windows 7, and I read that you can enable Windows to boot off of four cores vs one to boot faster.
Is there a reason why you do not want to use all four cores to boot?
Windows 7 uses what's available on the box ... out of the box. You should not twiddle around with the boot process except when you know what you are doing, otherwise things will become slower / more unstable, etc.
And you should not believe what you read on the Internet.
That said: To tell Windows 7 to NOT use of all the cores that are available is mostly for debugging purposes or some kind of developer tests when you want to simulate a system with only one core. Another reason is to work around buggy installers. Turning the cores off otherwise is not of any other use, the limiting factor of the boot process is mostly disk I/O anyway nowadays (so, buy a SSD when you want a blazingly fast boot .. or don't run that many processes upon startup -> less disk I/O as well).
Again: Windows 7 uses all available cores at boot time. The snippet you read on the Internet is most likely the super-über-hack to go into MSConfig and then check the
It LIMITS (as in 'puts an upper limit of used cores') the boot process to take only UP *TO* processors and (this is also important) later on provide only that amount of processors for the OS. If you select one there you will run a system with only one processor.
Yes, you should enable all 4 cores.
I noticed this not long ago, I had an Intel i3 quad core processor, and it was running really slow. I then noticed Windows was only using 1 core. If you go to Task Manager (Ctrl+Shift+Escape), and on the
If they aren't being used, then go to
In Task Manager, it should show all your cores. If it says
This sped mine right up, and it's 4x faster now
EDITOR NOTE: This involves editing the registry, which can screw up your Windows installation if you're not careful. These options are also available by going to Start, typing
