Ok so. Few days ago I bought a new laptop. I went to mconfig to see how many cores I have activated. I only had one so I upgraded it to 4/8. Later I returned it to normal to test something. Today I decided to put it back to 4 again but for some reason it says I only have 1 core. Can you please help?
Hello and welcome to the forum. You are confusing processors and cores. You only have 1 processor. That processor may have 4 cores but it is only 1 processor. None of those boxes should be checked. That is to limit resources only. Windows will, by default, use all cores and all ram to boot.
Oddly enough, I found the following: https://www.vistax64.com/threads/boo...essors.153125/
I admit it's for Vista, and posted in 2008, By someone using the handle Brink. Apparently you can choose the number of "processors" used during boot. (In Device Manager, cores, including the virtual ones, are listed as processors.)
I admit I'm confused by the article. Does changing the setting affect the number of processors available to Windows, or just the number used during boot?
For the OP: speaking of Device Manager, how many processors are shown there?
I don't know about processors/cores. I have always read the description of the option which says processors. By definition The processor is the CPU which most of us only have 1. So, I have always assumed you can select how many cores are used. If Windows uses all available cores by default, the setting can only be to limit the number for debugging purposes. It has to be counting cores.From the tutorial you linked to.
Note
Vista will use all your processors by default at boot up without this Number of Processors setting box checked. Using all of your available processors (cores or CPUs) durring boot allows the computer to boot faster only because a multiple core CPU or multiple CPUs can handle and do more at once than a single core or CPU. Multiple cores do not actually increase the speed, but only increase the number of processor cores working on the job which in turn has the job finish quicker. If you do not have much running at startup, then you may not notice much improvement in how long it takes to startup.

This is from the Windows 7 Tutorial
Information
If you have a multiple core processor (CPU) or multiple processors, then this will show you how to limit the number of processors to be used by Windows 7, or to make sure that you are using all processors.
This can be handy for troubleshooting and debugging purposes to be able to determine if there is a problem with a single processor/core, or for a programmer to test their code against a single core while still running on their multi-processor/core system.
Windows 7 uses all of your processors or processor cores by default.

So it does control the number of processors available to Windows. I hope that I never need to remember that.This is from the Windows 7 Tutorial
