Windows 10: Question about Number of Processors in Advanced Boot Options

Hi there. So I recently upgraded my os system to Windows 11 and I saw many people taking about changing the number of processors to the number to cores on the processor in advanced boot option. And some advised against it. So I was wondering should I change it to the number of cores of my processor? And even if I do that, will I get better performance?Also how can I decrease the brightness in my Windows 11 desktop?

Boot Advance options processor/memory settings

This is an interesting capability. Turns out this is provided to help troubleshoot issues in using multiple processor(s, or cores, most likely) during boot. By default, all Processors/Cores are enabled. So if you exercise this option, it can only be to REDUCE CPU capabilities. This is one of those "best left alone" settings, IMO -- though you can play with it if you like. Here are some hopefully useful items/discussions on this topic:
1. If I enable 2 processors in msconfig, will it increase my computer - Microsoft Community
2. cpu - Msconfig - Number of Processors - Super User

Windows 10 fails to start after setting number of processors in advanced boot options

Hi Al,

I did something stupid and can no longer get into my computer....

I have a hp elitebook 8760W with 16GB of RAM. When doing renderings, I noticed that it never uses more than 4GB of memory, even when all 4 cores (8 logical processors) are maxed out at 100%.

Googling the topic, I came up with a suggestion of going into advanced boot options and checking the memory checkbox, forcing the use of 16GB rather than unchecked (auto).

While there, (and here comes the stupid part) I also checked the number of processors checkbox. Not knowing if it refers to physical processors, number of cores or logical processors, I went "safe" and selected 1.

The computer rebooted fine, but on running task manager again, it revealed that I was still running less than 4GB RAM and now only one processor, instead of 8. So back I went and unchecked the checkbox for the number of processors. All subsequent attempts
to boot into windows failed and all I get is a blue screen with:

your pc ran into a problem and needs to restart. We're just collecting some error info, and then you can restart. (100$ complete)

if you'd like to know more, you can search online later for this error: BAD_SYSTEM_CONFIG_INFO

I also tried restoring to a previous restore point, by that failed as well.

Any help or advice would be much appreciated.

Boot Advance options processor/memory settings

Thanks for that ED, I find it confusing from info I find on the computer i.e.
Top left, I could read that as I have 8, 8core processors? WOW!
Top right, "number of processors" (mother board with 8 processors?) when they actually mean "cores"? Logical/cores not mentioned.
W10 insider info, I find this to be the best info, I have an 8-core processor
From task manager, 1 socket (1 physical processor), but I only have 4 cores and 8 logical processors.

What first started me looking for this was, task manager was showing only 1 cpu. Later found out that clicking on the graph itself (instead of a menu somewhere on the top??) that I could change it to view all cores.

Sometimes you must work thru the mess and figure out what is the true meaning*Confused
