Windows 10: I changed the number of processors in the msconfig settings, and I'm experiencing lags in...

Hi everyone, recently I encountered an issue with msconfig on my Acer laptop. Everything was working fine until I changed the number of processors from 1 to 12. After that, I went into Roblox as usual, and I started experiencing screen tearing. I reinstalled Windows, and the screen tearing disappeared, but minor lags were still there. I updated the drivers, installed a new BIOS, and reinstalled Windows again, but nothing helped. I'm curious what the problem might be. The processor is an Intel Core i5-13400F. I'm waiting for a response, but I kindly ask you to write in simpler words, as I'm fro

Can't fix MSCONFIG Processor setting after changing number of processors to 8

I'm using Windows 10 Pro.
I was looking for ways to increase performance and I came across some postings on MSCONFIG. I navigated to the option Boot/Advanced Options/Number of Processors. When I checked it, I saw that I could change the number from 1 to 8. I did so and rebooted. Now, when I boot I get in an endless loop of Windows Automatic Repair telling me that I have a configuration error and "Attempting Repairs". I'd like to change the Processors back from 8 to 1.
When I choose Advanced Options \ Troubleshoot \ Advanced Options I receive a menu of choices.

• Menu Options
  
• When I select "System Restore \Restore Point" for a few selections I get the message "System Restore did not complete successfully. An unspecified error occurred during System Restore. (0x800070003)"
  
• When I select "Go back to the previous version" I receive the message "We ran into a problem and won't be able to take you back to the previous version of Windows."
  
• When I select "System Image Recovery" I receive the message "Windows cannot find a system image on this computer."
  
• When I select "Start Repair" I get an error with that as well.
  

I've also taken the following steps already.

• Other Steps:
  
• Windows with Command Prompt (It Boots from drive X", and the
  original drive "C" is now "E")
  
• net user administrator /active:yes
  
• CD E:\Windows\System32\config MSCONFIG (I Receive the error: "You do
  not have sufficient privileges to run System Configuration. Please
  run this utility as a user in the Administrators group."
  
• CD
  E:\Windows\System32\config ICACLS E:\Windows\System32\config*.*
  /INHERITANCE:r /GRANT:r AdministratorF) /F /C
  
• Regedit
  
• (I point to
  HKEY_LOCAL_MACHINE)
  
• File / Load Hive
  
• (I Navigate to)
  E:\Windows\system32\config\SOFTWARE
  
• Open
  
• (I receive the message
  "SOFTWARE You don't have permission to open this file. Contact the
  file owner or an administrator to obtain permission")
  

How can I change the number of processor settings when I'm in Windows Automatic Repair?

 

Changed number of processors in msconfig

Hi , I went into the msconfig menu and selected Boot-Advanced and proceeded to turn the number of processors down to 7 from 8 and then decided that I was a genius and made boot settings permanent and now cant change it back. What effect will this have
on my PC and should I change it back and how?? Thank you.

 

Changed number of processors in msconfig

Those settings are only for testing and not setting number of processor cores. Your number of processor cores is fixed in Task manager on Performance tab.

This video explains what must be done to undo making boot changes permanent:



I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
