  2. 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.

  3. 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 AdministratorWon't boot after changing number of processors in msconfig :(F) /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?

  4. Won't boot after changing number of processors in msconfig

    Number of Processors in MSCONFIG

    Ok, so i'm tweaking with my OS, and i opened up msconfig. I noticed that under Number of Processors, it shows I have 16. I only have an 8-core processor. What would happen if i chose 8 or 16? Would i get a faster boot time?
