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 Administrator:(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?

  • What happens if you patiently wait for "Attempting Repairs" to complete or to announce failure? – harrymc Jul 5 '19 at 19:44
  • I wait patiently (don't cancel or anything like that) and receive the message "Your PC ran into a problem and needs to restart. We'll restart it for you". It restarts automatically, then I get the Windows Automatic Repair screen with two buttons: Shut Down or Advanced Options. – user3138025 Jul 5 '19 at 20:35

I kept looking and found a solution. When in Windows Automatic Repair, I open the Command Prompt and type the following two commands:

  1. bcdedit/deletevalue {default} numproc
  2. bcdedit/deletevalue {default} truncatememory

Don't substitute anything for "{default}". That's how it's meant to be entered. I rebooted and it fixed my problem. I found this solution in the link: https://blog.pcrisk.com/windows/12554-how-to-fix-badsystemconfiginfo-error
