Intel Gives Core i3 and Core i5 Dual-Core Processors K0 Stepping Update

Intel is giving some existing 32 nm "Clarkdale" based Core i3 and Core i5 processors an update. The processors will transition to the new K0 stepping from the existing C2 stepping. The parts that will be made on the K0 silicon are Core i3 models 530 (new sSPEC: SLBX7), 540 (new sSPEC: SLBTD) and Core i5 models 650 (new sSPEC: SLBTJ), 660/661 (SLBTK/SLBTB), 670 (SLBTL). Newer and upcoming models such as the i3-550, i3-560, i5-665K, and i5-680 are already being built on the K0 stepping die. Motherboards will require a BIOS update to support the new K0 stepping processors.

The K0 stepping change includes the following highlights:

• New S-spec and MM numbers for the converting products
• Extended CPUID will change from 0x00020652 to 0x00020655
• Host RevID will change from 0x12 to 0x18
• K0 stepping package is pin compatible with C2 stepping package
• Adds Processor Context ID (PCID) support

The revised older SKUs that are built on K0 stepping will be market-available by October 16.

 

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?
