Understanding Windows 11 22H2 Power Plan Issues

Key Points

• Potential Issue with Windows 11 22H2:

  • Users with Intel's 12th and 13th generation processors may experience issues with CPU utilization.
  • Windows 11 22H2 predominantly utilizes performance cores, neglecting efficiency cores unlike Windows 11 21H2.

• CPU & Power Plan Changes:

  • Windows 11 21H2 seems to distribute tasks properly between performance and efficiency cores.
  • The default values of the power plans have changed between Windows 11 21H2 and 22H2.
  • Windows 11 22H2 demonstrates a different default setting in the heterogeneous policy and effect, affecting the core utilization.

• Diagnosis and Solution:

  • Custom power plans can adjust Windows 11 22H2 to function more like Windows 11 21H2.
  • Changing the heterogeneous policy and effect setting from 0 to 4 enables the use of efficiency cores again.
  • Around ten existing fields' values were changed and ten new fields were added in power plan templates.

• Custom Power Plans:

  • Power plans exported from Quick CPU can be used for better performance.
  • Importing steps include downloading the zip file, extracting to a folder, and running the power plan batch file with admin rights.

• Additional Notes:

  • In Quick CPU, setting the heterogeneous policy and effect to 1 can improve system responsiveness.
  • No official Microsoft documentation available for these specific changes.
  • Windows 10 users will not notice a difference as it treats all cores the same.

• How to Handle Imported Power Plans:

  • Users can delete unwanted imported power plans through power settings.
