Question

Issue: How to fix missing System Cooling Policy in Windows?

Hello. The System Cooling Policy is missing from the Power Options settings on my Windows PC. Is there a way to fix this?

Solved Answer

System Cooling Policy is a setting in Windows that allows the user to control how the system manages cooling when it is under heavy load. People might use System Cooling Policy to control the noise level of their computer or to extend the life of their components by reducing wear and tear on cooling systems. Some people also use it to save energy. The options available are “Active” and “Passive.”

  • Active – means that the system will use cooling methods like fans to cool down the system when the processor is working hard.
  • Passive – means that the system will rely on natural convection to cool down the system.

The System Cooling Policy setting may be missing from Power Options in Windows due to a variety of reasons such as a change in the settings made by another program or Windows update, or the setting may not have been enabled by default.

People can add the System Cooling Policy setting in Windows by editing the registry[1] or running a command prompt. However, it is important to note that editing the registry can be risky if not done correctly and it is recommended to make a backup of the registry before making any changes. You can follow the detailed instructions in our article How to back up and restore the Windows registry? to back up the registry and recover it in case something goes wrong.

Access geo-restricted video content with a VPN

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
