Common reasons for this issue include long-running background tasks or problems with the registry after a Windows update. Sometimes, malware pretending to be the service can also cause high CPU usage. Now that you know the causes, lets discuss the solutions.
1. Optimize the Process Manually
Manually optimizing the .NET Runtime Optimization Service helps it finish background tasks more efficiently, reducing high CPU usage. This prioritizes pending tasks, speeding up processes that can otherwise slow down your system, and improves overall performance by completing operations without interruptions.
2. Scan Your Computer for Malware
Malware infections often cause this issue. Conduct a malware check since malicious software can hijack system resources and mimic legitimate files, reducing performance and risking data theft. Use updated antivirus software to scan and remove threats, and keep your system and programs updated to enhance security.
3. Restart the Service
Restarting the .NET Runtime Optimization Service resets it, which can fix problems like high CPU usage if the service gets stuck. Restarting clears any issues, allowing the service to work better. This ensures it starts anew and finishes tasks without delays. An error message might occur upon attempting to start the service: “Windows could not start the service on Local Computer. Error 1079: The account specified for this service differs from the account specified for other services running in the same process.” If this issue occurs, follow these steps to resolve it:
4. Perform a Clean Boot
Performing a Clean Boot can help resolve high CPU usage by starting Windows with a minimal set of drivers and startup programs, which eliminates software conflicts caused by multiple applications and services loading during startup. Follow our clean boot guide, then check the CPU usage. If it has lowered, a third-party application was likely responsible. You can further isolate the problematic software by reactivating applications individually.
