Windows 11 CPU running at 100% intel i5-8400
Hey,
So i've got this issue for a while now, my processor is at 100% all the time on windows 11.
I have an intel i5-8400, even if i close everything, even on background, it's still at 100, everytime something turns off, another system app take the space (like WMI Provider Host, Windows Search, Anti malware...)
Is there something wrong ? am i missing a driver or something ? or is it just my cpu being too old now ? I just downloaded latest gpu drivers but maybe i should try to re install windows...
I feel like it's affecting my running apps, they feel kinda slow all the time...
Thanks 🙂

If your Intel i5-8400 CPU is consistently running at 100% utilization on a Windows 11 system, it could be due to several reasons, and you may need to investigate further to identify the specific cause. Here are some steps you can take to troubleshoot and resolve this issue:
Check Task Manager:
Open Task Manager by pressing Ctrl + Shift + Esc or Ctrl + Alt + Delete and selecting Task Manager. Look for the processes or applications that are using a significant amount of CPU resources. This will help you identify the culprit.
End Unnecessary Processes:
In Task Manager, you can end any processes or applications that are using a lot of CPU resources and are not essential. Be cautious not to end critical system processes, though, as it can lead to instability.
Update Drivers:
Ensure that your CPU and graphics drivers are up to date. Outdated or incompatible drivers can cause high CPU usage.
Scan for Malware:
Malware infections can cause high CPU usage. Run a thorough malware scan using a reputable antivirus or anti-malware software.
Check for Windows Updates:
Make sure your Windows 11 operating system is fully updated. Microsoft often releases updates that address performance and security issues.....................- Already done what you said, i ran a malware scan with no result, drivers are updated, windows is updated
- Try open start and search for feedback and open the Feedback Hub app and report this issue.
What is the model and manufacturer of your PC?- None, built it myself, my motherboard is an msi and i've 16Gb ram, with this you've all infos on the computer.

Run a full system scan using antivirus software to check the computer is not infected with malware, which can often cause high CPU usage.
Also ensure Windows 11 and all drivers are up to date. Sometimes, outdated drivers or system files can cause compatibility issues leading to high CPU usage.
