I receive full functionality even when no program is active, right after the system starts up in Windows. The fans remain unchanged in speed or sound.

It might be a Task Manager issue if that's the situation.

No, I do not adjust the power plan or reduce CPU usage to affect the value.

I referenced my initial comment earlier. Switching the power plan restores the usage to full, yet each time I power off the computer it returns to 100%. Since the programs I use consume a lot of processing power, I don’t plan to reduce the CPU load.

I face the same problem as the original poster. Many people struggle to understand what I’m explaining because it doesn’t make immediate sense... and it doesn’t. I’ve reinstalled Windows several times, updated drivers, adjusted BIOS settings, and more. The CPU in Task Manager shows 100% even when almost nothing is running. We’re dealing with Google Chrome open in the background at full speed. My fan still spins, but other programs indicate low activity. This suggests the system thinks it’s busy, which slows down other tasks. Despite my 15 years in computer networking and repair, I haven’t managed to resolve this. My machine has an i7 4790K. Even though I’ve experienced issues with Skype—once it would reset power plans and drastically improve performance—I still face the same challenge. All apps, until I changed the plan settings, would crash or lag. After extensive troubleshooting, I discovered a bug in the Oculus Rift software. Because VR demands minimal latency, their settings often set IDLEDISABLE to 1. When the headset is off, this setting doesn’t revert to 0, keeping the CPU active and generating heat. This explains the high CPU usage reported by Task Manager. Process Explorer also ignores the System Idle process, showing a lower total than Task Manager. To fix it, run these commands:

```
C:\WINDOWS\system32>PowerCfg /SETACVALUEINDEX SCHEME_CURRENT
C:\WINDOWS\system32>PowerCfg /SETACTIVE SCHEME_CURRENT
```

For details, see my post-mortem.
