Your computer is slow and CPU usage is stuck at 100%
High CPU usage means one or more processes are using up all your computing power. Open Task Manager, find which one, and stop it. This takes 10 minutes.
When CPU usage is above 80%, something is monopolizing your processor and freezing everything else. Task Manager shows you exactly what's consuming the power. You can disable, uninstall, or just stop the process, and your computer should run normally again.
