How can I see the process that brings my PC to a crawl?

    How can I see the process that brings my PC to a crawl?

    I'm coming here with the hope that I'll get this Windows problem solved, since I turned the internet up and down searching for a solution and it was all useless.
    There are times when my PC is unsuable due to 80-99% CPU (some rare times Disk usage).
    Task Manager shows this high consuming but the processes' percentages add up to 50-60%.
    The same goes with Process Explorer.
    What process takes up 40%? The difference never drops under ~10%!
    Can anybody help? Please? What tricks can I do to get the culprit? What solutions are out there?

    What version of Windows are you on? Wonder if this is the same as my issue. It only happens every so often (2 to 3 days) and doesn't last long but i can't right click on Taskbars or anything

    It happens as you say, @AntJac. But this is another story which I've learned to live with. Indeed, there are random times when the system simply halts any activity, allowing only the cursor position to be updated. No spikes in CPU or Disk I/O and this is what is frustrating. BTW this cursor thing changed in update 1709; now the cursor update priority seems equal to that of the UI (progress bars).

    Back to the matter at hand:
    Every time any CPU demanding application runs, it looks like the CPU load doubles.
    One part is reflected in the app percentage as expected and there's another part which adds to that unknown difference. It's as if something outside the system bears the hardest burden of that application or extra burden, leaving the application itself with a reasonably high load.

    So how can we know what is responsible for the said difference?
