    CPU constantly at 100%

    Being as stubborn as I am for Windows 7, I waited until the last possible second to upgrade to Windows 10. Now that I've upgraded, my CPU is constantly at or near 100% mainly by two processes listed as System and System Interrupts, both running 20-30% each. I looked around and most people say these shouldn't be more than 5-10%.

    Before you start suggesting the obvious like checking for updates, flashing BIOS, upgrading drivers, editing Registry, using Process Explorer, going into device manager, checking background apps, using the built in troubleshooters, formatting, erasing previous Win installations, etc. Let me just say, that I've tried all of those and none of them seemed to work. I can get the CPU down to about 50-60% but that still seems like quite a lot for a freshly booted up PC just sitting on standby.

    At this point, I'm looking for any suggestions at all. My best guess is that maybe my laptops just too old? I've had it for close to 5-6 years or so and I never replaced any of the parts, so it may just be that it's just getting harder to run modern OS? I don't know. If there's any other options, I'd love to hear them before I start looking into replacements.

    Unistack Service constantly at 100% disk usage

    Hello Ruben,

    Thank you for your reply.

    Have you tried check if the issue occurs in safe mode\clean boot?

    If not, I suggest you to follow the steps suggested to boot into safe mode and check.

    If the problem does not exist in safe mode, try to perform a clean boot (from the
    link you have provided) and check.

    Do update us with the status, we are glad to assist you further.
