hey recently i am seeing unusual CPU usage on my laptop. On idle sometime my cpu usage spike to more than 50 percent and stays ideally for sometime, if i then try to see what is consuming my CPU through task manager, the usage drops to normal instantly. During the spike CPU temp reaches beyond 85 degrees. It happens occasionally when the laptop is on idle state. What could be causing it?

here you can see that the CPU usage was morethan 50 percent and it instantly droped to below 10 percent when i opened taskmanager to see what is using my cpu…………..if any suggestion please help

    Maybe I am missing something but 1.5GHz is nothing for a CPU with Performance-core Max Turbo Frequency 5.00 GHz, 92°C. max. (peak) is also normal. Check in Task Manager what programs are online and use a lot of your resources. Turn off Turbo Boost.

    @Puraw i am not concerned about the CPU frequency but the usage of CPU on idle. On idle out of sudden the CPU usage jumps to 51 percent which you can see in the above figure and as i try to open task manager to see whats consuming the CPU the usage drops to 2% instantly………..i am wondering what is causing such sudden spike on CPU , also the CPU usage doesnot drop until i open taskmanager to see whats using the CPU

    Uninstall all your 3rd-party AV, browsers, bloatware and trial versions, these programs are all backing up to Cloud, check App History in Task Manager what program used the most of you resouces. Disable syncing for a while to see the impact on your CPU usage.

    hey @Puraw i had 3 browsers installed in my laptop and brave was my default browser, i tried uninstalling it but still i see sudden spikes in CPU usage sometimes and upon seeing the spike i opened task manager and everything went normal.

    on app history i see this but there is nothing to tell me which app used the resource .. Could "Windows Feature Experience Pack" be the culprit as i didnot have this issue before and i had not seen or noticed this in task manager before

    Windows Feature Experience Pack apparently is a W10 relic, I cannot find it anywhere, MS "recommends" not to remove it. it shows up in my app history too, possibly runs only when Windows is updating. Nothing you can do about it. Note that uninstalling browsers and AV programs often leave "agents" lurking in the registry, to completely uninstall a 3rd-party program use their uninstallers in the program folders or to be downloaded from the program sites. Windows uninstaller often leaves the services, tasks, folders and registry keys.

    It might be from some apps checking for updates periodically or the Windows defender automatically scans everything briefly which makes the CPU usage spike up.

    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.
    Thank you and have a nice day!

    hey @AnhEZ28 @Puraw can we create something that can collect logs and register the process in event viewer manually after the CPU usage crosses 50%, as i can see nothing on event viewer during that time also when i have task manager open in background it never happens and when i close it , it starts after a while and when i try to see it through taskmanager process stops instantly as CPU usage drops to below 5%.

    Open Reliability History-Problem Reports that is what MS is using for debugging. Copy the reports to Notepad to read. These will be automatically sent to MS too and you may get fixes with your updates.
