    moving mouse cause high cpu usage for explorer.exe


    Something strange happens to me i never noticed. When i do nothing i have 1% cpu usage. But when i start rapidly moving mouse, cpu usage goes up to 20% for process explorer.exe, which is indeed weird. And for system interrupts cpu usage increases from 0.1 only to 0.5 How does mouse have to do anything with explorer.exe and i am currently on 4.1ghz intel i7 3770 4 cores, disabled hyper threading. And it doesn't happen randomly tested it already couple times. So weird i don't even have that high polling rate only 500hz and i have connected only mouse and keyboard into top ports of usb 2.0

    :)

    WIN10 1703 update cause Explorer.exe high CPU usage

    I am using Surface Pro 3 (i5, 8G RAM)

    After WIN10 v1703 update, Windows Explorer uses ~30-40% CPU.

    If I uncheck "Show thumbnails instead of icons" in the Performance Options, the CPU usage of Windows Explorer reduces to ~0%

    Any suggestion why showing thumbnails cause so high CPU usage in v1703?

    Thanks!

  3. WIN10 1703 update cause Explorer.exe high CPU usage

    Hi,



    Glad you reached out. First, we would like to know if Explorer.exe
    is the only cause of high CPU usage. Because the common cause of high CPU usage are the following:

    - Windows 10 Memory leak after the update.

    - Driver incompatibilities after the update.

    - Multiple startup applications





    We'll be waiting for your update.

    High cpu usage - CPU Spikes when moving mouse...

    Hi everyone - I've built my own custom pc, it has worked wonders for about 2 years now.

    I've rebuilt some of the pc because of upgrades, so my current specifications is as follows...

    I7-7700k (I JUST replaced this 2 hours ago more on this down below)

    Asus strix 1070 oc

    2x 2400MHz 8GB ram Corsair Vengeance

    Corsair AX 860 PSU

    Asus Maximus VIII Hero Motherboard.

    I have had some problems with my old PCU (I5-6600K) where it had high cpu usage, literally spiking from 10-15% idle to 60-70% just by hovering over icons on the desktop. Also running a steady 100% whenever
    I used any programs.

    Did a bunch of testing to figure out what was wrong with it, but gave up in the end after about 8-10 hours of work on it. Decided to buy a new CPU to see if that helped (i already wanted a new one so i thought
    why not...)

    The problem that is happening was not persistent after I put the new cpu in today. But after about 2 hours of run on the pc it began having troubles again. It first began while playing world of warcraft. The
    FPS was lowered even though both cpu and gpu was running on about 50-80% power. Whenever i would move the mouse my game would just lag out and if i kept moving it continuously it would completely stop showing frames and just freeze until i stopped moving it
    again.

    After that i noticed that whenever i moved my mouse on the icons on the desktop or move my mouse around on google chrome it begins spiking up again like last time. Also it uses a lot of CPU power for small
    jobs which it really shouldn't. Like having discord, 5 pages of chrome and steam open it can use around 30-40% on a i7-7700k??

    I know you like when people try to do it themselves first. And I am not a 'noob' at troubleshooting and googling my way through problems, but this one is a tough nut to crack.

    Problem: High cpu usage overall and high cpu spikes whenever i move the mouse. Literally can't play games because whenever i have to move the mouse it begins to do lagspikes.

    What i've tried so far:

    • Reinstalled windows 10 3 times and updated all drivers afterwards.
    • Wiped the entire SSD with the windows 10 and the games on twice.
    • Reapplied thermal paste and even replaced the cpu to a newer and stronger edition
    • uninstalled various drivers from the device manager and reinstalling them.
    • Fiddling around in safe mode without much knowledge of what to look for.
    • benchmarked the cpu to see if it was lacking behind (it wasn't)
    • Done a malware system scan through malware bytes
    • Done a ccleaner scan
    • done a antivirus scan through avira.
    I am out of ideas and i cant seem to find any help on google and i really hope any of you guys are able and willing to help me with this pesky issue... It's not fun to have a 'strong' computer if it can't even
    handle browsing or simple games...
