did you try restarting or signing out of your account btw 

Could be just windows being a pain

the problem is that it gets higher without finding any processes, and idk what it could causes this @Ben17

did you wait a few minutes after restarting 

windows often has tasks that run when you first start a pc that can make it go to 100% for about 5 minutes sometimes 

sometimes even when you run a benchmark  the usage will take a few minutes to go down

yeah, i was playing r6, then i closed the application to see if someone needed help on ltt forum and i noticed a loud noise that comes from my pc, the fans were spinning much faster than normal: i checked the cpu usage and it was at 100% usage, i even closed all the application and it was doing a weird thing, going to 4/5% (normal) to 100%, i waited a bit, then I restarted the pc and it did the same thing @Ben17

odd 

I'd leave it sit idle for a few minutes just in case it's windows being a pain tbh 

It's better to be sure than trying to fix a non issue 

sometimes after you have a cpu at high load it takes a while to drop back down again I've found 

usually it's a process called system interrupts that seems to have high usage for a bit

That looks very weird, you could try to run services.msc and disable the print spooler service, see if that helps. (note that you can't print anymore then) Otherwise I would try the usual windows stuff like run sfc /scannow, or see if updating your drivers will help.

So out of curiosity I looked into the windows performance monitor, and it should show you what process is using your CPU. You can run perfmon to open it, then you press the green plus and add process - processor time - all instances. Your graph should show all processes now in real time and you can read what causes those huge spikes by hovering over the lines. In my example the short spikes are from my browser.

okok ill try it, thank you

Would be interesting to know what process causes these spikes that you can't see in the task manager.

I would try to run windows update and see if it fixes it. For some reason antimalware service executable is taking up a lot of CPU, could be normal though I have never looked too closely at it.

antimalware service is defn normal 

I've had that use about 70% in the past before even 

[Ben17]

I'd try just waiting for it to settle tbh @puppo

that process is usually when windows defender (the built in antivirus in windows decides to run a virus scan)

ok so i found some things that i had to download, ill let you know after it finishes the download

Well you shouldn't deactivate it, it scans your computer for malware and makes sure the most recent windows defender is installed.

I would just run Windows Update.
