[CPU shows 100% when opening Task manager]

Thank you ! the other forum made things a lot clearer to me

[CPU shows 100% when opening Task manager]

So sinds a few weeks i've begining to notice that whenever I open the task manager it shows 100% cpu usage for like a second and after I keep it open it goes down to a more normal %. I was just curious if this is normal or if there maybe could be  wrong with my pc. In the screenshots ive uploaded u can see what it looks like whenever I open taskmanager and it just shows that for like 1 second and after that it goes to like 50 % and after that to a normal 10 - 15 %. Ive runned malwarebytes multiple times but it doesnt detect any malware on my pc
