Question High CPU usage on task manager startup

[CrippledPenguin]

I've recently noticed that when I open task manager the initial CPU usage is upwards of 80% and even 100% at times then it quickly shoots down to the normal level of around >10% when idle. This got me a little suspicious as I've never noticed it doing this before and found out this is typical behaviour for a bitcoinminer. I've looked around the internet for solutions and apart from reinstalling windows I've done everything (malwarebytes/rootkitscan, antivirus scan, cmd restorehealth commands etc) and nothing has seemed to work. I've tried to screenshot as much as possible in the task manager which I will include. Just before I post this I noticed that along with the high cpu usage when I open task manager I actually just saw that task manager's power usage also shoots up to very high or moderate then falls with the cpu usage which is making me wonder if it's a bitcoinminer at all. Anyway any solutions are welcome.

Edit: I have also ran HWMonitor and it is showing my cpu usage is at normal levels when task manager isn't open, not sure if it is a miner that can detect HWMonitor too or task manager is at fault here.

click on the cpu column header to sequence the highest cpu usage.

only when you open task manager? it just checking for data.
but do scan for malware

It does down too fast for me to check usage but this is the best image I could get : cpu usage

if it go down. and no malware. there nothing to worry about. find something else to do

That's a normal thing! It's Because task manager is loading all apps, services and apps's icons... Happens to me all the time on any computer...

The first 1-3 minutes of post-bootup activity are often busy with AV scans, starting/syncing of assorted cloud storage accounts, and Windows updates. (THis takes longer with a laptop spinning drive, of course, vs. when using an SSD...
