Windows 10: High CPU usage at idle. Windows 10 Pro clean install

I've noticed a new clean install of Windows 10 pro consuming up to 100% of CPU, when left idle for a few minutes.Whenever I move a mouse or press a key, a CPU usage isntantly drops to almost 0%.Process responsible for this is "System".I've found similar threads here but no answers nor solutions.

Windows 10 & 11 idle high ssd usage and high cpu usage

My laptop is msi gl65 9scxr (now 6 months old)

• i5 9300h
  
• gtx 1650
  
• 16GB ddr4
  
• 512GB Kingston OM8PCP3512F-Al1 m.2 nvme ssd( shipped with laptop) (contains C drive and D drive)
  
• 512GB addlink SATA ssd
  

I have problem with the high reads and writes in Kingston(windows installed on it) . When not doing anything for like 5-4 minutes laptops all the fans kick up and CPU get 100% and SSD constantly write and read at high usages. it usually writes 20-30 GB every day when idling . If i click mouse or interreact with laptop it goes to normal. if i get the idle process running and it automatically get cool down after some time but it writes and reads GBs of SSD. If i interact with the laptop while that idle usage happening then it starts after when i next time keep the pc idling. It happens everyday when i turn on laptop .I it a pain that SSD also kills it life time ware.

When i get the laptop there was no windows installed to it. So i installed windows 10 to it. After 3 months i try to monitor SSD written TB via crystal disk info. for 3 months its usage was 3.1TB and 98% health. so i concerned it and every day i monitored its activity. so nothing happen it usually high SSD usages. I tried clean Windows 11, upgrade 10 to 11, nothing happens. problem exists.

I tried all methods to save SSD like,

• disable SuperFetch
  
• disable search index
  
• disable automatically windows updates
  
• disable other apps automatically updates
  

etc...

How to slove this problem? This is a pain to me...........

 

High CPU Usage at Idle

Hey guys, recently my W10 PC seems to be using a fair bit of CPU. I noticed this because my Battlefield 1 fps appeared to have dropped. First thing I did was roll back my nvidia drivers to the previous version, but then I noticed my cpu usage. I seem to be using 35-45% cpu usage at idle. I've never seen it go below 35% (In safe mode its around 2-3%).

Things i've tried:
- Sfc scannow at boot (it found & fixed a few things)
- chkdsk /f at boot
- Stuff from here: Windows 10 High CPU Usage Fixes
- Superantispyware scan

Hopefully someone will be able to point me in the right direction!
Thanks!
