Windows 10: Constant high CPU usage when idle after upgrade from Win 7 to Win 10

Due to Windows 7 no longer being supported I 'upgraded' my Acer Aspire 5377Z laptop to Windows 10. On completion of the upgrade I noticed that the Task Manager showed constant high CPU. When the PC settles down after power on the CPU usage remains above 50% with no programs running. Task Manager shows almost all of the usage is assigned to Service Host: Device Setup Manager.


The CPU was never this active when idle in Windows 7.

The laptop is fitted with 8GB RAM.

It is fully updated to Version 1909, Build 18363.657.


Help to resolve this issue would be appreciated.


Thanks

High CPU usage at idle after win update, w7

I need a little help please, I have here a Mk6 toughbook, as these have no cooling fan they use the chassis to cool the CPU, I noticed it was running hot and slow, I checked in task man and noticed the CPU usage at idle was fluctuating between 30 - 50%

I ran AV and Malware cleaner, it found a couple of files, they got deleted but still had the same problem (just to let you know this PC is not used with internet connection unless there are updates for the software that's installed)

I fitted a new hard drive and installed a fresh w7, after install I noticed CPU usage was, at idle fluctuating 0 -5%, I installed the toughbook drivers, after each driver install I checked CPU usage at idle and it was how it should be at 0 - 5%

I then installed the w7 updates that the update program found, after complete install and a few restarts my CPU at idle usage is back up to 30% at idle, please can someone help me solve the problem as to why the CPU usage is so high at idle after the w7
updates

TIA

 

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!
