If that isn't enough go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue
with the other steps to go over your install most thoroughly.

Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed
in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the latest
version.

Services and Controller app causing 100% CPU Usage

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that Services and Control app is causing 100% CPU Usage. I’ll help you with this issue.



Upon researching, I found that few of our customers were also facing High CPU usage with Services and Controller app and this was caused by an application named “Segurazo”, which turns out to be a third party anti-virus software.



They were able to resolve the issue by uninstalling the application. I would suggest you to refer the suggestions by

cpu usage at 100%

CPU usage at 100% from start up for no apparently good reason. Service Host appears to be the problem but I cant narrow it down more than that at present.

Any suggestions?

I am using Windows 10 full release version 64 bit.
