Hello,

You told your version is 1803.

So I suggest you to install 1809 then we will explore furthermore if the issue persists

Answer 2

Hello,

1803 is obsolete ans Symantec protection may cause issues on W10.

Run a scan with your antivirus

Then

Follow the method below to upgrade to Windows 10 version 1809, current version.

Uninstall temporary but completely any third antivirus.

Clean your drive using cleanmgr command in admin mode.

Install Windows 10 version 1809 by downloading it from this page

Anyway, I suggest you uninstall temporarly Symantec and I'm sure you will see CPU usage decrease

Answer 4

Hi Vichet. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.

1. Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

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.

2. Update your drivers from the 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.

3. If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1809 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...

I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
