High CPU usage in state repository service after clean install of Fall Creators Update while online via ethernet

Finally, after a couple of hours of searching and digging, I solved this problem.

Some really help to run the command in PowerShell under the administrator:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

or perform a reset and repair MicrosoftEdge in Settings but  not for me.

After a long digging, I noticed that during the boot, messages appear in the system log

Win+R -> eventvwr -> Windows Logs -> System

Similar content:

The application-specific permission settings do not grant Local Activation permission for the COM Server application with

CLSID {D63B10C5-BB46-4990-A94F-E40B9D520160}

and APPID {9CA88EE3-ACB7-47C8-AFC4-AB702511C276}

to the user NT AUTHORITY*SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.*

And I decided that this is probably related.

For fix this error, you need to find this APPID in the registry

Win +R ->regedit

There should be 2 entries

1 

And 2

Everyone needs to get the right to change, I needed to change the owner to "Administrator". After all, you will probably need to restart your computer.

After you need to find this application in DCOM Config

1. Open Control Panel -> Administrative tool.
2. Open component services.
3. Click Computer, click my computer, then click DCOM.
4. Look for the corresponding service that appears on the error viewer.
5. Right click on it then click properties.
6. Click security tab then click Add User. Add SYSTEM then apply.
7. Tick the Activate local box.

In addition to the SYSTEM user, I needed to add LOCAL SYSTEM. Maybe you have someone else you need to add.

After I cleaned and reset Microsoft Edge and rebooted.

I hope this helped

Yes, I did but it didn't solved my problem and after that I did a clean boot it also didn't solved my problem.

I'm going to tell you what I think about this issue.

If you upgrade your window from 1703 to 1709 the problem will not occur everything works fine but after upgrading your pc if you reinstall your window State repository service will make cpu reach 60% usage everytime you try to open a link in Micorsoft edge and thus because of this PC start's lagging.

PC SPEC,

Core I 5 7600k

Z170x gaming 7 motherboard

graphic card GTX 1070

240GB SSD

2TB harddrive.

The problem is this happens clean install, so nothing is loaded outside of what the installer provides during a clean install.  For me this included formatting the drives entirely.

We're presented with a fresh desktop, a window of Edge open and nothing else.   The only way I noticed it at first is Edge was seemingly frozen presenting "<webpage> is not responding" errors on multiple domains that I tried.   

I have 3 clean install machines that do this exact same thing.   In addition, each machine was tested with different keys created by the windows download tool, several times to ensure it wasn't a bad install.

I contacted support via the built-in tool, they couldn't find an issue and ultimately gave me a different W10 FCU iso to write and install again, same issue. 

TL;DR - The clean boot idea has been tested extensively via clean installs, to no avail.

I'm also facing the same issue literally installed my window 3 time because of it and state repository service is still making my cpu usage to reach 50% My Microsoft edge hanged 2 times when I was writing this and it literally took 20min to upload this message. Please fix this issue everything is just too slow because of this.
