This approach will fix the excessive CPU consume by updating your PC and your PC will return back to normal. You can restart your PC, check your device task manager to confirm it.

There is no need to try the second approach if the above works for you. But, whichever method you prefer, you will achieve the same result which is fixing Windows 10 high CPU by Windows installer worker.

Ethernet Network Connection

This is the final approach. If you are not using WiFi hotspot, then, it means you are using an Ethernet network connection.

We have also found a workaround to fix the Windows 10 high CPU due to Windows installer worker activities.

1. Press and hold the Win icon + R on your keyboard together at the same time to pop up the run box.

2. Type regedit into the box and then click on the OK button to open your Windows reg and edit interface.

3. You will be prompt by your Windows User Control. Just click on the Yes button to proceed.

4. Then, proceed like this: KEY_LOCAL_MACHINE > SOFTWARE > Microsoft > WindowsNT > CurrentVersion > NetworkList > DefaultMediaCost

5. Now, right-click on DefaultMediaCost and select permissions… from the popup.

6. From the popup click on Add >>type server name >> check the server name >>OK.

7. You have to proceed by clicking on just added and the allow full control by ticking allow.

8. Double click on Ethernet. Set it to 2. Set based to Hexadecimal and click OK.

After the above steps close the Regedit window and save all task. After that, restart your Windows computer and try to check the issue again after it has rebooted successfully.

The first approach is probably the easiest, followed by the second approach (WiFi hotspot) and finally by the third approach (Ethernet network).

Irrespective of the approaches, they all end to the same result. I’d advise you try the first step or second before going to the 3rd steps because of the long process.
