Host process for Setting Synchronization (SettingsSyncHost.exe) causing High CPU usage

SettingsSynchHost.exe process runs in the background that ensures there is a continuous synchronization between the host device (your device) and client devices (your other devices). If you are seeing SettingsSyncHost.exe is eating up too much of the CPU power, there is nothing to worry about. This issue may be triggered due to corrupted Windows Updates that your device has recently received.


Fix 1 – Disable sync settings

Disabling the synchronization settings should fix the issue on your computer.

1. At first, press Windows key+I.

2. Then, you have to click on the “Accounts” settings to access it.


Settings Accounts


3. On the left-hand side, click on the “Sync your settings“.

4. After that you need to toggle the ‘Sync settings‘ to “Off“.


Sync Settings Off


Close the Settings window.

You may reboot your device. After rebooting the device the ‘SettingsSynchHost.exe’ process won’t eat up huge CPU power.


Fix 2 – Run a PowerShell code

Running a PowerShell code automatically to stop the specified service every 5 minutes should fix the issue.

1. Press Windows key+X.

2. After that, click on the “PowerShell(Admin)” to access the PowerShell.


Start Right Click Windows Powershell Admin


3. When the PowerShell opens up with administrative rights, type this code there and hit Enter.

Register-ScheduledJob -Name "Kill SettingSyncHost" -RunNow -RunEvery "00:05:00" -Credential (Get-Credential) -ScheduledJobOption (New-ScheduledJobOption -StartIfOnBattery -ContinueIfGoingOnBattery) -ScriptBlock { Get-Process | ?{ $_.Name -eq "SettingSyncHost" -and $_.StartTime -lt ([System.DateTime]::Now).AddMinutes(-5) } | Stop-Process -Force}


Powershell Code


As soon as you hit Enter, you will see a panel has opened asking for your credentials.

4. Enter your username. Put the account password.

5. Finally, to register the job in your device, click on “OK“.




This will kill the SettingsSynchHost.exe process on your computer.



Stopping the SettingsSynchHost.exe process will pause the sync between your devices. To deactivate this code, you have to execute these steps-

a. Acess the PowerShell terminal again.

b. Then, copy-paste this code and hit Enter to un-register the job.

Get-ScheduledJob | ? Name -eq “Kill SettingSyncHost” | Unregister-ScheduledJob


Code Deactivator


Close the terminal and restart your computer.
