Is your Windows theme not syncing properly? Here is the solution

Themes are a great way to customize the overall look of your operating system. It’s pretty easy to set up a theme in Windows, but you might run into some issues doing it.


In Windows, users often encounter problems synchronizing themes. Below we have discussed the possible causes and solutions for this problem.


Why can’t the Windows theme sync itself?

If the Windows theme is having trouble syncing, here are some causes:

  • Your Windows operating system is not configured to remember the preferences you set. This setting must be enabled in the Accounts section of the Settings app for the changes to take effect and remain.
  • Generic corruption error can infect the system which can lead to minor issues like the one occurring. You can perform a system scan using Microsoft’s built-in troubleshooting tools to resolve this issue.
  • The SettingsSyncHost.exe may not work properly. You can simply restart this service using the Task Manager to fix the problem. We have discussed the steps for this in detail.
  • There may be a problem with the theme you are trying to use. It may be incompatible with your system or simply corrupt, which is why it cannot sync.

After discussing the possible causes of the error, let’s take a look at the troubleshooting methods that can help you fix it.

1. Check if the theme itself is causing problems

The first thing to try is to check if the theme you are trying to sync is the cause of your problem.

In some cases, the users got into trouble because their theme was incompatible or corrupt. To determine if this is the case, you will need to download and use a different theme. If the theme implements itself successfully, that means the one you were using before was problematic.

2. Restart the SettingsSyncHost.exe service

If the theme itself is not problematic, then the next thing to do is to restart the SettingsSyncHost.exe service using the Task Manager.

This service is responsible for synchronizing the system settings with your devices. If the SettingsSyncHost.exe process is not working properly, you are likely to encounter errors like this one. Fortunately, however, a simple restart can fix the problem in most cases.

Here’s how to restart the SettingsSyncHost.exe process:

  1. Type Task Manager in Windows Search and click Open.
  2. Go to the Processes and find the process “Host process for settings sync”.
  3. Right click on Host process for settings sync and choose End task from the context menu.
  4. When you are done, restart your PC. After reboot, the service will restart automatically. You can then try resetting the targeted theme and check if the issue is now resolved.

3. Make sure the sync function is turned on

In addition, you may experience this problem because the Windows synchronization feature is disabled. With this feature turned off, Windows won’t remember your preferences, causing issues like the themes not syncing.

Here’s how to turn the feature back on:

  1. Press To win + I keys together to open Windows Settings.
  2. To elect bills from the left pane.
  3. click on Windows backup.
  4. Find the Remember my preferences option and turn on the switch for it.

Once done, you can close the Settings window and check if you are still experiencing the issue.

4. Enable sync with Registry Editor

You can also force-enable the sync feature using the Registry Editor, an administrative tool.

If you don’t already know, the Windows registry is a database of information about Windows programs and processes. The information here is stored as keys and values, which can be modified to make the changes you want.

To continue with this method you will need administrator access to the system. If you are using a standard user account, switch to the administrator account. We also recommend that you create a registry backup before proceeding just in case.

When you’re ready, follow these steps:

  1. Press To win + R to open Run.
  2. Type regedit in Run and press Ctrl + Shift + Enter to start the registry as administrator.
  3. In the Registry Editor, navigate to the location below:
    HKEY_LOCAL_MACHINE/ SOFTWARE/ Microsoft/ Windows/ CurrentVersion/ Policies/ System
  4. Go to the right side of the window and right click on an empty space.
  5. Choose the New > DWORD(32-bit) Value choice.
  6. Rename this key as No connected user and double click on it.
  7. Type 0 under Value data and click Enter.
  8. Once done, close the Registry Editor and restart your PC.

On reboot, check if you can now successfully deploy the theme.

5. Scan the system for corruption

As we mentioned before, in some cases the error was also caused by system corruption errors that caused the sync function to work.

The best way to identify and fix such corruption errors is to scan the system using Microsoft’s built-in troubleshooting tools. The two tools we recommend in this case are the System File Checker and DISM.

You can run both tools using Command Prompt. They will scan the system for possible errors and fix the identified errors without requiring any input from your side. Make sure you have administrator access to the system to continue.

You can learn how to run both scans in our article on the differences between CHKDSK, SFC, and DISM. The scans may take a while, so wait for the process to complete.

Successfully sync your Windows themes

Now that you know the possible causes and the solutions to the problem, you can successfully apply the themes. Make sure to only download themes from trusted websites when installing them online. If you don’t, you may install a corrupt theme that has a negative effect on your system as a whole.
