The date and time set on your Windows PC are crucial. Apps use this information to serve you information, reminders, timer apps depend on it, etc.

Sometimes, those services may not function properly because the Windows System clock is out of sync. When the system clock is out of sync, you may see an incorrect date and time and an error message that reads ‘Time Synchronization failed’.

Why Windows Time Failed to Sync?

Several reasons can cause the Time Synchronization to fail on Windows. Below are the most common reasons.

  • Incorrect Time & Date Settings.
  • Viruses or Malware Infection.
  • Problem with the Windows Time Service.
  • Incorrect Firewall Settings.
  • System File Corruption.
  • Problem with the CMOS Battery.

If you’re experiencing issues with the Windows Time sync, you should do these troubleshooting.

1. Check the Date & Time Settings on Windows

The first thing you should do is ensure that the date and time are set to update automatically. Here’s how to check your Windows PC’s date and time settings.

1. Launch the Settings app.

4. Enable the toggle beside Set time automatically.

5. Scroll to the Additional Settings section and click Sync Now.

2. Change the Time Server

The next best thing you can do to fix the time sync failed issue is to change the time server on Windows 11. Here’s how you can change it.

1. Open the Date and Time settings option from the Windows Search.

3. Select Internet Time.

4. Click Change Settings.

5. Click on the Server drop-down and select time.windows.com. Click Update Now.

3. Restart the Windows Time Service

The Windows Time Service should run constantly in the background. If this service is experiencing any problems, time sync will fail and lead to errors. You can try restarting the Windows Time Service and see if it helps.

1. Press the Windows Key + R button on your keyboard. This will open the RUN dialog box.

RUN dialog box

2. Type services.msc and press Enter.

services.msc

3. Find the Windows Time.

4. Right-click on Windows Time and select Start. If it’s already running, right-click and select Stop and then Start.

Start

4. Add More Time Servers

Adding more time service may fix the time sync failed error on Windows. If you add more time servers, Windows will try different servers to keep time in sync.

1. Type Registry Editor in the Windows Search. Open the Registry Editor app.

Registry Editor

2. Navigate to this path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers

navigate to this path

3. Right-click the Servers and select New > String Value.

New > String Value

4. Name the new String value anything you want, for example, Server new, Server 3, etc. Double-click on the String value. In the value data field, type time.google.com and click OK.

time.google.com

5. Force the Time Sync with CMD

If you still get the time sync failed error message, you can try forcing the time sync via the command prompt.

1. Type Command Prompt in the Windows Search. Right-click on the CMD and select Run as administrator.

Run as administrator

2. When the Command Prompt opens, execute these commands one by one.

net stop w32time

w32tm /unregister

w32tm /register

net start w32time

w32tm /resync

net stop w32time

After executing all commands, close the command prompt and restart your Windows PC. This will force Windows to sync the time.

6. Run the SFC and DISM Command

System file corruption could be another reason Windows fails to sync the time. You can find and replace the corrupted system files by running the SFC and DISM Commands.

1. Type CMD in the Windows 11 Search. Right-click on CMD and select Run as administrator.

Run as administrator.

2. Execute this command:

sfc /scannow

sfc /scannow

3. If the SFC scan returns with an error, execute this command:

DISM /Online /Cleanup-Image /RestoreHealth

Repair the Corrupted System Files

7. Disable any Firewall or Third-Party Security Program

Firewalls and third-party security apps that you may use can prevent the Windows Time service from running and create issues with the time sync.

If you’ve recently added a firewall protection or security app, you can temporarily disable it and check.

8. Run a full antivirus scan

Malicious softwares can sometimes interrupt the time sync process and trigger errors. So, if all other methods listed above have failed to fix the time synchronization issues, it’s time to scan for malicious programs.

1. Type Windows Security in the Windows Search. Next, open the Windows Security app from the list of best-match results.

Windows Security

2. Switch to the Virus & Threat Protection.

3. Click Scan Options.

4. Select Full Scan and click Scan Now.

Full Scan

The Full Scan may take a while to complete, so be patient. Once the scan is complete, restart your Windows 11 PC and check whether you still get the error.
