If you still get the time sync failed error message, you can try forcing the time sync via the command prompt. This will force Windows to sync the time immediately.

1. Type Command Prompt in the Windows Search. Next, 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

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

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

Repair the Corrupted System Files

That’s it! The above commands will find and replace all 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.

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