If your comupter is often de-syncing it's time, you've probably tried running:

w32tm /resync

However, if you're here, you've gotten the following error:

The following error occurred: The specified service does not exist as an installed service. (0x80070424)

Open a new command prompt with Run as Administrator and do the following:

1. register the service: w32tm /register
   • If you've previously done this, it might be a good idea to run w32tm /unregister and then w32tm /register
2. start the service: net start w32time
3. synchronize time: w32tm /resync
