Windows 10 Reverts System Date & Time

In Window 10 Version 1511 there’s a new feature called Secure Time Seeding that is part of the Windows Time Service. The feature uses metadata from outgoing SSL connections to set the date & time for a computer. Where this feature has caused headaches in my experience is during mass deployment/imaging. It’s not uncommon for imaging networks to have limited connectivity, specifically a lack of internet access. Due to these networks lacking internet connectivity the computer will end up resetting the date & time to the last known value, which will end up being the date & time that your image was captured.

To resolve this issue you can perform one of the following.

  1. Apply Windows Updates/Inject Updates into your image
  2. Clear the W32time registry values and synchronize via NTP
    To use this method run the commands below via an elevated command promt

net stop w32time
w32tm.exe /unregister
w32tm.exe /register
net start w32time
w32tm.exe /resync /force

  1. Reconnect the computer to the internet/Reconfigure the network for internet access
  2. Disable Secure Time Seeding via Registry
    To use this method run the following command at an elevated command prompt + restart the computer

reg add HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Config /v UtilizeSslTimeData /t REG_DWORD /d 0 /f
