Date reverts to current one in Windows Sandbox

Posted on


I’m unable to change the current date in Windows Sandbox. I have disabled “Set time automatically” from the settings panel and I’m able to change the date, but 1 or 2 seconds later the date reverts to the current one.

This seems to be an issue similar to Changing Windows 10 System Clock Doesn’t Work but I don’t know how to disable time synchronization for Win Sandbox.

Does anyone have any idea about how to keep this from happening?


OS Name:                   Microsoft Windows 10 Pro for Workstations
OS Version:                10.0.19041 N/A Build 19041

This is not the perfect answer to this problem, But if you want to run software on a different date and time you can use RunAsDate application. This app is allowing you to run a specific software at different times and date and it works great on Windows Sandbox.

You need stop (and possibly disable) the Windows Time services from the Windows Services manager.

Start > run > services.msc

Look for Windows Time

Right-click and Stop or
right-click and go to Properties, then change the Startup type to disabled.

Very crude, but seems to work. Copy/paste into Powershell ISE

for ($num=1; $num -lt 9999999999; $num++){
sleep -Milliseconds 500
set-date 12/22/21

Adjust timing as needed.
