If you want to force Group Policy Update in Windows 10, you will have to make use of the built-in GPUPDATE.exe tool. This tool lets you refresh Group Policy manually.



By default Group Policy gets updated in background every 90 minutes, after a change is recorded in active object. But you can change the Group Policy Refresh Interval or refresh it manually.

To run this tool, open an elevated Command Prompt, type the following and hit Enter:

gpupdate /force

After this, you will see the following message:

Updating Policy...User Policy update has completed successfully.Computer Policy update has completed successfully.
