Windows 10
Right click on the Start Menu Button and another menu appears. Click on either Command prompt or command prompt (Admin) to open the CMD window.
Step 2) Run gpupdate /force
Step 3) Restart Your Computer
When the update has finished, you should be presented with a prompt to either logoff or restart your computer. Press N to reject those prompts and then manually restart your computer. It's best to completely restart the computer, and it is slightly faster to reboot manually than to reboot through the Command Line window.
Sometimes you will not be presented with a prompt to restart or logoff after the update. However, you should still restart your computer unless otherwise instructed by IT.
