Step 1. Click on the Windows button.
Step 2. Click Restart/Reboot
You will be prompted with a menu to choose the reason for the restart. We just choose Application Maintenance (Planned) usually. It doesn't matter which you plan as this is just for logging purposes.
You will then be asked to Continue to confirm the restart. Once you click it, the server will restart. The server will be back online within 20-30 seconds and you'll be able to connect again.
