Windows Updates

This guide shows how to configure Windows Update on Windows Server 2019, 2022 and 2025 so that your server receives security updates without unexpected reboots. You choose an update strategy and install updates in a planned maintenance window.

These instructions apply to Windows Server 2019, 2022 and 2025 with Desktop Experience. The classic Control Panel options of older Windows versions no longer exist; the update behavior is configured via sconfig or Group Policy.

Step 1

Open Windows Update Settings

The most direct way to open Windows Update in the Settings app is a command in the "Run" dialog (Win + R).

Open Windows Update

ms-settings:windowsupdate

Step 2

Understanding the Main Options

In the main Windows Update window, you will see the current update status. From here you can:

Check for updates:

Manually scan for new available updates.

Update history:

See a list of previously installed updates (useful for troubleshooting).

Advanced options:

Set active hours during which the server does not restart automatically.

Step 3

Choosing an Update Strategy

Run sconfig in an administrator PowerShell and open the Windows Update settings, or use the Group Policy "Configure Automatic Updates" (gpedit.msc). Choose the method that best fits your maintenance schedule:

Automatic: download and install updates automatically

While secure, this may cause your server to reboot automatically.

Download only: download updates automatically, install manually

A good balance. Updates are ready, you decide when to start the maintenance.

Notify only: notify before download and installation (Group Policy)

Maximum control. Nothing is downloaded until you approve.

Manual: no automatic checks (not recommended)

This is a major security risk and should be avoided.

Summary

Recommended Configuration

For most server environments, "Download only" is the best practice: updates are ready, and you control when the server reboots.

Best practice: Always schedule a regular maintenance window (e.g., during off-peak hours) to install pending updates and perform a controlled reboot.
