What are Windows Updates

Let’s talk about some basics. When we install an operating system, software, or image a machine, we always ensure it is patched with latest updates. Not only operating system but also every software that we use needs to be constantly updated.
Windows updates are released to fix security issues, fix bugs, issues in operating system, and to add new features to OS. The Windows Updates are relying on Windows Update service which is set to start automatically by default.
Windows Update service will downloads & installs recommended and important updates automatically. Microsoft updates can be classified into following categories:-

Critical Updates
Security Updates
Definition Updates
Drivers
Update Rollups
Service Packs
Tools
Feature Packs

Introduction to Windows Server Update Services

WSUS enables the administrators to install the latest Microsoft product updates. WSUS is a Microsoft Windows Server role and when we install it, you can efficiently manage & deploy the updates.
One of the highly important tasks of system administrators is to keep client pc and servers updated with the latest security updates and Windows software patches. Without WSUS it could be really hard to manage the Windows updates.
When you have a single WSUS server in our environment, the Windows updates are downloaded directly from Microsoft Update. Rather than downloading updates directly from internet letting to multiple computers. We can setup WSUS server and allow the clients to download all the updates from a WSUS server. With WSUS we can save Internet bandwidth and also speed up the Windows update process.

In the first place let me cover about WSUS lab setup. I consider that the best way to master WSUS is to deploy and configure it in the test or lab setup first. Then we can start working on it and try several things.
I have created 3 virtual machines in my lab.

Server Name	Operating System	Role Installed
DC2019.test.local	Windows Server 2019 Standard	Active Directory, DNS, DHCP
WSUS.test.local	Windows Server 2019 Standard	WSUS
Windows10.test.local	Windows 10 Professional	Windows 10

When we have decided to implement WSUS in our setup, First we must first look into WSUS requirements. Please visit Microsoft. It will cover all the information required for WSUS requirements.

WSUS Firewall Ports / Exceptions

It is important that the WSUS server connects to Microsoft Update to download updates. If there a corporate firewall between Internet and WSUS server, we might have to configure that firewall to ensure WSUS can acquire updates.
To gain updates from Microsoft, the WSUS usage port 443 for HTTPS protocol. You should allow Internet access from WSUS to the following list of URLs.
