Why Need WSUS Services?

Microsoft developed Windows server update services to provide a better running service in the computers connected to a network. Compared to its predecessor software update services, the WSUS server checks the required updates faster for all systems connected to a network.

WSUS successfully reads the requirements of the system and the version of the updates that are best suitable to run on the system. Then downloads all the much need software updates.

In a corporate field, where more than one computer is connected to the server or host computer. Keeping up with the updates rather becomes more essential than ever. If the system doesn’t have the latest update, then it might miss out on new growing information available on the internet.

One of the reasons why Windows software update services are so popular among its users is it supports a wide range of Microsoft products. The functions of this software balance out between the normal Microsoft operating system and more advanced versions of the system seen in bigger organizations.

While the Windows server update services carry a lot of functions on its back but some of the important fiction it provides the users are

Manually doing everything on a computer can be a tiresome thing on a daily basis. Updating is the task that will have to perform every single day.

These updates not only add a brand new number to your current version but will also make the current function even stronger.

Wusu server provides automatic software updates for every Microsoft product. You don’t have to download the entire software catalog all at once. You will choose the ones you need the most and the less used ones.

If you have a group of systems, one of them didn’t download the updates, but all the others did. With the WSUS server, you don’t have to download the entire software package all over again.

With WSUS, you would have the function to choose the system that needs the latest version, target the download, and the system makes WSUS a better option for updating.

WSUS makes sure you receive better reports in a Knick of time. So you can be up-to-date with the events that are happening around the world. Compared to SUS, WSUS provides a much better quality of service that will make your workload run in proper order.

Language Support

The reason why you see so many people around the world using the WSUS server for this system is. It is because of the sheer language it supports in its system. Language may not be a concerning factor for some companies or individuals.

But for others, this can be one of the most important things that they expect software to have. WSUS server provides services that mean a lot to people from different walks of life.

System Requirements

To enable Windows software update services, your configuration has to meet the minimum standard to continue the service.

  • Processor: 1.4 gigahertz (GHz) x64 processor ( anything above 2 GHz will make it a lot faster)
  • Memory: WSUS requires two gigs of RAM to function the system without any shuttering. Adding more will certainly be good, but the effect on the performance may not be noticeable.
  • Available disk space: 10 GB, but you should have over 40 gigs for an advanced installation
  • Network adapter: you don’t have to get a top-shelf product for minimal activity. Make sure your network adapter supports 100 Mb per/sec.

Software Requirements:

Some software you will need is Microsoft Report Viewer Redistributable 2008 to view reports of WSUS service. You can view any kind of report if you have an older version of the Windows server.

But if you have a Windows server 2016, you will need to upgrade the report viewer redistributable to 2012. Otherwise, having an older version might not support newer devices.

WSUS Firewall Ports And Rules

Before making WSUS firewall ports and rules for this server, ensure all updates are connected to the right server. In this case, it would be the Microsoft server. The connection must be set to the Microsoft server to receive updates.

Suppose there is a firewall between the Windows server and the Windows server. That firewall might interfere with the update system of WSUS. So, if you have another firewall, then configure that firewall for the smooth running of the WSUS server.

To start receiving updates, you need to connect to the WSUS firewall port 443 to follow the HTTP protocol. After this stage, you must allow a connection to the following list of URLs.

  • http://*
  • https://*
