Windows Updates Remotely: Download and Install via PSWindowsUpdate PowerShell Module

Operating system is the core of any system, and we have to keep operating system update cause of preventing performance issues, unplanned downtime and fix security vulnerabilities. Windows (client and servers) has a standard terminology for receiving updates monthly and most of organizations using Windows Server Update Services to applying updates of multiple servers/clients. Windows Updates would be downloaded and installed on multiple servers/clients automatically, but service downtime is always the biggest concern, but another concern is installing updates on multiple machines and rebooting systems during planned downtime. PowerShell and WinRM would help us when they come as PSWindowsUpdate module!

What’s Our Story About Windows Updates?

Our story is a drama. I don’t know that why we have workgroup servers yet and why the master of the geniuses can’t understand that we need to Microsoft Active Directory to central managing our Windows servers and users/groups and etc.

They want group of persons to copy updates files on servers and do manual update by run update file and named the group as Operating System Team. I don’t want to explain this silly idea, but I sorted it anyway by some automation.

Now, we have two WSUS servers at each site and those servers designed as up-stream and down-stream to receiving Microsoft’s products updates and deliver to servers and clients. We configured WSUS configurations in each server’s registry and actually there was a registry file for import during server preparation.

We have defined internal process to applying updates on servers with minimal impact on services. At each month, after the Tuesday patch, up-stream servers download the new patches and our colleagues will approve the patches on the related WSUS groups in down-stream servers, server administrators can not apply patches before approval process. After approving the patches, server administrators will install patches by Windows update service in each server, but this process needs many efforts.

Server administrators have to logon to each server and do it manually but there are some automation tools that you can use them in same situations as our situation.
