Introduction
Windows updates are designed to keep computers safe, secure, and running smoothly. They fix bugs, improve features, and protect against cyber threats. But sometimes, updates don’t install as expected. One example is the KB5028980 not applicable on 2012 error. Many system administrators and IT professionals see this issue when they try to install the update on Windows Server 2012 or Windows Server 2012 R2.
This error can be frustrating, especially if you rely on timely security patches. It often leaves people confused about why the update fails or if their system is still protected. In this guide, we’ll break down what KB5028980 is, why it doesn’t apply to some servers, and what you can do about it. We’ll keep everything simple and easy to understand, even if you’re not deeply technical.
By the end of this article, you’ll know exactly why this happens, how to fix it, and what alternatives exist to keep your Windows Server 2012 secure. Let’s dive in.
What Is KB5028980?
KB5028980 is a Windows update released by Microsoft. Its main goal is to address certain security vulnerabilities and performance improvements. Microsoft often releases these updates as part of their Patch Tuesday cycle.
However, not every update applies to every Windows version. Updates are tailored for specific operating systems and service packs. That’s why you may see the error message “KB5028980 not applicable on 2012.” It simply means the update does not match the version or configuration of your system.
Think of it like trying to install a smartphone app that only works on Android, but you’re using an iPhone. The app isn’t broken—it’s just not meant for your device.
Why Does KB5028980 Say “Not Applicable”?
If you’ve seen the error message, you may wonder what’s wrong. In reality, nothing is broken. This message means your server doesn’t meet the requirements for the update. Here are the most common reasons:
- Wrong Operating System Version
KB5028980 may not be designed for Windows Server 2012 or 2012 R2. Instead, it might target newer platforms. - Missing Service Packs or Prerequisites
Some updates require earlier patches or service packs before they can install. If those are missing, you’ll see the “not applicable” error. - Already Installed Through Rollup Updates
Sometimes, the update’s fixes are already included in a larger cumulative update. That means your system already has the changes. - Expired or Unsupported OS
Windows Server 2012 has reached the end of mainstream support, and extended support is also nearing its end. Some updates no longer apply to it.
Understanding Windows Server 2012 Support Lifecycle
When discussing updates, it’s important to understand the support lifecycle. Microsoft provides:
- Mainstream support: Regular updates, security patches, and feature improvements.
- Extended support: Only critical security updates, no new features.
- End of support: No updates at all, leaving systems vulnerable.
For Windows Server 2012, mainstream support ended years ago. Extended support is scheduled to end in October 2023. After that, updates like KB5028980 may not be released for this version. That’s a key reason many people see the error message today.
The Role of Security-Only vs. Monthly Rollup Updates
Microsoft offers two types of updates for older systems:
- Security-only updates: Small patches that address vulnerabilities.
- Monthly rollup updates: Larger packages that include all previous fixes.
Sometimes, KB5028980 is part of a rollup, which means you don’t need to install it separately. If your system already has the rollup, the update appears “not applicable.”
How to Check If KB5028980 Is Installed
Before troubleshooting, it helps to confirm whether your server already has the update. Here’s how:
- Open Control Panel → Programs and Features.
- Click View Installed Updates.
- Search for KB5028980 or check if it’s included in the latest rollup.
If it’s already present, you don’t need to reinstall it. That explains why the installer says “not applicable.”
Fixing the KB5028980 Not Applicable on 2012 Error
If you believe the update should apply but doesn’t, here are steps to troubleshoot:
- Verify Your OS Version
Check if your server is Windows Server 2012, 2012 R2, or another edition. Some updates only apply to certain builds. - Install Required Prerequisites
Make sure you’ve installed previous updates or service packs. KB articles often list dependencies in the “Prerequisites” section. - Run Windows Update Troubleshooter
Built-in tools can detect issues with update installation. - Download the Update Manually
Visit the Microsoft Update Catalog and search for KB5028980. Choose the correct version for your OS. - Check Rollup Updates
If KB5028980 is included in a cumulative update, installing the rollup will cover it. - Consider Upgrading
If none of these steps help, it may be time to upgrade from Windows Server 2012.
Real Example: IT Admins Facing the Error
A system administrator named Alex shared his experience in a tech forum. He tried installing KB5028980 on a Windows Server 2012 R2 machine. The system kept showing “not applicable.” After some research, he realized that the update was already included in the July cumulative rollup.
This shows how important it is to check documentation before wasting hours troubleshooting. Many admins see this message not because of a problem, but because the update is already installed through other means.
Alternatives If KB5028980 Doesn’t Apply
If your server is no longer eligible for updates like KB5028980, here are some alternatives:
- Upgrade to a newer server version like Windows Server 2016, 2019, or 2022.
- Enable Extended Security Updates (ESU) if available. Microsoft sometimes sells ESU for older systems at a cost.
- Use third-party security tools to reduce risks while planning a migration.
- Virtualize your legacy system and limit its exposure to the internet.
Best Practices for Windows Server Updates
To avoid issues like KB5028980 not installing, follow these best practices:
- Keep backups before applying updates.
- Read update documentation to know prerequisites.
- Use Windows Update regularly rather than manual installs.
- Test updates in a staging environment before applying them to production servers.
- Plan for upgrades before end-of-support deadlines.
These steps ensure smoother update management and better server security.
Should You Still Use Windows Server 2012?
If you’re still running Windows Server 2012, it’s time to think about the future. With support ending, relying on such an old system is risky. Cyber threats grow every day, and without security updates, your server is vulnerable.
Yes, upgrading takes time and resources. But the cost of a security breach can be far higher. Planning a migration now will save headaches later.
