Microsoft Quietly Retires RSS Feeds for Knowledge Base Monitoring

Microsoft has quietly pulled the plug on RSS feeds that many Windows users and IT professionals relied on to track new and changed Knowledge Base (KB) articles. The change arrived with little or no announcement, removing a long-standing way to monitor Microsoft’s support content the moment it updates.

According to AskWoody, who first flagged the disappearance, the feeds that let people watch for KB changes are no longer available. The timing lines up with a wider industry shift: Reddit is also retiring its RSS feeds, and in both cases the suspected culprit is AI content scraping.

Here’s what changed, why it matters, and what you can do about it.

What exactly changed

RSS (Really Simple Syndication) is an old but still widely used format that lets you subscribe to a website’s updates through a feed reader. Instead of repeatedly visiting Microsoft’s support site, you could point a reader at a feed URL and get notified whenever a new or updated KB article appeared.

Microsoft maintained these feeds for years, and they served as a lifeline for IT administrators, security researchers, bloggers, and power users who needed to stay current on support documentation, troubleshooting guides, and security advisories. Now those specific feeds have been taken down.

The removal appears deliberate rather than accidental. Microsoft did not issue a prominent announcement, which is typical of how it handles infrastructure changes to its support portals.

Why the timing matters: AI scraping

The most plausible explanation, according to reporting from AskWoody, is concern over AI scraping. Large language models and other AI systems routinely crawl public web content to train their models, and RSS feeds are an easy, structured way to pull large volumes of text in one go.

By removing the feeds, Microsoft may be trying to make it harder for AI scrapers to mass-download its support content. Reddit has made a similar move, citing the same AI scraping concern as its stated reason for retiring RSS.

This is speculation about Microsoft’s exact motivation—the company has not publicly confirmed the reasoning. But the parallel with Reddit suggests an industry-wide pattern rather than an isolated decision.

Reddit’s parallel move

Reddit’s decision to retire RSS feeds has drawn significant attention, and for good reason. Reddit was one of the last major platforms to keep RSS widely available, and its users had fought hard to preserve it over the years.

Like Microsoft, Reddit has pointed to AI scraping as a factor. The platform’s content is highly valuable to AI training, and RSS feeds provided a convenient way to harvest it at scale.

The two moves, taken together, signal that even content-heavy companies that once leaned on open feeds are closing them off. The era of freely syndicated web content is shrinking.

The broader decline of RSS

RSS is not new. It dates back to the early 2000s and peaked during the blog era. Over the past decade, adoption has steadily declined as social media, email newsletters, and in-app notifications took over as the primary way people consume updates.

Still, RSS retained a loyal user base among technical audiences who value a decentralized, ad-free, and algorithm-free way to follow content. The loss of Microsoft’s KB feeds is a notable blow to that community, since it removes one of the last enterprise-grade sources that power users depended on.

What this means for you

If you relied on RSS to track Microsoft KB updates, your workflow will change. You’ll need to either visit the support site directly or find an alternative way to monitor changes.

For most casual users, the impact is minimal—you probably already check the support site or rely on notifications. But for IT admins, security researchers, and content creators who built automated workflows around these feeds, this removes a convenient piece of infrastructure that was easy to take for granted.

What you can do

A few options remain to keep track of Microsoft’s support content:

Check the Microsoft Support site directly for new and updated articles.
Use Microsoft’s official RSS feeds where they still exist, though the KB-monitoring feeds appear to be gone.
Look into third-party feed aggregators or services that may still surface the content.

The broader takeaway is that open, machine-readable content feeds are becoming rarer. If you depend on RSS, it’s worth backing up your feed URLs and diversifying how you track the sources you care about before more of them disappear.
