Some browser updates arrive with long release notes, detailed changelogs, and a clear explanation of what has changed. But then there are updates like this one — quiet, unannounced, and without any official documentation to guide us. These silent releases often spark curiosity because they hint at behind-the-scenes work happening at Microsoft, even if the company is not yet ready to talk about it publicly.
This new Microsoft Edge point release, version 143.0.3650.75, rolled out on December 9th, and although it doesn’t bring visible feature changes, it still plays an important role in the browser’s stability. Let’s walk through what this update is, how to verify it, and why it matters even without an official changelog.
Checking Whether Your Browser Has the Latest Update
Before we try to understand what this update might include, it helps to begin with the basics — confirming whether your PC has already received it. And instead of simply listing steps, let’s walk through the process naturally.
When Edge updates quietly in the background, many users never notice it until something breaks or something improves. So it’s always good to manually check your current build number, especially when Microsoft releases a point update without explanation.
How to Confirm Your Version
- Open Microsoft Edge.
- Click the three-dot menu (•••) in the top-right corner.
- Select Help and feedback.
- Choose About Microsoft Edge.
Edge will now check for updates automatically and display your current version. After this silent point release, you should see:
Version 143.0.3650.75
The previous build was 143.0.3650.66, so the jump to .75 confirms that Microsoft pushed out a new patch even though the official changelog has not yet been updated.

Why This Update Feels Different
This section deserves a moment of reflection. Unlike Chrome, which updates first and publishes security notes almost immediately, Edge usually receives its fixes a little later. This timing pattern is one reason why today’s update stands out — it arrived too early to be a Chrome-based security patch.
That leads us to two likely explanations, both of which help us understand Microsoft’s intentions here.
Possibility 1: A Standard Bug Fix and Performance Patch
If we look at Edge’s history, Microsoft frequently rolls out small performance updates between the major security cycles. These patches might not introduce new features, but they stabilize existing ones, improve memory handling, enhance tab performance, or fix regressions that users have reported after a version upgrade.
Since version 143 was released only a few days earlier (on December 4th), it’s very likely that:
- Some users encountered minor performance issues
- Small bugs appeared in niche features
- Microsoft detected telemetry reports indicating instability
In these cases, a quick point release like 143.0.3650.75 is exactly what Microsoft usually pushes.
Possibility 2: A Silent Security Mitigation
Although less likely, there is always the possibility that Microsoft has patched a security issue quietly — without publishing details. This typically happens when:
- The vulnerability is not yet widely exploited
- Microsoft wants time to investigate further
- Disclosure may aid malicious actors before devices update
But based on the timing and the pattern of release cycles, this particular update behaves more like a stability patch rather than a zero-day fix.
The script you provided also reflects the same belief — that this is probably not a security update we need to worry about, simply because Edge normally follows Chrome’s cycle, and it’s too soon for the weekly Chromium security bundle.
No Visible Feature Changes Yet
After installing the update, I explored the browser just as you did — looking through the Settings panel, the sidebar, the toolbar, and all user-facing elements. Everything remained unchanged.
This reinforces the idea that this update is internal, focusing on smoothing out the version 143 experience rather than introducing anything new.
These invisible improvements might include:
- Faster tab switching
- Reduced crashes
- Better handling of PDFs
- Memory optimizations
- Stability improvements for WebView
- Fixes for newly added 143-series features
While these changes don’t always get documented immediately, they often solve frustrating little issues users encounter after a major version upgrade.
Why You Should Still Install the Update
Even without a changelog, this update is still important. Browser patches — especially point releases — keep your system stable and prevent future problems.
If you have noticed:
- Slow performance
- Tabs freezing
- Random UI glitches
- Extension interactions misbehaving
- Increased CPU usage
…then updating to 143.0.3650.75 may quietly resolve those issues in the background.
And even if you haven’t noticed anything unusual, it’s still worth installing. Browsers evolve constantly, and these small patches often prepare the groundwork for upcoming features and future security updates.
Final Thoughts
This update might feel invisible on the surface, but it is another reminder that browsers today are living software — changing, improving, and adapting even when the developers do not announce every adjustment. Whether it’s a bug fix, a quiet performance enhancement, or a preparatory patch for something larger, keeping Edge fully updated is always the safest path.
Once Microsoft publishes the official release notes, any additional details will become clearer. But for now, the most important action is simple:
check your version and install the update if it hasn’t arrived automatically.
