Windows 11 gets a much needed update that might impact how fast our machines are (in a good way)

If your Windows 11 computer has felt a little sluggish lately, there is some good news. In late May 2026, Microsoft released an important update that quietly improves how fast Windows 11 runs on everyday computers. This is not the kind of update that just patches security holes. This one actually makes things better for people like you who use their computer every day.

The update is called KB5089573, and it went out on May 26, 2026. You probably did not notice it install. That is actually fine. Most of the time, these updates happen in the background while your computer is restarting (This is your reminder to restart your computer.). But the difference it can make is very much worth talking about.

Let me walk you through what changed, why it matters, and what you should do to make sure your computer is getting the benefit of this fix.

🔍 What Is This Update, Exactly?

Every few weeks, Microsoft releases updates for Windows 11. Some fix security problems. Some add new features. And some, like this one, work quietly behind the scenes to make your computer run more smoothly.

The update KB5089573 falls into that last category. It is what Microsoft calls a "preview" update, which means it was released a little early so that technology people could test it before it rolls out to everyone automatically. But it is a real update that real computers can install right now.

⚡ What Actually Got Faster?

Microsoft says this update includes real performance improvements. In plain English, that means your computer should feel a little snappier in everyday use. Things like opening programs, switching between windows, and loading files may feel a little quicker after this update.

This matters especially if you have an older Windows 11 machine. Newer computers tend to stay fast regardless, but computers that are three, four, or five years old often slow down over time as updates pile up. When Microsoft takes the time to actually improve performance, that is a big deal for people who are not ready to buy a new computer yet.

Think of it like a tune-up for your car. Nothing was broken. But after the service, things just work a little better. That is what this update does for your computer.

✅ How to Check If Your Computer Has This Update

Here is a simple way to check whether your Windows 11 computer has already installed this update:

🛠️ What If My Computer Still Feels Slow?

An update like this one can help, but it is not a cure for every slow computer. If your machine is still sluggish after installing it, a few things could be going on:

I have helped many folks in Tyler with exactly these kinds of slowdowns. Most of the time, a one-hour visit takes care of it. I come to you, we go through it together, and by the time I leave, you know exactly what was wrong and how to avoid it next time. There is no judgment, no confusing explanations, just plain talk and real results.

If you want to keep your computer in good shape year-round, I wrote a helpful post called How to Stop Windows Updates from Interrupting Your Day that covers how to set updates to run on your schedule instead of in the middle of something important. I also have a post on how Windows 10 users can keep their computers safe as Microsoft winds down support for that older version.
