A new update for Windows 11 came out in September 2025. For many people, this update works just fine. But for some, it has caused a few small problems. Think of it like a new recipe. For most, the cake turns out great. For a few, it might be a little crumbly. Microsoft knows about these issues and is working to fix them. This guide will walk you through what is happening in simple terms.

The Main Video Problem: A Little “Jitter”
The biggest issue some people have noticed is with videos. If you installed the September 2025 update (known as KB5065426) or the optional one from August 2025 (KB5064081), you might see this.
What does it look like? Some videos might seem to “jitter” or stutter. Imagine watching a movie where the picture freezes for a tiny second, over and over. It can also make videos feel slow or sluggish. It is important to know this does not affect all video apps. Popular services like Netflix and YouTube seem to work perfectly fine.
The problem is mostly with apps that play digital TV or DVDs on your computer. These apps sometimes use a special tool called Enhanced Video Renderer. This tool helps protect movies and shows from being copied, a system called Digital Rights Management, or DRM. DRM is like a special lock on a movie, and the app needs the right key to play it. This update seems to have a problem with that lock-and-key system for certain apps.
You might not even know if your app uses this tool. The easiest way to tell is if your videos are acting strange after the update. If they are, you are likely affected by this bug. Microsoft has said they are creating a fix. The next update for Windows is not far away, so a solution should be available soon.
Other Small Issues to Know About
Besides the video jitters, the update has caused a few other hiccups for a small number of users. These problems are not widespread, but they are worth knowing about.
For Gamers
Some people who love to play games on their PC have run into two different issues.
- Trouble with Certain EA Games: A few games from the company Electronic Arts (EA) have stopped working correctly. This includes popular games like FIFA, F1, Battlefield, and NFL. These games use a special program to prevent cheating, and the update seems to interfere with it. Not many people have reported this, so it may only happen in very specific situations.
- Glitches in Older Games: Some older games that use a technology called DirectX 9 are also having trouble. When the opening movie or cutscene of the game plays, the colors and textures might look wrong or distorted. DirectX 9 is an older standard, so this does not affect new games. Still, if you enjoy playing classic PC games, you might notice this.
For Work and Productivity
The update has also affected some tools people use for work or other projects.
- Microsoft Ink Service: For those who use a stylus or pen with their computer, a service called Microsoft Ink might be broken. This service helps applications understand pen input. One user noted that this update caused an important file (Microsoft.Ink.dll) to stop working in their apps.
- PowerShell Crashes: PowerShell is a powerful tool used by IT professionals and advanced users to manage their computers. After the update, some have found that PowerShell crashes. Microsoft is aware of this. They say it only happens in a very specific “edge case” when using a feature called PowerShell Direct. This means most people who use PowerShell will not have any problems.
- File Sharing Issues: An old method for sharing files between computers on a network, called Server Message Block version 1 (SMBv1), can be blocked by this update. This might stop you from connecting to or sharing files from older devices. Microsoft has been moving people away from SMBv1 for years because it is not very secure, so this may not affect many people.
What Should You Do If You Have These Problems?
If your computer is acting strangely, do not worry. Here are some simple steps you can take.
- Check Your Update: First, see if you have the update that might be causing the issue. You can check your update history to see if KB5065426 is installed.
- Wait for the Fix: Microsoft is already working on solutions for all these problems. The simplest and safest thing to do is wait for the next Windows update. These fixes are usually delivered automatically.
- Back Up Your Files: It is always a good idea to back up your important files and documents. You can save them to an external hard drive or a cloud service. This way, your information is safe no matter what.
- Uninstall the Update (Advanced Step): If the problems are making it hard to use your computer, you can choose to uninstall the update. This can be a bit tricky, so it is only recommended if you feel comfortable doing it. It is often better to wait for the official patch from Microsoft.
These update issues can be a bother, but they are not affecting everyone. For most users, Windows 11 continues to work smoothly. Microsoft is on the case and plans to release fixes for these issues in an upcoming release. Being aware of the situation helps you understand what is going on with your computer and know that a solution is on its way.
