Windows 11’s new features arriving in April
The company uses the Controlled Feature Rollout (CFR) technology to roll out new improvements gradually, so it may take some time before you see them.
1. Smart App Control behavior changes
Smart App Control (SAC) has now been updated to no longer require an operating system reinstallation to manage it.
The feature is available through the Windows Security app, and it locks the system down, allowing only trusted apps to run in the operating system to prevent unwanted behavior from untrusted apps.
Originally, Smart App Control was available for new installations, and it required completing the installation to turn it off. However, this is changing with the release of the April 2026 Security Update.
If you want to turn this feature on or off, you can do this from Windows Security > App & Browser Control > Smart App Control.
2. Windows Narrator with image description
On Windows 11, the Narrator feature can already generate image descriptions using AI, but the functionality was limited to Copilot+ PCs.
Now, starting with this update, the feature no longer requires a local AI model. Instead, the system will now use Copilot to analyze and provide the image description.
If you want to use this feature, you can use the “Narrator key + Ctrl + D” shortcut to describe the focused image or the “Narrator key + Ctrl + S” shortcut to describe the full screen.
3. Home page in Settings improvements
In the Settings app, the Home page isn’t changing drastically, but you’ll see some refinements in the Device info card to make it easier to understand.
In addition, the company has said that it has updated the Home page to improve the loading performance. You’ll also find reliability improvements when downloading updates from Settings > System > Advanced.
4. About page in Settings tweaks
Now, in the About page, you’ll notice some interesting changes. For starters, the company is reverting some previous improvements, and it now shows again the top cards to show key hardware specifications, such as processor, memory, graphics, and storage.
The change that really got me excited is the addition of graphics and storage details under the “Device info” section. This information should have been available on this page from the start. I’m not sure why it was so hard to include.
5. Accounts section in Settings improvements
In the Accounts section, the company is adding an update that includes an upgrade option for users with a Microsoft 365 Family plan connected to the operating system.
If you don’t want to see this option, you’ll have to turn off suggested content in Settings.
Finally, on the “Other users” page, there’s an updated version of the dialog to change the account time to match the style of the Windows 11 design language.
6. Pen page in Settings changes
I haven’t seen this yet, but the company also mentioned that there are some updates coming to the pen settings page, which now allows you to configure the new “Same as Copilot key” option to open the same app as the “Copilot” key.
7. File Explorer updates
The next cumulative update won’t add any new visual changes to File Explorer, but you’ll notice some fixes and the addition of a new accessibility feature.
For example, after installing this update, File Explorer will now let you use Voice Typing to rename a file.
Microsoft is also fixing a white flash bug when launching a new tab or window when you have the This PC as the default startup page. In addition, this rollout addresses a flash when changing the size of elements in the application.
Finally, this updated version of File Explorer comes with reliability changes to unlock files downloaded from the internet, making it easier to preview them.
8. Display new refresh rate support
The last change, but not the least. In this update, the system will be able to recognize displays reporting 1000Hz or more for refresh rates.
In addition, if you use a native USB4 monitor connection, the controller will now drop to the lowest power state when in sleep mode to conserve battery.
Furthermore, auto-rotation should now work more reliably after waking from sleep. HDR performance has also been improved for displays with non-compliant DisplayID 2.0 blocks. In addition, monitors that rely on DisplayID can now report their physical size more accurately through the WMI monitor APIs.
Final thoughts
The April 2026 Security Update isn’t the kind of release that makes headlines, but it is the kind that quietly shapes how Windows 11 feels to live with every day. These aren’t flashy features, and Microsoft isn’t trying to reinvent the OS here — instead, this update leans into the slow, steady work of making Windows more predictable, more secure, and a little less annoying in the places where it still stumbles.
What stands out is how much of this update focuses on the stuff most people never think about until it breaks: smarter protections, cleaner defaults, and small quality‑of‑life tweaks that smooth out the rough edges. It’s the kind of maintenance release that doesn’t demand attention but earns appreciation over time.
If Microsoft keeps stacking updates like this (incremental, thoughtful, and actually useful), Windows 11 may finally settle into the stable, polished rhythm people have been waiting for since launch. It’s not exciting, but it’s progress, and sometimes that’s exactly what an OS needs.
