Microsoft released September 2024 patches for Windows 11 KB5043076 KB5043067 and 4 Zero-Day Vulnerabilities. Microsoft has also released the KB5043064 patches for Windows 10, which include improvements and fixes to help the system run better and more securely.
The September update consists of a new feature called Windows Share. Now, you can share content from your Windows PC to your Android device. You need to connect your Android device to your PC to use this. Just use the Link to Windows app on your Android phone and the Phone Link app on your PC.
This update brings a new feature to Narrator that speeds up scan mode. This is particularly useful when using Microsoft Edge or reading large documents. To use scan mode, first turn on Narrator by pressing the Windows logo key + Ctrl + Enter. Then, activate scan mode by pressing Caps Lock + Spacebar while using Narrator.
