Microsoft has released its first proper Patch Tuesday update, KB5040435, aimed at Copilot+ PCs operating on Windows 11 24H2. The update pushes the system to Build 26100.1150 and guarantees numerous enhancements and security repairs intended to enhance user experience and system robustness.

First, this update strongly focuses on security. By fixing many security problems, Microsoft guarantees that your operating system is protected from potential dangers, which increases the safety of your digital surroundings.

Additionally, this is much more than a simple vulnerability update. It includes all the enhancements from the previous update (KB5039304) released towards the end of June. The present update covers the latest fixes and earlier improvements in one package for your system.

One fix that stands out in KB5040435 is the Windows Installer. When you update, if an application is being repaired, then User Account Control (UAC) will ask for your credentials. For people annoyed by the UAC prompt, there is a solution that involves setting a registry value. As you can see below, it may be a simple modification, but it could make a big difference for developers and IT experts who appreciate efficient workflows.

Windows Installer. When it repairs an application, the User Account Control (UAC) does not prompt for your credentials. After you install this update, the UAC will prompt for them. Because of this, you might have to update your automation scripts. Do this by adding the Shield icon. It indicates that the process requires full administrator access. To turn off the UAC prompt, set theHKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer\DisableLUAInRepairregistry value to1.

A second vital correction concerns the Remote Authentication Dial-In User Service (RADIUS) protocol and MD5 collisions. Although these terms might seem complicated, they are essentially about strengthening your system’s authentication procedures to prevent unauthorized entrance.

For gamers on Arm devices, Roblox is not downloadable and playable through the Microsoft Store. However, you can solve this by downloading the game from the Roblox website directly.

Lastly, if you wish to install this update on a machine without internet access, Microsoft has made it available for download from theMicrosoft Catalog. For those machines with an internet connection and using Windows Update to receive updates, your device will automatically get it that way.

The KB5040435 update for Windows 11 24H2 users is not only a regular security patch; it’s the first proper Patch Tuesday update for Copilot+ PCs, and you should download and install it right away. The patch also comes with142 fixes for different CVEs, so it’s even more imperative to update ASAP.
