Microsoft released KB5099414 on July 14, 2026, for Windows 11, version 23H2. This release increments the operating system revision to OS Build 22631.7376. As part of Microsoft's regular Patch Tuesday cadence, this cumulative update delivers routine maintenance, system reliability updates, and critical security patches designed to keep devices secure and stable.
This update specifically targets PCs running Windows 11, version 23H2. It replaces the previous monthly cumulative update, KB5093998 (OS Build 22631.7219), which was released on June 9, 2026. It also builds directly upon the earlier servicing milestones for version 23H2, including KB5087420 (OS Build 22631.7079) from May 12, 2026, and KB5082052 (OS Build 22631.6936) from April 14, 2026.

Should you install it?
Yes, you should install KB5099414 if your device is running Windows 11, version 23H2. Unlike the optional preview releases that appear toward the end of each month, this is a mandatory cumulative security update. It contains essential patches intended to defend your PC against potential security threats and ensure reliable system behavior. Installing it helps prevent software conflicts and ensures your PC remains fully supported on the version 23H2 release branch.
Because this is a mandatory release, Windows Update will eventually download and install it automatically. If you are in the middle of important work or need to ensure uninterrupted system uptime, you can briefly pause updates in your system settings for up to seven days. However, you should plan to allow the installation during your next scheduled restart to keep your device secure.
How to get it
The easiest and safest method to receive KB5099414 is directly through Windows Update. Follow these steps to check for and install the update:
- Open Settings by pressing the Windows logo key + I on your keyboard, or select Start > Settings.
- In the left-hand navigation pane, select Windows Update.
- In the main window, select Check for updates.
- Allow Windows Update to scan for available packages. When KB5099414 appears, it will download and begin installing automatically.
- Once the installation files are applied, select Restart now to reboot your PC and finalize the upgrade to OS Build 22631.7376.
If your computer does not have an active internet connection or if Windows Update encounters difficulty downloading the files, you can install the standalone package manually through the Microsoft Update Catalog:
- Open your web browser and go to the official Microsoft Update Catalog website.
- Enter KB5099414 into the search box at the top right of the page and select Search.
- Locate the download entry that corresponds to your device architecture for Windows 11, version 23H2.
- Click the Download button next to the correct listing, then click the provided link to save the standalone .msu installer file to your computer.
- Double-click the downloaded .msu file to begin the installation wizard. Follow the prompts on the screen, and restart your computer when the setup finishes.
If the update fails to install through standard channels, use built-in system diagnostics before attempting complex changes. First, navigate to Settings > System > Troubleshoot > Other troubleshooters, and select Run next to Windows Update to clear transient download errors. Next, verify that your main drive has adequate free storage space to stage the update files. If installation errors persist, run the built-in system file checker utility to verify and repair underlying system files before restarting the update process.
