Windows 11 Tips: How to Check KB Installed and Boost Performance

Are you curious about the specific Windows 11 updates you’ve installed, particularly the KB (Knowledge Base) updates? These updates are crucial for maintaining your system’s security, performance, and stability. But how do you go about checking which ones are already on your computer? This blog post will guide you through various methods to uncover the installed KBs on your Windows 11 machine.

1. The Windows Update History – A Quick Glance

The most straightforward way to see a list of recently installed updates, including KBs, is through the Windows Update history.

1. Open Settings: Press the Windows key ++ I or search for “Settings” in the taskbar.
2. Navigate to Windows Update: Click on “Update & Security” and then select “Windows Update” from the left-hand menu.
3. View Update History: Click on “View update history.”

This will display a list of recent updates, including KB numbers, dates installed, and the update type. However, this method only shows recent updates, and you might need a more comprehensive solution for older KBs.

2. The Power of the Command Prompt – Uncovering Hidden Details

The Command Prompt is a powerful tool that can provide detailed information about your system, including installed KBs. Here’s how to use it:

1. Open Command Prompt: Search for “cmd” in the taskbar and run it as administrator.
2. Execute the Command: Type the following command and press Enter: `wmic qfe get hotfixid, installedon`

This command will list all installed KBs with their respective installation dates. This method provides a more comprehensive view than the Windows Update history but might require some interpretation for beginners.

3. The Registry – A Deep Dive into System Details

The Windows Registry is a central database that stores various system settings and configurations, including information about installed KBs.

1. Open Registry Editor: Search for “regedit” in the taskbar and run it as administrator.
2. Navigate to the Key: Go to the following path: `HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionComponent Based ServicingPackages`
3. Inspect the Values: Within this key, you’ll find folders named with KB numbers. Each folder contains various information about the corresponding update, including its installation date and details.

While this method provides the most detailed information, it’s crucial to exercise caution when navigating the Registry, as incorrect modifications can lead to system instability.

4. Dedicated Tools – A Simplified Approach

Several dedicated tools can help you easily identify installed KBs without navigating through complex system settings.

1. Windows Update History Viewer: This free tool provides a comprehensive view of all installed updates, including KBs, with additional details like the update description and download size.
2. Show Updates: This tool allows you to view installed updates and filter them by KB number, date, and other criteria. It also provides a convenient option to export the list for future reference.
3. Microsoft Update Catalog: While not specifically designed for checking installed KBs, the Microsoft Update Catalog offers a comprehensive database of all available updates, including KBs. You can search for a specific KB number to see its details and download it if needed.

These tools simplify the process of checking installed KBs, making it more accessible for users of all levels.

5. The Importance of Keeping Track of KBs

Understanding the KBs installed on your system is crucial for various reasons:

• Troubleshooting: If you encounter any issues with your Windows 11 system, knowing which KBs are installed can help you identify potential causes and find solutions.

6. Staying Informed – Tips for Effective KB Management

Here are some tips for effectively managing KBs on your Windows 11 system:

• Enable Automatic Updates: Set your Windows Update settings to automatically download and install updates, including KBs. This ensures your system remains up-to-date with the latest security patches and performance improvements.
• Check for Updates Regularly: Even with automatic updates enabled, it’s a good practice to manually check for updates regularly to ensure you’re not missing any critical KBs.
• Review Update History: Make it a habit to review your Windows Update history to see what KBs have been installed recently. This can help you identify potential issues related to specific updates.
