Windows updates can sometimes cause problems, such as slowing the system, incompatible drivers, and even blue screens. If you suspect an update is "the culprit", try uninstalling it. Here are a few simple and effective methods.

Uninstall recent updates via Settings

This is the most direct way and is suitable for most ordinary users.

• Open Settings > Apps > Optional Updates (or search directly for "View installed updates".
• Click "Uninstall Update" to enter the "Control Panel" interface.
• Find the update you want to uninstall in the list and click "Uninstall" next to it.

Note: This method can only see the recently installed updates. If you are not sure which one is, you may need to search for it.

Use Control Panel to view all update records

If you want to view historical updates more comprehensively, it is recommended to use the traditional "control panel" method.

• Open the Control Panel (can be via the Start Menu or the Search Bar), and select System and Security > Windows Update .
• Click "View installed updates" on the left.
• Listed here are all the updates that have been installed. You can find the target update by date or KB number and uninstall it.

Tips: If you remember to update the number (such as KB5034276), you can enter the number directly in the search box to quickly locate it.

Uninstall specific updates by command line (suitable for advanced users)

If you already know the update number to uninstall, you can use the command prompt to operate it.

1. Open the command prompt as an administrator (right-click the Start menu and select "Windows Terminal (Administrator)").

2. Enter the following command to view all installed updates:

    wmic qfe list

3. Find the update number (such as KB5034276) you want to uninstall and execute:

    wusa /uninstall /kb:5034276

A confirmation window will pop up in the system, and follow the prompts to complete the uninstallation.

What to do if the uninstall fails?

Sometimes uninstalling updates may fail, common reasons include:

• Updates have been replaced or merged
• Some system files are corrupted
• Missing administrator permissions

You can try this at this time:

• Use the system file check tool to run sfc /scannow to repair system files
• Check if there are any alternative patches for this update on Microsoft's official website
• Or try "reset this computer" as a last resort

Basically these are the methods. Different situations can be used to choose different methods. The key is to first confirm which update you want to uninstall.
