Your Windows 11 PC worked fine yesterday. Today, after an update, it’s unstable, slow, or won’t boot at all. Microsoft’s cumulative updates occasionally cause problems—blue screens, black screens, performance issues, or complete boot failures.

Here’s how to uninstall problematic updates and get your system working again.

When Windows Still Works

If your system boots and you can access Settings, removing a bad update is straightforward.

Step-by-Step: Uninstall from Settings

  1. Press Win + I to open Settings
  2. Navigate to Windows Update > Update history
  3. Scroll down and click Uninstall updates
  4. Find the most recent update (usually at the top)
  5. Click it and select Uninstall
  6. Restart when prompted

Identifying the Problematic Update

Look for updates installed around when problems started. Common culprits include:

  • Cumulative Update for Windows 11 - The monthly security updates that sometimes cause issues
  • Feature Update - Major Windows versions (23H2, 24H2) that can bring compatibility problems
  • .NET Framework Updates - Occasionally break specific applications

The update name includes a KB number (like KB5034765). Note this—you’ll need it if the problem recurs.

When Windows Won’t Boot

If your system can’t start normally, you need to access Windows Recovery Environment (WinRE).

Method 1: From the Login Screen

If you can reach the Windows login screen (even if you can’t log in):

  1. Click the Power icon
  2. Hold Shift and click Restart
  3. Keep holding Shift until you see “Please wait”
  4. You’ll enter WinRE

Method 2: Force Recovery Mode

If Windows fails to boot entirely:

  1. Power on your computer
  2. As soon as you see the Windows logo or spinning dots, hold the power button to force shutdown
  3. Repeat this 2-3 times
  4. On the next boot, Windows should automatically enter Recovery Mode

If this doesn’t work, you may need Windows installation media.

Uninstalling Updates from WinRE

Once in Windows Recovery Environment:

  1. Click Troubleshoot
  2. Click Advanced options
  3. Click Uninstall Updates
  4. Choose one of two options:
    • Uninstall latest quality update - For monthly cumulative updates (try this first)
    • Uninstall latest feature update - For major Windows versions
  5. Follow the prompts and restart

Command-Line Method

For more control, use Command Prompt or PowerShell.

Find Installed Updates

This shows all installed updates with KB numbers and installation dates.

Uninstall Specific Update

wusa /uninstall /kb:5034765

Replace 5034765 with your actual KB number.

Offline Uninstall (From Recovery)

If Windows won’t boot, boot from installation media and open Command Prompt:

dism /image:C:\ /remove-package /packagename:Package_for_KB5034765~31bf3856ad364e35~amd64~~10.0.1.0

First, find the exact package name:

dism /image:C:\ /get-packages

Preventing the Update from Reinstalling

Here’s the frustrating part: Windows Update will try to reinstall the problematic update. You have a few options:

Temporarily Pause Updates

  1. Go to Settings > Windows Update
  2. Click Pause for 1 week (or longer via Advanced options)

This buys time while you wait for Microsoft to release a fix.

Hide the Specific Update

Microsoft provides a troubleshooter tool called “Show or hide updates” (wushowhide.diagcab):

  1. Download it from Microsoft’s website
  2. Run the tool
  3. Select “Hide updates”
  4. Check the problematic update
  5. The update won’t install until you unhide it

Monitor for Fixes

Check Windows Update forums and Reddit for reports of your specific issue. Microsoft typically acknowledges widespread problems and releases fixes within days or weeks.

Black Screen After Update

Black screens are often caused by graphics driver conflicts:

  1. Boot into Safe Mode:
    • From WinRE: Troubleshoot > Advanced options > Startup Settings > Restart
    • Press 4 or F4 for Safe Mode
  2. Once in Safe Mode:
    • Roll back the display driver (Device Manager > Display adapters > Properties > Roll Back Driver)
    • Or uninstall the problematic update as described above
  3. Restart normally

When All Else Fails

If uninstalling updates doesn’t fix the problem:

System Restore

If you have restore points:

  • From WinRE: Troubleshoot > Advanced options > System Restore
  • Select a restore point from before the update

Repair System Files

From Command Prompt (in WinRE or Safe Mode):

sfc /scannow
dism /Online /Cleanup-Image /RestoreHealth

Reset Windows (Keep Files)

As a last resort, you can reset Windows while keeping personal files:

  • From WinRE: Troubleshoot > Reset this PC > Keep my files

This reinstalls Windows but preserves your documents and desktop files. You’ll need to reinstall applications.

Important Considerations

Uninstalling updates is often a temporary solution. The problematic update will try to reinstall. Your options are:

  1. Wait for Microsoft to fix the issue and release a corrected update
  2. Identify what specifically conflicts (drivers, software) and update those
  3. Keep the update paused indefinitely (not recommended for security updates)

For security updates specifically, try to find the underlying cause rather than leaving your system unpatched. Check if driver updates, BIOS updates, or application updates resolve the conflict.

The Bottom Line

When a Windows update breaks your system, you have options. Start with the simplest approach—uninstalling from Settings if possible, or using WinRE if not. Block the update temporarily while waiting for a fix.

Most importantly, don’t panic. Windows update problems are common enough that solutions usually emerge quickly. The tech community and Microsoft typically identify and address widespread issues within days of their appearance.
