On Windows 11, Microsoft has confirmed that the January 2026 Security Update (KB5074109, build 26200.7623) is triggering additional issues that can prevent some devices from booting properly.
Although the company has already released two out-of-band updates to address earlier problems, Microsoft now acknowledges that this particular failure remains unresolved, and neither emergency patch (KB5077744 and KB5078127) corrects the boot issue.
How to uninstall the buggy January 2026 update from WinRE on Windows 11
If you must uninstall a quality update from the recovery environment, you can complete this task in at least two ways.
Option 1
To uninstall the latest buggy update using Automatic Repair to enter WinRE, use these steps:
- Power on the PC.
- After the Power-On Self-Test (POST), and you see the blue Windows logo (if applicable), press the power button again to shut down.
- Repeat steps 1 and 2 multiple times to trigger the Windows Recovery Environment (WinRE).
- Select your account (if applicable).
- Confirm the account password.
- Click the Continue button.
- Click the Advanced Startup button to continue.
- Click on Troubleshoot.
- Click on Advanced options.
- Click on Uninstall Updates.
- Click the “Uninstall latest quality update” option.
- Sign in using your administrator credentials (if applicable).
- Click the “Uninstall quality update” button.
If you cannot access the Windows Recovery Environment this way, then proceed with the steps below.
Option 2
Before you can proceed with these instructions, you will need to ensure your new computer can boot from the USB flash drive by checking the Unified Extensible Firmware Interface (UEFI) settings.
Since every computer is different, you’ll need to check your device manufacturer’s website for more specific steps.
Alternatively, nowadays devices may also offer a boot menu option that lets you choose which device to start the computer from. If your system supports this option, you can use it to launch Windows 11 Setup without changing the firmware. (One more time, the only way to know this is by checking your manufacturer’s website for more specific steps.)
To uninstall the latest buggy update using a bootable media to enter WinRE, use these steps:
- Connect the Windows 11 USB flash drive to the device.
- Start the PC.
- Press any key to continue.
- Choose the installation language and format.
- Click the Next button.
- Choose the keyboard and input method.
- Click the Next button.
- Select the “Repair my PC” option.
- Click the Next button.
- Choose the keyboard language.
- Click on Troubleshoot.
- Click on Uninstall Updates.
- Click the “Uninstall latest quality update” option.
- Choose the target operating system. For example, “Windows 11.”
- Sign in using your administrator credentials (if applicable).
- Click the “Uninstall quality update” button.
Once you complete the steps, the device will uninstall the most recent update, allowing you boot directly into the desktop.
If you also want to prevent the same update from installing again, immediately after uninstalling it, open Settings > Windows Update, and click the option to pause updates. You can also use these steps to disable Windows Update entirely.
