This can indeed be a devastating and annoying experience. If you are suffering from this problem, read on to find a solution to deal with Windows Server 2019 not booting after update.

Quickest Way to Fix Windows Server 2019 Won’t Boot After Update

Unfortunately, the only way to fix these issues is to uninstall the corresponding cumulative update for your Windows 2019 version. You need to follow the steps below.

1. To resolve this issue, restart your Windows Server 2019 in Safe Mode, which will allow you to log in and remove the problematic update from Windows Update. You can usually enter safe mode by pressing F8 immediately after the Server starts.

2. Type command prompt in the search bar and run it as administrator.

3. To remove the update from the command line, run the appropriate command for your Windows Server 2019 operating system:

• Windows Server 2019: wusa /uninstall /kb:KB5009557

✨ Note: for Windows Server 2012 R2 or Windows Server 2022, run the following commands.
✦ Windows Server 2012 R2: wusa /uninstall /kb:KB5009624
✦ Windows Server 2022: wusa /uninstall /kb:KB5009555

✔ Additional points: If the Server is configured to download and install updates automatically, it will reinstall the wrong updates. To prevent this, you can hide updates to prevent reinstallation.

• Uninstall the update and then run Check for updates from Windows Update in the Server.
• Right-click the update and select Hide Update to prevent it from being reinstalled.
