Dozens of Windows users reported encountering the error message 0x800736b3 when installing the KB5044284 pack. The error prevented them from installing the patch on their devices.

Fortunately, error message 0x800736b3 is quite common in the world of Windows updates, and there are many ways to fix it, as you can see in our extensive article about it. Yes, it happened in Windows 10, but Windows 11 is no different, so the same solutions will work here, as well.

Alongside the regular solutions, such as running the SFC can, or resetting the Windows Update components, however, it might be worth trying a simple trick before attempting to install the KB5044284 pack again.

• Unplug all external peripherals except the mouse, keyboard, and LAN cable to start the installation process.
• Disable or even uninstall any third-party antivirus software that you might have installed on your PC. These might interfere with the update installation process.

These two solutions seem to have worked for many Windows users who couldn’t install the KB5044284 pack because of the 0x800736b3 error.
