Situation: When download and install Windows updates, you may receive this errro: Code 80243004 – Windows Update encountered an unknown error.
Troubleshooting: 1. install the update one by one.
2. Download the updates and install them locally.
3. Modify the Notification: if the Windows Update icon can not popup in the Notification Area, Windows Update won’t start.
- Right click the START BUTTON (or any empty space on the task bar) and select PROPERTIES
- Click the TASKBAR tab
- Click the CUSTOMIZE button for the Notification Area
- At the VERY bottom of the window, click on the ALWAYS SHOW ALL ICONS AND NOTIFICATIONS IN THE TASK BAR
- Try your Windows Updates again. Note that I did not have reboot, log off or even restart services
4. Try to login different user that may fix the problem too.
