I’m not sure what is the connection between Windows 10 update issue and non-working start menu/search/task bar on Windows 10, but the below solution worked well for me. Both issues have been fixed by this single command. The error 0x80080008 while downloading Windows 10 update was fixed and able to download and install updates after fixing. Also, the issue of non working start menu in all user profiles, difficulty in shutting down the computer (because power button can’t be accessed from start menu) and the issues in notification area buttons had been fixed by this simple command.
You can try following steps if you have similar symptoms of problems such as 0x80080008 error or non working start menu. We have earlier mentioned few solutions related to Windows 10 network limited connectivity issue here.
0x80080008 Update Stuck Issue on Windows 10
The Windows update may stuck or not work with following error. Restarting the computer will not help.
Other problems such as non working or frozen start menu and buttons, difficulty in shutting down the computer or access the power button and changing the wireless connectivity from notification area also exist with the above update error on my Windows 10 PC.
If you do not have start menu or button problem along with Windows 10 update issue, then you can try the first step first, but if you have the both issues, I suggest you to try the 2nd method straightaway. Because the first method did not work for me, and 2nd worked well and solved both.
1) Try Windows update troubleshooter by Microsoft. You can download the update diagnostic fix from Microsoft site here. Once you run, it should detect and fix the update problem if it can be fixed automatically.
2) Though there are several methods mentioned in other websites to fix this issue, but below method worked for most of the users (including me).
This will restore the Windows 10 base installation health. Your files, programs or nothing will be changed, except some Windows 10 service/package health got reset.
Open the command prompt as administrator (Right Click CMD and select ‘Run as administrator’) and type the following command.
dism.exe /online /cleanup-image /restorehealth
Restart the computer after above command executed successfully.
Now the Windows 10 update issue should disappear and update should run smoothly. Also, the start menu, button and power buttons will start work normally.
Hope this simple guide would be helpful to solve this issue. Let us know if this really help!
