Unable to install windows 7 updates error code 80240016
Click “Start” type “cmd”
Select the “cmd” icon, right click and select “run as administrator”
Accept the dialog that comes up (if it requires entering credentials, do the same) basically we now are running the command prompt in an elevated mode (relevant for Windows Vista & Windows 7)
Type net stop wuauserv
Wait for the WU service to stop and the command prompt to regain focus
Type net start wuauserv
This would start the service again.
After the update you will need to restart the computer!
