Ok probably some tweaks that i apply on windows change that... But i found a strange solution ... here in regedit
HKEY_CURRENT_USER - software - microsoft - windows - CurrentVersion - polices - explorer - and just double click on NoWindowsUpdate and set value data to 0.
and it work but i really want to know how to enable that in "normal way" from my admin account for all other users . Maybe it is a noob question but im really not in that managing account stuff...
