Change Account Type button is not enabled even as administrator user
i have windows 7 x64 in my dell precision notebook.
i have administrator user and tommy user.
tommy user is in admin group. but not able to execute any program but its account type is standard.
then i logged in as administrator and went to UAC there i try to change the account type of tommy user from standard to administrator.....as soon as i click the administrator's radio button. the "change account type" is disabling...its not enabling.
how can i solve this problem?
