The Win7 system opens the UAC user Account Control by default, so the UAC dialog box pops up every time the program is installed, reminding you to run the program. However, some users in the Win7 Professional version of the system Installer after the UAC dialog box, found that the UAC dialog "OK" option is grayed out, is not clickable, why is this happening? With this question, the following small series to explain the specific solution.
UAC in Win7 is the "User Account Control" feature, which allows the user to be given advice when the program intends to use administrator privileges. The purpose of this function is to prevent certain ulterior programs from exploiting the authority to "outlaw". In some cases, however, some users find that the UAC dialog box does not click Yes to allow the Trust program to continue running. This occurs because the current account has lower permissions and does not enter the Administrators group. Therefore, to solve this problem, you need to raise the account permissions.

1, the activation of Admin account administrator: As Administrator to run cmd, execute net user administrator/active:yes;
2, cancellation system switch to the Administrator account;
3, in the Administrator account, the administrator mode to perform the following command: net localgroup Administrators your account login/add;
4, log off after the original account, at this time the account has joined the Administrator group, with UAC control authority;
5, after the completion of the modification, it is best to close the administrator account to avoid being illegally exploited by malicious software.
