Turn the UAC on using the control panel which you have tried earlier and after trying to enabling the UAC using the Registry Editor and then by Group Policy and hopefully this will remain intact the after restarting.

Registry Editor:

Click Start > All Programs > Accessories> Run and then, type regedit and then hit Enter.

If prompted to enter your credentials by UAC, do so and/or press Yes to continue.

Navigate to the following registry location:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem

In the details pane, locate the EnableLUA key (REG_DWORD type).

On the Edit menu, click Modify. In the Value data box, type 1 (ONE), and then click OK.

Group Editor:

Click Start > All Programs > Accessories > Run and then type secpol.msc and then hit enter.

If prompted to enter your credentials by UAC, do so and/or press Yes to continue.

Find the Local Security Settings console tree, click Local Policies, and then Security Options.

Scroll down and double-click corresponding UAC policy settings to configure.

Close the Local Security Settings window.

There are in total eight Group Policy Object (GPO) settings that can be configured for UAC.

The following list includes the policy settings:

1. Disable Admin Approval Mode.

2. Disable User Account Control from prompting for credentials to install applications.
