S-
The UAC Visualization driver is left enabled even if you disable UAC and it 'Waits' for the Integrity-Level (IL) check from the kernel, All programs and services also 'wait" for this IL check and only proceed after timing out, Its the down-side to UAC developed programs and having UAC disabled.
UAC has really good security features not found in previous operating systems, refer to this topic for more information
