Windows User Account Control (UAC) is a feature of Windows operating systems that was introduced with Windows Vista. It limits the ability of standard users to make global system changes to a workstation and prevents malicious software from making unauthorized changes to protected areas.
Note:
For details on UAC, refer to your Microsoft support information or see http://technet.microsoft.com/en-us/library/cc709691(WS.10).aspx.
Disconnected Scanning is unaffected by Windows UAC. If UAC is enabled, Disconnected Scanning functions normally, without any UAC interaction (for example, no UAC pop-up windows are displayed, and you do not have to re-enter your Application Server address when logging back on).
