Why does the User Access Control (UAC) need to be disabled for Windows Discovery ? SummaryQ. Why does the User Access Control (UAC) need to be disabled for Windows Discovery? The User Access Control (UAC) is a security feature present in the Windows operating system that is designed to prevent unauthorized changes to the system, even if the user account is part of the local Administrator group.However, during the discovery process, if the UAC is enabled on the Windows operating system where the discovery is being run, and the user account is part of the local Administrator group, we will not be able to perform any of the administrator tasks. This is because a prompt will appear to confirm if you wish to use admin privileges to complete the task. Since the discovery is run non-interactively, it will be unable to confirm a UAC prompt. Therefore, we recommend disabling the UAC to complete the job smoothly and retrieve the information we need without any interruptions. For more details related to Windows Discovery, Please click here.
