  1. UAC prompt for fsavailux.exe on boot


    I have a PC that is getting a UAC prompt on boot.
    User Account Control
    Blah blahblah
    Microsoft\fsavailux
    Verified Publisher: Microsoft Windows
    I've checked the file on virustotal JIC, and its squeaky clean.

    Anyone have any ideas? Would love some assistance on this one, I'm stumped.

  2. UAC rundll32.exe prompt when opening the settings in the Control panel

    I'm using Win 10 Home x64 with the newest updates. Recently every time I open the mouse, keyboard, sound and few more settings in a control panel I get an annoying UAC prompt that always includes rundll32.exe. I have to confirm every operation connected
    with rundll32.exe. It happens on any Windows account (admin or normal user). For example it looks like this when I try to open the "Playback devices" from the taskbar (it contains this path: "C:\WINDOWS\system32\rundll32.exe" shell32.dll,Control_RunDLL mmsys.cpl,,playback):

    My UAC level is set to default level and I haven't detected any viruses. There's something interesting about the rundll32.exe file in the system32 folder. It has that little UAC icon (so it opens with the UAC prompt) and every other Win 10 PC I have shows
    the normal icon (there is no UAC prompt when I open it). Even after deleting the file and copying it directly from the another PC (retaining its permissions etc. with the xcopy command), it suddenly has this UAC icon. The same file in the backup WinSxS folder
    can be opened without UAC but when it's copied to the system32 folder, it changes immediately. It looks like rundll32.exe file in system32 folder doesn't have the flag "run as admin without the need for UAC elevation prompt" anymore. How can I solve this problem?

  3. Problem with UAC in win 10

    Hi,

    Thank you for posting your query in Microsoft Community. Appreciate your interest in using Windows 10.

    To disable UAC prompts, I suggest you to follow the steps provided below:

    • In the search bar, type Control Panel and press Enter.
    • Click on User Accounts and again click on User Accounts.
    • Click on Change User account control settings.
    • Provide password for the UAC prompt.
    • Drag the box from Always Notify to Never Notify and click on OK.
    • Provide password for the UAC prompt (if asked again).

    Important: Turning off UAC reduces the security of your computer and may expose you to increased risk from malicious software. We do not recommend leaving UAC disabled.

    Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you.
