Hi all,
I have the following trouble when I use Quick Assist tool of Windows 10:
all users inside company are "Standard User" and they can not run any software as Administrator.

Sometimes these users ask me remote support, so we use Quick Assist App.

My issue is that very often I need to insert Administrator account to execute operation,
but I can not see screen that permit me to type administrator account and password.

How can I solve it?
I must avoid this problem otherwhise I can not support users remotelly!

It is fine for me that I can see UAC prompt and I can type admin user and password to assist employees.

All PC has got Windows 10 2004 or Windows 10 20H2 inside company.

Thanks so much
Federico

    Hi Federico,
    As far as I understand it, at the moment if you use Quick Assist , when you connect to a remote users laptop/PC and try to do anything that requires an administrator elevation, the screen is just blanked out.
    In the GPO editor, go to Security Settings > Local Policies > Security Options > User Account Control: Switch to the secure desktop when prompting for elevation to Disabled
    Hope this helps and please help to accept as Answer if the response is useful.
    Best Regards,
    Carl

    Hi @Reza-Ameri ,
    Laptop has got lastest Windows 10 updates.

    Quick Assist app works fine.

    My issue is that:

    1. Remote user is a standard domain user (no administrator privileges)
    2. When UAC message appears I can't see anything about it and I can't type administrator password.

    I hope to be clear
    Federico

    Dear @Carl Fan
    Thanks!
    You are right! I created a domain policy (with your settings) and I applied it to Clients OU.

    Is It a vulnerability?

    Thanks

    Was this solved by GPO? I have the same problem, but I am in Intune.

    I enabled this setting in Intune using the Settings Catalog, I ensured the policy has been applied, but still UAC is blacked out...

    I also saw then in mmc local sec policies, that the setting is applied...
