Windows 10: Default username in UAC prompt

I have three PCs, two running Windows 11 Home and one Windows 11 Pro. On the Pro one and one of the Home ones, when a process requires administrator rights and I am logged in as a standard user, I get the UAC prompt with the username already filled in, while on the third it is blank: can anyone explain this, please, and let me know how to change things so that the username is always filled in. The only difference I have been able to find between the machines is that, on the ones where the username is filled in, an administrator account has the numerically lowest SID apart from the "built in"

UAC Prompt

I am having difficulty accessing a website or PowerPoint document due to an issue with the UAC prompt. When the prompt comes up, I manually enter the username and password.

*** Email address is removed for privacy ***

The UAC prompt goes away for a split second and comes back almost instantaneously. Indicating either the username or password is incorrect. However, the username changes from *** Email address is removed for privacy *** to \*** Email address is removed for privacy ***. I am not sure why it is adding a "\". I am pretty
sure this is the issue. I deleted everything from the Credential Manager and cleared the cache/ history/ stored passwords/ etc. Restarted the web browser too. It is not an issue of wrong credentials either. The username and password have been the same for
a long period of time. The user is not lockedout of their account either.

 

UAC prompts asks for username.

So basically I want the UAC prompt to only ask for my password. Any solutions? I messed around with local security policies but no results.

 

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.
