Run A Program As Admini But Without The UAC Prompt

[yabab33299]

Hi, how do I run a program as admin but without the prompt popping up and no need for pressing the YES button?

You mean the most suspicious option ever?!

I have no idea what you mean

I suspect BoBo means "What is the point of Windows having built-in security if AutoHotkey can be used easily to circumvent that security?"

The security is there for a purpose. Try working with it rather than attempting to work around it.

There IS a way to do it using a scheduled task but it's not easy and needs elevated rights to create... for a very good reason, otherwise every script kiddie in the world would be blatting Windows installs for fun.

RunAsTask() as been around for 6 years. I use use to run a PowerShell script to update Chocolatey installed apps. I know the risks and I do not need to be reminded every time I run the script!. I don't believe there is an issue here.

Is this safe to use? the RunAsTask()

It's safe to use. It's just a method to automate creation of the required scheduled task. Note that you WILL see a UAC prompt the first time it is used... but not for subsequent uses.

It is just as safe (or as risky!) as pressing YES in the UAC box...

It is so complex, I don't know how to use it. Does anyone have a sample ?

Actually it is pretty easy to use. Run the function at the top of your script. As I said I use it with Chocolatey and this is the script (including the function which can be put in a Lib:

Code: Select all

RunAsTask() 

psScript := "choco upgrade all -y | clip"	
RunWait PowerShell.exe %psScript%,, hide
