I am attempting to disable UAC via a batch file with a REGEDIT command, and everything works - but, I need to be able to do this without clicking. When I run the:

REGEDIT /S somefile.reg

It works fine, except requires and initial click to allow this command. Is there any way around this? I am (temporarily) disabling UAC with the registry edit, but until then it is enabled. Thank you.

Well, first you need to disable UAC, and then you can... – womble Jul 19 '11 at 20:43
@womble - that is what the registry edit is doing, but until the registry edit runs, UAC is on - I am looking for a way around that. – naspinski Jul 19 '11 at 20:56

It rather involves being on the other side of the airtight hatchway... – Evan Anderson Jul 19 '11 at 21:34

Chicken and egg, eh?

Seriously, though, what you're trying to do isn't "supposed" to be possible because UAC (though disclaimed by Microsoft as not being a formal security boundary) is a security boundary of sorts.

In a domain environment you should be controlling User Account Control from Group Policy (the "User Account Control: Run all administrators in Admin Approval Mode" setting under "Security Settings\Local Policies\Security Options" in the computer section of Group Policy is what you're probably looking for).

If you're in a non-domain environment then you'll need to run the script in an already-elevated context. As @womble says in his comment you'll need to bypass UAC in order to disable UAC without invoking UAC. A computer startup script would be one place that you could run this. To install it as a startup script, though, you'll have to be elevated. You're back to the chicken and egg, then.

It looks like UAC is doing exactly what it was designed to... damnit :P – naspinski Jul 20 '11 at 20:28
