Microsoft has been clear on this point, even from Vista as an old 
Symantec report notes:

"This message has been echoed by others at Microsoft in response to 
vulnerabilities being discovered in
UAC. Microsoft’s message is that UAC vulnerabilities are not considered 
security issues, as UAC does
not provide a security boundary."

and they

"observed that the User Account Control can be easily disabled 
manually... via the Local Security Policy tool included in Windows 
Vista."
