Whenever I want elevated rights (via the Windows 7 User Access Control dialog), I need to input the [LaptopLocalName]\administrator. Because the user is in the domain, you cannot even just type administrator without a domain prefix.
Windows 7 does not seem to cache the suggested entries. Together with the password this amounts to a lot of typing.
Any chance to put a list of "favorite admin users" into the registry or policies?
The actual answer (or at least an equivalent workaround) can be found here: How can I get the UAC/elevation prompt to remember my local username?.
I only have an indirect answer.
I don't know of any way to monkey with the UAC, but I do know of a way of caching text in an an easily accessible manner.
For these purpose I use a clipboard replacement utility that has the ability to remember not only past clipboard data, but also permanent list(s) in which one can stock text strings that are easily accessible via a hotkey.
Gizmo's article Best Free Clipboard Replacement Utility recommends quite a few such utilities.
