In Windows 7 opening Run dialog (Win+R) and confirming with Ctrl + Shift + Enter ran specified command elevated.
In Windows 8 this trick doesn't work anymore and I miss it a lot!
Is there a way to get this feature back?
Do not press Win + R.
Instead, just press Win and type the command directly into the Metro interface. As you type, the search interface will start bringing up possible matches, but just ignore them. When you're done typing, press Ctrl + Shift + Enter, and the command will run elevated, as expected.
This works perfectly for full commands with arguments. It also works for commands without arguments, but with some caveats (matching shortcut, multiple executables, etc.). I have not generally found these to be a major problem.
Okay, I figured it out. It seems to be caused by new a feature of UAC called "Admin Approval Mode" or "AAM". You can disable this feature and (at least with UAC turned off as well) Win+R will run applications as elevated by default. -- I have tried this on 3 machines now and it has worked for me every time.
Here's how to go about disabling it:
If it all worked right, when you hit Win+R at your windows desktop you should see the little shield below the text box that says "This task will be created with administrative privileges."
(Note: I believe you have to have UAC turned off for this to work as well.)
