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.
