If you want a command line-line solution: download hstart from http://www.ntwind.com/software/hstart.html and extract hstart.exe or hstart64.exe to somewhere on your path, you. You can start an elevated command prompt with hstart /runas cmd
or hstart64 /runas cmd
.
But the fastest way (as noted in a comment for the question) is still to press Windows, type cmd
and press ctrl+shift+enterCtrl + Shift + Enter.
