It's basically runas, but then it pops up the UAC prompt and you have to give admin credentials 😒... runas is much easier, you give the creds in a command line, no windows poping up, nothing, it just works.
That's an odd choice... If it was possible all along to just ask for a a password on the command line, why make it popup a UAC prompt? These are developers using it after all.
Devs can and have used runas in the past, that's nothing new, and it does the job quite well. This new thing is just a fad if you ask me, "every OS on the planet has it and Linux is kinda getting traction, plus we're on team FOSS now and all that, so why not make our own version of sudo, but actually make it more complicated to use than runas 👍" 😒... I mean, they always do shit like this, take some good idea and turn it into crap, but everyone buys into the idea. Why? Cuz they're MS 😒.
