From time to time I encounter a problem that, according to Google, no one has ever had before. When I find a solution, I'll post it here. Making the internet better one "I can't be the only person to ever have this problem" post at a time. Expect Windows, Android, and Linux.
Windows 10 allows quick access to user- and admin- level command prompts in any folder without adding any shell extensions. Open File Explorer, select any folder, and go to the File tab on the ribbon. Options will appear for Open command prompt and Open Windows PowerShell. Hover over either and you'll see options for opening either as administrator. Thanks, Microsoft!
