+title: Sudo for Windows
+homepage: https://stackoverflow.com/a/40321310/151312
+tagline: |
+  Sudo for Windows gives you a minimal `sudo` that works in cmd.exe and PowerShell.
+---
+
+## Cheat Sheet
+
+> Sudo for Windows isn't real `sudo`, but it's close enough for certain tasks -
+> like installing WSL (the Windows Subsystem for Linux), without opening a GUI
+> to Alt-Click "Run as Administrator".
+
+### Example: Enabling WSL
+
+```bash
+sudo.cmd dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
+```
+
+### Raw PowerShell
+
+`sudo.cmd` is simply an alias of a powershell elevation command:
+
+```pwsh
+@echo off
+powershell -Command "Start-Process cmd -Verb RunAs -ArgumentList '/c cd /d %CD% && %*'"
+@echo on
+```
+
+Note: replace `/c` with `/k` if you'd like the window to stay open rather than
+closing automatically.
