RunasCs is an open-source C# utility for running processes with explicit credentials on Windows, serving as an improved alternative to the built-in runas.exe. It supports multiple CreateProcess functions, various logon types, UAC bypass, and stdin/stdout/stderr redirection to remote hosts.

Use cases

• run a process as another user with explicit credentials from a command line
• spawn processes from service contexts where runas.exe fails
• bypass UAC when an administrator password is known
• redirect process input and output to a remote host
• execute commands with NetworkCleartext logon type to avoid UAC limitations
• automatically select the best process creation function based on current token privileges

When to choose

• you need to run processes under different user accounts with explicit credentials on Windows
• the built-in runas.exe fails due to service contexts, DACL issues, or UAC restrictions
• you are performing penetration testing or red team operations requiring flexible process execution
• you need stdin/stdout/stderr redirection to a remote host

When to avoid

• you need a cross-platform credential execution tool (Windows only)
• you require a GUI-based tool for switching users
• your use case is unrelated to Windows process creation with alternate credentials
