(Side-by-Side Trace Utility) is a legitimate Microsoft command-line tool designed to debug Side-by-Side (WinSxS) errors. Windows uses the WinSxS folder to store multiple versions of DLLs (Dynamic Link Libraries) and assemblies (like Visual C++ runtimes). When an application requests a specific version of an assembly that is missing or corrupted, Windows generates a side-by-side error.
