+// This file is an NSIS plugin which exports a function that starts a process
+// from a provided path by using the shell automation API to have explorer.exe
+// invoke ShellExecute. This roundabout method of starting a process is useful
+// because it means the new process will use the integrity level and security
+// token of the shell, so it allows starting an unelevated process from inside
+// an elevated one. The method is based on
+// https://blogs.msdn.microsoft.com/oldnewthing/20131118-00/?p=2643
+// but the code has been rewritten to remove the need for ATL or the C runtime.
+
+// Normally an NSIS installer would use the UAC plugin, which itself uses both
+// an unelevated and an elevated process, and the elevated process can invoke
+// functions in the unelevated one, so this plugin wouldn't be needed.
+// But uninstallers are often directly run elevated because that's just how
+// the Windows UI launches them, so there is no unelevated process. This
+// plugin allows starting a needed unelevated process in that situation.
