+Lack of granular execution access control
+-----------------------------------------
+
+Windows does not have a similar concept to `sudo`_/`doas`_/`please`_
+(`sudo`, but with regex). Users cannot run arbitrary commands as a given
+user without knowledge of the alternate user's password (see
+`runas`).
+
+This creates difficulty for large multi-user systems when assigning
+roles without administrator access. Performing tasks that need to step
+outside of low privilege is not a simple matter without divulging the
+alternative user's credentials.
+
+Unix systems support the SUID execute bit (normally mode 4755) on a
+binary which, when executed switches process ownership to the file
+owner, not the user that executed it. This is sorely lacking in
+Windows and would change the access landscape if it were implemented,
+many organisations could then solve many issues where users execute
+programs as a privileged user when they wouldn't otherwise need to.
