+Passing ``--refresh`` will update all registrations for installed runtimes. This
+will recreate Start menu shortcuts, registry keys, and global aliases (such as
+``python3.14.exe`` or for any installed scripts). These are automatically
+refreshed on installation of any runtime, but may need to be manually refreshed
+after installing packages.

 In addition to the above options, the ``--target`` option will extract the
 runtime to the specified directory instead of doing a normal install.
 This is useful for embedding runtimes into larger applications.
