Update-Help checks the version of the help files on your computer. If you do not have help files for a module or do not have the newest help files for a module, Update-Help downloads the newest help files from the Internet or a file share and installs them on your computer in the correct module folder.
Save-Help cmdlet downloads the newest help files for Windows PowerShell modules and saves them to a directory that you specify. This feature lets you update the help files on computers that do not have access to the Internet, and makes it easier to update the help files on multiple computers.
