A sample output with redacted paths, folder names and environment variable values (leaving the generated PowerShell commands, how to get each value):

Notes:

• The available/displayed commands (under 'Special Folder' and 'Environment Variable' headers) will vary from machine to machine.
• The generated values under 'Path' and 'Value' will vary from user to user.
• The redacted 'Path' values are 'FullPath' -type values pointing to a directory. The redacted values under the 'Value' header are mostly paths pointing to a directory, but usually contain also other types of information as well, such as the number of logical processors or the computer name.
