Description

On Windows, native commands are typically invoked without their extension (e.g.,notepad instead ofnotepad.exe). If a typo is made with this type of command invocation,PSCommandNotFoundSuggestion is unhelpful.

• PSCommandNotFoundSuggestion doesn't check external applications unless you add .exe to the command #10786 from 2019 reported the same issue, in which@SteveL-MSFT commented the following:

  This is already addressed by the fuzzy matching feature for CommandNotFound error

• As of v7.6.0-preview.5,PSCommandNotFoundSuggestion doesn't account for this. No suggestion is generated, as omission of the extension appears to exceed the fuzzy matching distance.

For example:

• ntepadyields no suggestions, despite deviating from the validnotepad command by just a single character.
• Invokingntepad.exe ornotepad.ex is necessary to generate a suggestion.

Steps to reproduce

1. Ensure thePSFeedbackProvider experimental feature is enabled.
2. On Windows, enterntepad into the shell.

Expected behavior

notepad/notepad.exe is suggested.

ntepad: The term 'ntepad' is not recognized as a name of a cmdlet, function, script file, or executable program.Check the spelling of the name, or if a path was included, verify that the path is correct and try again.[General Feedback]  The most similar commands are:    > notepad

Actual behavior

No suggestion is generated.

ntepad: The term 'ntepad' is not recognized as a name of a cmdlet, function, script file, or executable program.Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
