Assembly: System.Management.Automation (in System.Management.Automation.dll)
|High||The action performed has a high risk of losing data, such as reformatting a hard disk.|
|Low||The action performed has a low risk of losing data.|
|Medium||The action performed has a medium risk of losing data.|
|None||Do not confirm any actions (suppress all requests for confirmation).|
This enumeration is used when setting the ConfirmImpact parameter of the Cmdlet attribute and the $ConfirmPreference shell variable. Remember that it is up to the developer to determine if their cmdlet or provider has a high, medium, or low risk of losing data.
Users can set the $ConfirmPreference shell variable so that only cmdlets and providers with an equal or higher impact level can request confirmation before they perform their operation. For example, if $ConfirmPreference is set to Medium, cmdlets and providers with a medium or high impact level can request confirmation. Requests from cmdlets and providers with a low impact level are suppressed.
For more information about impact level, see Requesting Confirmation.
