A transaction allows a set of changes to be grouped together and committed at the same time. Transactions are only supported under Windows PowerShell. This section briefly explores this feature with no expectation that it will return in more recent editions of PowerShell.

Registry        ShouldProcess, Transactions          {HKLM, HKCU}

FileSystem      Filter, ShouldProcess, Credentials   {B, C, D}
Function        ShouldProcess                        {Function}
Variable        ShouldProcess                        {Variable}
