Transactions

A transaction allows a set of changes to be grouped together and committed at the same time. Transactions are only supported under Windows PowerShell.

The registry provider supports transactions, as shown in the following code:

PS> Get-PSProviderName            Capabilities                         Drives ----            ------------                         ------ Registry        ShouldProcess, Transactions          {HKLM, HKCU} Alias           ShouldProcess                        {Alias} Environment     ShouldProcess                        {Env} FileSystem      Filter, ShouldProcess, Credentials   {B, C, D} Function        ShouldProcess                        {Function} Variable        ShouldProcess                        {Variable} 

A transaction may be created as follows:

Start-Transaction $path = 'HKCU:\TestTransaction' New-Item $path -ItemType Key -UseTransaction Set-ItemProperty $path -Name 'Name' -Value 'Transaction' -UseTransaction ...
