CommitTransaction is a term commonly associated with database management and transactional systems, where it signifies the final step in a transaction that makes all changes permanent. In the context of the Windows environment, CommitTransaction is not directly applicable as a standalone command or function. However, Windows provides several ways to manage transactions, particularly through its Transactional NTFS (TxF) and Distributed Transaction Coordinator (DTC).

Transactional NTFS allows for file operations to be performed in a transactional manner, ensuring that all operations either complete successfully or none of them do, providing a robust way to handle file system changes. The Distributed Transaction Coordinator helps manage transactions that span multiple resources, such as databases and file systems, ensuring consistency and reliability.

Examples:

1. Using Transactional NTFS with PowerShell: Below is an example of how to use Transactional NTFS in PowerShell to create and commit a transaction.

   # Import the necessary .NET assemblies
   Add-Type -AssemblyName System.Transactions
   
   # Create a new transaction scope
   $transactionScope = New-Object System.Transactions.TransactionScope
   
   try {
      # Start the transaction
   
      # Perform file operations within the transaction
      New-Item -Path "C:\Temp\TransactionalFile.txt" -ItemType File
   
      # Commit the transaction
      $transactionScope.Complete()
   } catch {
      # Handle any errors that occurred during the transaction
      Write-Error "Transaction failed: $_"
   } finally {
      # Dispose of the transaction scope
      $transactionScope.Dispose()
   }

2. Using Distributed Transaction Coordinator (DTC) with SQL Server: Below is an example of how to use DTC in a SQL Server environment to manage transactions across multiple databases.

   BEGIN DISTRIBUTED TRANSACTION;
   
   BEGIN TRY
      -- Perform operations on the first database
      USE Database1;
      INSERT INTO Table1 (Column1) VALUES ('Value1');
   
      -- Perform operations on the second database
      USE Database2;
      INSERT INTO Table2 (Column2) VALUES ('Value2');
   
      -- Commit the distributed transaction
      COMMIT TRANSACTION;
   END TRY
   BEGIN CATCH
      -- Rollback the transaction in case of an error
      ROLLBACK TRANSACTION;
      PRINT 'Transaction failed: ' + ERROR_MESSAGE();
   END CATCH;
