I recently found Win Toolkit, And found a tutorial on Youtube on Integrating updates into windows 7, That wen't pretty smooth! So i proceeded to integrate updates into windows 8.1 64bit but now i'm running into a error when mounting the extracted folder i get this messaged (ESD format is not supported. Please do not rename the extension to.wim as it still will not work. WinToolkit 2.x will support ESD files) TIA
