Methodology of Image Deployment

One of the crucial things that have to be taken into consideration as indicated by the director is the fact that there must be a mechanism to preserve user files in the already existing operating system form being lost as Window 7 deployment takes course. Therefore, the project management to be adopted will have take into consideration this fact. To achieve this goal, I as the Network Technician for the company will have to adopt three crucial components of Window 7 deployment, all of which are crucial in saving the already existing user files. These components are application compatibility, upgrade and migration, and desktop deployment.

It should be noted that of the three components of Window 7 deployment, upgrade and migration will play a crucial role in this exercise. Particularly, I will have to ensure that before embarking on a rigorous process of installing new operating systems; I will first of all ensure that all the two hundred and fifty computers actually meets the hardware requirements or conditions for the new operating system. In this way, I will be protecting the possible loss of files duet to system incompatibility and errors. Again, backing data files or having them saved in safe locations has been used extensively by different companies and the results are positive in terms of saving the already existing files, I will also use this process. It should also be recognized that the 250 computers in consideration are grouped into three different work stations but saving the same purpose. However, all these different stations have computers that meets the system requirements hence will not cause any trouble in the process of deployment.    

In order to ensure that the process of deploying Windows 7 is successful, several system tools will have to be gathered and will play different functions. The first tool in the list will be Deployment Imaging Service and Management Tool (DISM) which was fundamentally developed by Microsoft to allow servicing of Windows offline before embarking on deployment. When used in this format, there is a full surety that all files will be saved.  The next tool is Microsoft Deployment Toolkit 2012 (64-Bit) which is the most recent version created by Microsoft and is used as a means of accelerating the work of operating system and Window deployment. In this exercise, MDT will be used at least to automatically distribute and install Window 7 in all the 250 computers from a central location that will be determined in the process.

The next crucial tool is the Windows Deployment Services which offers network installation as opposed to the manual installation that is not only inefficient but also costly taking into consideration the fact that this particular deployment involves a massive 250 computers. Therefore, I will use this tool to aid in the deployment of Window images to the 250 computers without using operating systems. The next tool is Unattended Servicing Command Line whose duty here stems from the fact that the whole process requires installation of multiple packages to the selected Windows 7. Because of this therefore, I will use DISM to apply unattend.xml answer file to the images in order to check both the dependency and sequence of the packages in question. Another important tool to be used will be Image X Tool. Image X Tool is used concurrently with other similar software tools such as Windows Imaging File System Filter (WIM FS Filter), and a Windows image (Wim) file to perform the more complex role of mapping contents of images to a particular directory through actions such as copying and pasting. Lastly, I will solicit the services of Windows Automated Installation Kit to perform duties ranging from installation of unattended Windows, creating of Windows images, as well as capturing of Windows images using the popular ImageX which is readily available on the Microsoft Website.  

Besides the above tools, there are three important other tools that by far are beneficial in this whole process of Window 7 deployment. These are SysPrep, Windows PE and Answer files. The System Preparation (SysPrep) has advantages that can be grouped into three bundles of installation of Windows for duplication, auditing and customer delivery. Windows PE on the other side is used to play the crucial role of pre-installation environment where tools can be tested for effectiveness and efficiency. More so, Windows PE is used continuously as an integral part of other similar setups and recovery technologies.
