Clean Install Windows Operating System

Clean Install Windows Vista With Upgrade DVDs.

  Clean Install Windows Vista With Upgrade Traditionally, you are required to have a previous installation of Windows before you can upgrade, e.g. have Windows XP on your system before using Windows Vista Upgrade DVDs. What if you have ALREADY upgraded to Windows Vista but are having system issues that require formatting and re-installing Windows? Paul Thurrot proposed this hack that lets you install a Windows Vista Upgrade, without needing to re-install Windows XP first. This is good for windows troubleshooting and fixing system related problem on Windows OS.

Steps to Clean Install Windows Operating system.

1) Boot from the Windows Upgrade DVD and begin the setup Windows OS program. 

2) When prompted to enter Windows product key, DO NOT enter it. Click "Next" and proceed with setup - this will install Windows as a 30-day trial. 

3) When prompted, select the edition of Windows which you have purchased and continue with the setup. 

4) Once setup has been completed and you have been brought to the desktop for the first time, run the install program from within Windows Vista. 

5) This time, type in MS Windows product key when prompted. 

6) When asked whether to perform an Upgrade or Custom (advanced) install, choose Custom (advanced) to perform a clean install of Windows OS.(Yes! This means that you will have to install Windows for a second time) . 

7) Once setup has completed for the second time, you should be able to activate Windows Vista normally. You can also delete the Windows old directory which contains information from the first Windows Vista installation. 

This means that all Windows upgrade DVDs can be used as full retail DVDs. However, this is an illegal approach and you are going against Windows Vista's EULA, you install an upgrade without owning a previous version of Windows as specified by Microsoft. EULA full form is End User License Agreement.
