Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.

Windows 10 product key not working after clean install

Do not enter any key. Look for the tiny "Skip", "Skip this step", or "Do this later" options when asked for a key and click on those.

 

Which product key is needed for clean install of windows

By way of explanation:

When Windows 8 came out on 26 October 2012, there was a £/$15.00 offer that upgraded any recently (~6 mo) purchased Windows 7 OEM edition to 8.0 Pro Retail. Quite a good deal at the time. And a free upgrade to MCE Pro followed, both obtained by contacting Microsoft, who used 3rd party partners to handle sales, and email product keys to applicants.

Both the 8 Pro and the 8 MCE Pro product keys given out with these offers are valid upgrade keys for Windows 10 Pro.
