Windows 10: Clean install on new PC with non-used windows 7 key

Have an unused Technet windows 7 Key (Old) and want to know if i can use that in some way to install Windows 10 on a self-build PC.

Other option could be to buy an OEM key online, but which online stores are legit?

Installing Windows 10 using Windows 7 key

Thank you, but I still want to know if I can do a clean installation of Windows with my new SSD whilst my old Windows is still installed on the other pc?

 

Installing Windows 10 using Windows 7 key

Once your key is registered with your motherboard you can always exchange the hdd for an ssd, just install it on the new ssd, after successful activation on your old hdd, windows will be activated on the new ssd.

Also a clean install with a windows 7 key will work, just skip the serial and afterwards go to change productkey and fill in the w7 key.

 

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.
