At the moment I'm using an old laptop that previously had Windows Vista OEM. I upgraded it to Win7HP using Upgrade Box bought at local retailer.

Now I want to buy myself a new laptop, but the one I chose has Win8 preinstalled. Since I'm going to format the old computer and install linux on it, will I be able to use the Win7 upgrade box license on the new computer as a downgrade option? I don't really like the new Windows and would like to use Win7...

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Because you are dealing with OEM licenses they cannot be transfered between computers. If you want to use Windows 7 that will require a new license. Even if you try the installation will not activate on the new computer. Here is one of many questions on the subject superuser.com/questions/303136/… – Ramhound Nov 25 '13 at 12:38

Finally managed to chat with Microsoft Support. It appears, that I need to install older Windows (Win Vista OEM from old computer should be enough according to the support) and then use the Windows 7 Update Box to upgrade the OS to Win7.


I believe the upgrade license will only work for previous versions of windows and not later versions.

I agree that Windows 7 is far superior to 8 but I am not going to open that can of worms here. If you have a vista disk, install that first then upgrade.

  • why would someone vote this negatively when ITS WHAT I SAID! – Adsy2010 Mar 31 '14 at 16:09
