We are refurbishing IT material and offering it for free for people in need here in brussels, Belgium.www.linkupasbl.be we have a big stock of desktop computers that we cleaned up and erased with an erasure software.We normally just reinstall windows 10 Pro as they had windows 7 or windows 8 Pro installed before and the numeric license would automatically reactivate windows 10.However we aren't able to do it anymore, all computers now refuse to activate.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Installing Windows 10 using Windows 7 key

Two quick ways to use your Windows 7 key during the install:

1. When asked for the serial #, put in that Windows 7 serial # and continue on. It should activate as soon as it hits an internet connection.

2. When asked for the serial #, at bottom of window click on the I don't have a serial # text (or whatever it says). It will then ask what version you want to install, ie. Home or Pro. Be sure to install the right version that matches your Windows 7 key. Then once you get into windows you can activate by putting in the key. Some people prefer this method, not sure why honestly. Easier to do #1, since the installer will see your key and know which flavor of Windows 10 you are trying to install.

 

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.
