Not sure about dual boot win 10 & win 7

[Sam21]

Hi guys can someone please give me some advice

I understand that after upgrading to windows 10 i have a month to return to windows 7 if i want to, then i think windows 10 takes the serial number of my windows 7 and then that serial number will no longer activate windows 7.

If that's correct and i dual boot windows 7 & 10 and windows 10 has used the windows 7 serial number will the windows 7 not activate

Your interpretation is incorrect.

Yes, after installing Win 10 over your Win 7, you have 30 days grace period if you want to go back to Win 7.

No, you never lose your Win 7 product key. It's yours to keep.
You can always use your Win 7 product key together with your Win 7 installation DVD to reinstall Win 7 any time you want.

If you install Win 10 over your Win 7, your Win 7 product key is tied to the install.
You cannot install Win 7 to anywhere else using the same Win 7 product key.

You cannot install Win 7 to anywhere else using the same Win 7 product key.

So if my windows 7 product key is tied to the install of windows 10

you say i cannot install using the same win 7 product key so if i want to dual boot i will have to buy a new win 7 product key

There is no "reliable " source to buy a genuine Windows 7 software with genuine product key.
The danger is ....... you don't know if you have the real McCoy or a counterfeit.

I would keep the current Win 7 you have and go and buy a Windows 10 from retails stores, or from Microsoft.

Newegg still sells OEM versions of Windows 7.

Hi i have a spare OEM version of windows 7 that's not been used. but if i use that one i dont think dual booting is worth the bother unless i have a lot of apps that will not run in win 10
