Upgrade or update of cubase 7 towards Cubase 10 - Windows 7 or 10 ?

Hello,
Thank you for your quick reply !
OK for the information.
I just have another question:
I just bought this Cubase 10 update.
I am still on Windows 7.
Can I wait a few months to upgrade to Windows 10 and install this update and get a warranty if it does not work, and if so, how long does this warranty last from the date of purchase?
