ABC1

I have a multi-boot PC with both Windows 7 and Windows 10. As far as I know Kaspersky confuses the 2 different operating systems on the same PC as 2 devices, correct? I have tried that in the past with no success. So, can I buy 2 single-device licenses and use them simultaneously - each one for each operating system ('device' according to Kaspersky) under my single account?
