HI,
I have a Windows 10 home OS (OEM) which came pre-installed on my laptop. Now im gonna buy Windows 10Pro (retail) pack and activate it on the same laptop. But the vendor informed me that windows 10 Pro will not be successfully activated on my lap top hence it is having a windows 10 home license which isinjected to the BIOS of the mother board and it will automatically convert to windows 10 home again. So i want to know whether it's true or false ?
