Hi everyone, my rig is DIY, so it started out with no OS. I decided to buy a Dell CoA label of Windows 7 SP1 Professional along with a Dell installation iso file of Windows 7 SP1 Pro from an Amazon seller. Of course, the key on the label and the installation image worked so that I got to this rig to Windows 10 Pro for free. However, I have some concerns about this installation : _Firstly, there are some certain driver tweaks from Dell in the Win 7 iso file. My hard disks are : Crucial MX100 256gb SSD, and a Western Digital Black 1tb. Both use SATA-3 interface, but due to Dell's tweaks, they become 'SCSI disk devices'. The problem persists in Windows 10 ! (Fig. 1) Fig. 1 _Secondly, my rig uses an ASUS Z87 Pro mobo. Despite my system information screen showing the rig is 'made' by Dell (Fig. 2), my rig is still recognised to be manufactured by ASUS by the website windows.com (I log into my rig using a M$FT account) (Fig.3) Fig. 2 Fig.3 Given the 2 concerns above, in case of me changing the disk drives, GPU, or even re-install Windows 10 Pro retail version created by Media Creation Tool from M$FT website, will my rig still be automatically and genuinely activated online after that ? Please help me, thank you very much to anyone helping me out.
