In a hypothetical situation, where I have two hard drives on the same system. Hard drive A has windows 7 ultimate dual booting with windows 8.1 MCE retail. Hard drive B also has my windows 7 home OEM dual booting with another windows 8.1 MCE retail ( different key from A). I want to upgrade all 4 OSes to windows 10. I believe this should be possible, right. Since microsoft allows for changing hard disk or GPU, what is really differentiating these systems ? Is it the serial numbers ? How about those with the old Technet/MSDN keys that allowed for multiple activations? If the activations of windows 7 happen to be on the same system.
I don't think Daz loader will be sufficient to qualify people for free Windows 10 upgrade since part of Windows 7 OEM licensing the device should carry a valid COA hence I expect MS will request the user to enter the COA at a certain point to garnt him the free W10 upgrade
There will never ever be a COA requirement, you can't f**king read the COA on many W7 laptops anymore..................................................................................................................... seriously.
Plus if a Windows 7 PC passes OEM validation then it can be upgraded to Windows 10 by design. Microsoft could of only allowed retail keys, but they want every Windows 7 owner to update because they don't want older versions of Windows to become the new Windows XP. That's why I'm certain that Microsoft will never ask for a COA key to upgrade you to Windows 10.
Yeah, that's why I said "plus" Many Windows 7 laptops that have actually been used on peoples laps would have faded stickers by now. I mentioned this exact issue to FaiKee a month or two ago.
So that means if I change my system or build a new PC I'd need to format, reinstall windows 7, activate it again and then re-upgrade back to windows 10?
Both confirmed. Just upgraded my HTPC, upgraded with one HDD, clean installed on another. Only problem was ATI GFX card kept causing a BSoD on the clean install, swapped for an old GeForce, activation happened as soon as I connected to the net.
1. configure basic settings. 2. install basic drivers, updates. 3. make backup image of freshly installed OS. 4. install programs and all else.
So I literally can't buy a new PC or change specs after the first year is over because i'd then need to actually buy windows 10? Well that's... I guess the upgrade system only works for laptops (as long as you use the same laptop forever)
if you were to buy a new PC after a year from now, it would have Win10 on it for you already (most likely lol)
You can change the specs, but not the motherboard. Also to avoid deactivation I'd make 1 change per reboot just in case changing your GPU, CPU and HDD all at once is too much. If you were to buy a key then that's obviously not going to be tied to your hardware.
