"Q: What happens if I change the hardware configuration of my Windows 10 device?
A: If the hardware configuration of your Windows 10 device changes significantly (e.g. motherboard change) Windows may require re-activation on the device. This is the same experience as prior versions of Windows (e.g. Windows 7 and Windows 8.1). The free upgrade offer will not apply to activation of Windows 10 in such scenarios where hardware changes reset Activation."
I wondering if this will become a issue as i rebuild/replace parts in my pc often. (Most the time now that i have to order parts online)
I have been known to gut my desktop for parts to repair other (friends pcs and such as I order the parts and they needs theirs up asap ( i have a laptop for when pc down) So I wondering if there will be a issue when I do this some time . I will actually install windows on a junker that not got the parts they need to get by. I will end up with multi different hardware configs as i go though different repairs. I know at time that it will look like i am running 2 computers if the windows 10 key is only set to hardware configs. I know other gamers' change stuff monthly. I also find that these prebuilt systems (dell and such) don't offer media disk to do restores. I don't always have access to quality internet speed to download a restore image for every model when they had a harddrive failure./ or a upgrade to a larger drive .
