Windows 10: New win10 system build, how do I activate from my old upgraded win7?

Hi,
I'm building a new system and would like to use the license from my dismantled old system.
The old system started with win7 and has been upgraded all the way up to win10 through the years.
I purchased a "Windows 10 Home 64-bit Installation/Recovery Disc Only" to simplify things.
I will install this first.
From what I read I now have a digital license for the old system.
I'm wondering how do I transfer the license to the new system?
Do I need to "un-register" the old system?
I have the original product key but my new system has completely new hardware (except for DVD player) so I don't see how the license can be linked automatically.
I haven't tried yet so I'm just gathering info for when I do in a couple days.

Thanks!

:)

 

Win10 on new hard drive, how to activate

• Installed Win10 to new hard drive, but Win7 code does not work.
• Tried online (slui.exe 4) activation:
  • entered numeric codes online - which failed,
  • talked to 1st line tech who entered Win7 code - did not work,
  • transferred me to 2nd line tech and no one came on the phone line after 2.5 hours.

Win7 was pre-installed on HP computer with no media provided and HP support has no process to supply replacement media or ISO (last HP purchase). Tried to install Win7 to new drive using Recovery Disks I created, but it could not find system image.

Not willing to return to old hard drive as the new one has SSD and is at least 3 (7?) times faster.

QUESTION 1: Is my only option now to buy either Win7 or Win10?

QUESTION 2: Without activation, when will Win10 no longer boot? If 12 months, I can retry online activation later.

Win7 to Win10 upgrade issue ... 0xC1900101-0x30017 and then 0x40017

hi, Andre,

yes, i think my note did say that i already created the bootable ISO on a DVD and started the Win10 upgrade from there. i already contacted the vendor and he gave me a list of Win10 drivers, suggested the bootable ISO upgrade method but did not recommend
a new BIOS update.

My PC is a ZOTAC CI320none with an Intel processor running a licensed Win7 Home Premium SP1.
