Yes there was a Win 10 Enterprise Trial loaded first on that backup PC HD.
That backup PC's power supply just died tonight. It has been sitting since 2015, guess the capacitors, etc. died.
I ordered a new power supply. Should be here in about 2 days.
I will post again when I get the new PS, clone a SSD, and try the Win 7 Product Key.
I'm sorry that I didn't reply sooner but had a bad medical issue.
I replaced the PS, cloned a new SSD to my primary computer's system drive.
The back up PC booted with no problems, no message of any hardware changes as far as Windows 10 is concerned!
MS Office 2019 Pro Plus did detect the hardware change and said I needed to reactivate it. I'm not doing that now, only if needed if I use the backup PC at some point if my primary PC dies.
The question I have now is since the backup PC seems to run the cloned Windows system and files with ease from the primary PC without changed hardware detection will that change down the road and I will still need to add the Win7 Ultimate Keycode to get it going again? Can this backup PC just stop 30 days from now, sort of like in trial mode?
The old 30 day period died out years ago. There is no time limit for running it unactivated but it does contravene the EULA to do this.
Basically, your backup is fine. I recommend you fire it up periodically and keep it updated. The one thing that sometimes breaks an installation is not updating for a long time, and pc struggles to update.
As I stated in my first post that I just want to know that the backup computer will accept the primary computer's SSD and run the same as the primary SSD even if I need to purchase a new license. I don't plan on using the backup computer at all until the day that my primary computer dies for some old age reason. If the primary computer's motherboard or CPU dies then the SSD swap to the backup computer should all that needs to be done and try to reactivate Win10 online, or purchase another Win10 copy and use the new key. The primary computer's Win10 was a free upgrade from Win8, which was an upgrade from Win7 thus no Win 10 key.
When Windows 10 or 11 is activated for the first time on a computer, there is a digital license for that edition of Windows (Home or Pro) for that unique computer stored on Microsoft's activation servers. When the same edition of Windows 10 or 11 (Home or Pro) is reinstalled on that computer, either via clean install or SSD transfer or image restore, if the hardware has changed Windows will send the unique ID for that computer to Microsoft, and if the digital license is found there matching the Windows edition, it is returned and Windows 10 or 11 will reactivate itself.
Office does not have that feature, so that is why it complained about activation and Windows did not.
Windows 10 and 11 licenses and product keys are exactly the same.
