Is this true about Window 10

I talked to people at Geek Squad and they said that if you upgraded now and to July 29 your PC will always be able to have Windows 10 even if you replace hard drive since you can use the serial number to show that it's been upgraded form Windows 7 or 8 to Windows 10? Basically your serial number will be like a product key for Windows 10 and you can contact Microsoft and they will send you a CD to install it on your PC? I actually don't know how this works though since I don't think you can use the serial number to put as a CD key when installing Windows 10 fresh copy and activating. But also I don't know if Windows 10 will automatically detect the serial number of the Notebook PC and know it's been upgraded and will activate it without problem. I do know if you have a CD key of like Windows 8 or 7 then that key will be Windows 10 key so you can use that to install a fresh copy of Windows 10 on that machine.

 

Haven't heard of that before, and I wouldn't be surprised if it was actually false since Geek Squad certainly isn't the first thing that comes to mind when I think "knowledgeable tech people".

Here''s an article about the subject:

Basically, your hardware receives an "entitlement" when you upgrade an existing Windows copy to 10. So unless you do a major hardware upgrade, you should be fine; even with a major upgrade, the process to restore the activation is pretty pain-free (had to do it once when I upgraded my Windows 7 desktop''s motherboard).

 

Well the thing is that will Windows 10 know if your PC been upgraded to Windows 10 from Windows 7 or 8 even if you put a new hard drive and install a fresh copy of Windows 10 on same machine?

 

A clean install or a replaced HDD will not affect your W10 license. Windows "will know" that you have done this, but as long as your install gets activated there's hardly any problem, right?

You can upgrade to W10 with a clean install, either by using your key, or by using gatherosstate.exe.

 

It probably pulls some unique hardware identifier out of the BIOS.

 

Microsoft hasn't disclosed how Windows 10 digital entitlements actually work. My understanding is it makes a digital key based on a combination of your hardware but to what extent I don't know. The problem is that entitlements do not yield a key you can use to reinstall it. I haven't checked to see if a key revealer app will dump out the 10 key though like it does for OEM UEFI keys.
