Windows 10: Clean install using USB, cannot verify key as no network

If Windows 10 was activated before you did the clean-install, you can click Skip when you are asked for the key. Just make sure you select the correct version Home or Pro, if you are asked and then continue. Windows 10 should activate again when online.

 

What product key did you try to enter?

 

You shouldn't need a product key. Just click skip. If you try to upgrade and you get this message, then you are probably using the wrong Windows 10 version.

 

Hi, you might try the workaround described HERE (other thread).
In my case nothing would happen beyond a certain point; a "manual" upgrade of older drivers (SATA & PCI-bridge) helped.
Good luck!

 

Why would not not need a product key on a clean install ? I read now somewhere else that MS are doing away with product keys for OEM and going with hardware signature, but how are you supposed to know this during your fresh install if they dont tell you ? They ask for key, you enter key, they say key is invalid.
Why is MS being deliberately a pain in the butt over all this ?
Distinct lack of information from MS during upgrade and fresh install.

I ended the matter by purchasing a FULL VERSION of Windows 10 and using the key on a fresh install. I did this because i will need to replace the motherboard/CPU/Memory on this computer in a few months anyway.

Thanks to all those who tried to help, and apologies if i came across angry or aggressive in any way, but this is a joke from MS, but it seems people are just willing to run with it.

 

Germany's best informed computer journal "c't" described in its VERY basic how-to-dos that you have to do a first install from within a running Win-7/8 so the "old" product key will be registered ONCE on a win-10 server.
After that one you may do as many clean installs as you like ...

Product keys are attached to the motherboard-ID is one more thing they found out: You can replace memory, hard disks etc. but only get in trouble after swapping the motherboard.

 

"Product keys are attached to the motherboard-ID" This is for OEM only though right ? Full version you can still switch hardware ?

 

It depends upon which type of activation you have which depends upon the method by which you achieved activation.

Two examples:

1. You do an in place upgrade from Windows 7/8/8.1 to Windows 10. The Windows 10 will create it's own activation based upon the genuineticket.xml file created during the upgrade (the license for the previous OS, not the product key) and use the generic product key that everyone gets for an upgrade. It will push that activation along with the hardware ID to Microsoft activation servers for future use. That is called a digital entitlement. If you have such a digital entitlement stored on MS activation servers then no product key is required in the future because Windows 10 will retrieve the license from Microsoft using the hardware ID. (In layman's terms, "tied to the motherboard"). This type of activation cannot be moved from computer to computer (or motherboard to motherboard) because there is no unique product key to generate a new activation with.

2. You purchase a Windows 10 Product Key for a new computer that has never had Windows 7/8/8.1 on it. You activate Windows 10 by entering your purchased Product Key. This type of activation is just like the old activations - it retrieves a license from Microsoft activation servers based upon the unique product key entered. This is called a Product Key activation and is not stored on Microsoft activation servers (although they do track the number of times and frequency that product key is used). Each time Windows 10 is re-installed, the product key will have to be entered for activation.

 

Sorry for the delay.
Yes, if you buy a Windows-10 license that will NOT be attached to a motherboard.

If you previously bought a separate win-7/8 license, you might even "move" a free win-10-upgrade (internet, or saved on USB stick / DVD) to a new PC/motherboard but would first have to install your win-7/8 before doing the upgrade to win-10.

Btw: It was mentioned in the article that MS promised free win-10 updates for one year - leaving it open what will happen thereafter.

 

After the year they will probably remove the offer and force anyone to buy Windows 10 if he hasn't yet upgraded. I cannot blame them, we are given the chance for one year. If we miss it, it is our fault, not theirs.

So if you upgrade from a previous version or use the utility to create the GenuineTicket.xml file then your activation data are stored in Microsoft's server and you can clean-install Windows 10 on the same hardware without using a key (click skip). This means using the same version (Home or Pro) based on the previous Windows version. In that case you can change most of the hardware (better not all at the same time) but changing the motherboard would make automatic activation impossible. Then you would have to call Microsoft, explain that you upgraded your system, and they might be kind enough and activate you again.

If you buy a retail Windows 10 version, you have to enter the key when asked. A retail version can auto-activate 2-3 times (as long as there aren't many changes to the original hardware) and then you have to do it by phone. If they see on their records that it is your 5th or greater attempt to activate the same key, they will be suspicious that you may give it to friends and start asking you questions like in how many computers you have installed it etc. You will have to convince them that you are legitimate and they might activate it one last time. Next time forget it! With a retail key you can do as many changes as in the first case (anything but motherboard) with the difference that it will activate 1-2 times online and you won't have to call Microsoft for a small change. If you overdo it with upgrades to the hardware, you may be forced to buy a new license! So don't! A regular user will upgrade his computer once or twice and then buy a new one. It is certainly not common to upgrade it once every few months and it will draw suspicion.
