my win10 product key so that i can restore to Win 10 later?

 

Win10 activation key

You don't need a full version, you can use your existing Windows 7 product key to activate.

Click Start > Settings > Update & security
> Activation > Change the product key then enter the new product key then click
Next to Activate

If you are unable to activate Windows 10 after all the above and you are certain you have the correct edition installed, then please attempt phone activation:

Activate Your Windows 10 License via Microsoft Chat Support

Windows 7 came preinstalled on my computer, how do I find the product key?

The product key is usually located on the COA sticker attached to the bottom of your laptop or in the battery compartment. In some rare cases it can also be found in the memory compartment. For tower systems, look at the top or the side of the system unit. It
looks like the following:





If the Certificate of Authenticity (COA) sticker is damaged or letters or not legible, you will have to consider the following options:

• Use a digital camera to capture a picture of the COA then enlarge it on your computer.
  

 

Activation options for Win10 with instant clones

We have a secure (no internet access) lab environment setup to test and validate a VMWare VDI deployment of Win10 clients.

Our issue is activation of the Win10 clients as they require re-activation every time we logoff and back on because we are using instant clones.

Does anyone have any suggestions on the best way to resolve this? Here are the options we are considering and issues as we understand them:

• Setup a KMS server
  • Requires a Volume license, which is doable
  • Documentation says we must have a minimum of 25 hosts, we don' have that in our lab
• Use our MSDN account
  • No support for Win10 KMS license
  • No support for MKS activation
• Manually activate each time
  • Gonna spend a lot of time on the phone
  • Win10 has no grace period so machines are crippled w/o activation

Anyone have a thought or suggestions? I'm hoping I missed something.

Thanks
