This article explains if you can upgrade Windows 7 to Windows 10
The only Elo products that can be upgraded from Windows 7 to Windows 10 are those that were sold by Elo with a Windows 10 sticker already on the back. If there is no Windows 10 sticker on the back, then it would be necessary to purchase a copy of Windows 10 from Microsoft and install it.
On Windows 10 devices, the Windows product key is embedded in products (in the hardware) and is not available to provide to anyone for any purpose; it is inaccessible, per our license agreement. Our OEM license agreement allows us to sell the operating system only when installed in our products, therefore, we do not just sell Windows licenses.
Here are the steps to upgrade products that have the Windows 10 sticker on the back:
1. Follow the steps for “System Recovery” as outlined in the product’s User Guide.
b. Touchcomputer/POS products: https://www.elotouch.com/touchscreen-computers.html
c. IDS computer modules/ECM’s: https://www.elotouch.com/catalog/product/view/id/1243/category/19/
2. When given the choice of which Operating System to recover, choose Windows 10.
3. The computer will then install Windows 10.
