How to save OEM License for future reinstall

[Streiger]

I have my HP Pavilion Notebook - 17-g192nr (Touch) (ENERGY STAR)

and due to bissiness needs I have to install another Operative System.

I will be willing to reinstall the current version in a year or so, and I would like to be sure I´ll be able to do it so.

Do I need to save any info or generate any installation media for the future reinstall?

My current Windows Version is Windows 10 home, but when I purchased the notebook the preinstalled version was 8.1.

It got updated to windows 10 by the usual upgrade process.

Thanks in advance.

There is no need to save any of the license information for Windows 10.  When you go to reinstall Windows 10 just select "I dont have a product key".  Once you get drivers installed and you connect to the internet it should contact microsofts servers and grab your digital license.

Your current install has HP drivers; when you do a reinstall later, that reinstall will NOT have HP drivers.

So, you should follow the instructions in this thread to save off your current drivers so you can reload them after the reinstall down the road:  Backup and Restore Device Drivers in Windows 10 Hardware & Drivers Tutorials 

Good Luck
