How to know windows version was installed on my HP laptop by the manufacture?

[irisha3103]

My case: I have bought the laptop with Windows10 (licensed product) on board and then by fault downloaded Windows 8(not licensed)

And now I would like to turn back to Windows 10

I heard that if you bought the laptop with licensed windows, so in future you can get your windows back by your laptop number... Something like this.

Question is: Is it true? If yes, how to do it?

Thanks in advance

Also I dublicated this question on StackExchange here 

https://superuser.com/questions/1352232/is-there-a-way-to-turn-back-to-windows-10

As far as I understood I need to figure out from HP support what is the Windows version exactly was installed by manufacture on my laptop and than I have to ask Microsoft support to provide me a link to this ISO Windows version and than I need to download it and my laptop automaticaly will pull licence key to activate the Windows.

Is it right? So, how to know exact version of Windows that was installed by default on my laptop?

Hi,

Your PC originally came with Windows 10 Home 64-bit

You can see here:

You can download Windows 10 or create a USB drive with OS on it, by downloading media creation tool and running. It will give you option to create USB drive or download iso. When you install on your PC you do not need product key as it is embedded in firmware and Windows 10 will automatically activate once installed and connected to internet:

First you need to create the pendrive with Windows 10 on it.

So, insert the pendrive in the PC,  turn off PC by holding power button. Press power button and immediately keep pressing ESC  until startup menu appears and then press F9 and choose the pendrive in boot menu. Once it boots from pendrive follow the procedure to install Windows. Choose custom install and delete all partitions on hard drive and then use the unallocated space to perform the install.  You do not need a product key as it is in the firmware. Windows will automatically activate once installed and connected to internet.

When finished installing allow Windows to completely update and find all or most drivers. You can follow this process by going into settings > Security and update > click on Verify for updates. You might need to reboot a couple of times. Once completely updated you  can go into device manager and see if there are any missing drivers (there will be yellow exclamation mark next to the device). You can find these drivers and software on HP support page for your product.

Here is also a good guide. Start from "How to Get Installation Media and Do a Clean Install of Windows 10"
