[Arman_111]

How can i find my product key, when i have installed windows 10. My pc just starts and turns off automaticly and it repeats.
I can go into bios screen and i also get some opition when i type esc:

(f1 system information)
(f2 system diagnostic)
(f9 boot device option)
(f10 Bios Setup)
(f11 System recovery)

So how can i find it?

Some background info needed:

Is this a preinstalled Win 10, something you bought and installed, or Upgraded from a previous Win 7 or 8.1?

I upgraded this from the previous version from (windows 8.1)

I upgraded this from the previous version from (windows 8.1)

Then no 'product key' is needed.
Upgrading from Win 7 or 8.1 results in a generic license key. The actual verification data is a hash of your old Win 8.1 license and info from your system.

What problems are you experiencing that you'd need the key for?

Hi, i was going to restore to factory reset my laptop. For a while it was stuck at 66% so i took out my battery and plugged it back. Now the laptop start and shuts down after around 5sec autommaticly and it repeats. I don't know what's happending. Can you help me or tell me what the promblem is? Please?

I typer ESC and then f11 (system recovery)
It asked me to (choose an option)
I clicked (troubleshoot)
And then (reset your pc)
And then the only option was (windows 10)

Now it says (insert your windows installation or recovery media to continue)
I need the product key to dowload it.

Can i do something else to get my laptop working again or is it some way to get the product key?

You can download the WIn 10 ISO and create your install media from here:
