Reset Windows 10, Key or not?

[spree]

Hello, my mum got some kind of virus on her laptop, and she asked me to reset it. I won't need a key, or? Nothing has changed inside of her computer, but it is the free upgrade windows 10 running on her PC. 

 

I will be using the recovery method from windows own settings (not booting from flash drive etc) so do I just click "skip product key" or whatever? (If the answer above was I dont need a new key)

-Thanks

You don't need a key, it won't ask for one when you reset it.

Alright mate, thanks.

In fact, even if you format completely it should reactivate with no problem as now Microsoft saves your system "as the key". I must say both this and the reset function have proven to be really useful for me. Damn it, I feel like a console peasant, and I like it!

 

JK, in any case I usually log in with my Microsoft account so even if I change a major component like the motherboard, Windows is still valid as long as I log in with my Microsoft account.

the key is locked to the motherboard with windows 10 so you wont need the key again. just press activate later if it asks you
