Would using KMS auto activator invalidate my windows 10 license?

[Guest]

Hi, I recently received a gaming laptop (g752VL) with preinstalled windows 10 and installed important softwares and upgraded to build 10586. I installed btw a pirated copy of office 2016 and I think I might have accidentally pressed activate windows first before office using KMS auto activator. I just recently realized when I got a watermark at the bottom right of my screen after restaring my laptop telling me to activate my windows. I foolishly opened once again KMS auto and pressed activate windows again in the hopes of being able to revert it back to original. And so it did (I think) my question is would that invalidate my pre-installed legitimate windows license and regard it as fake/invalid? I thought of doing a system restore but kinda got scared that I might mess up everything or the fear of it freezing during the restore session, which would mean I have to deal with recovery (which I have no experience in doing yet) the KMS auto activator I used did not require any installation.
Please let me know what actions should I take.
(Yes I pirated office since I don't make money yet to buy a legit office license, and the laptop was a gift for my 3d projects in school so please don't tell me I can buy a gaming laptop but I can't buy an office license)

Sorry if your messing about with that activator has hosed up your PC.
However, Toms Hardware does not assist with fixing, supporting, recommending pirated software of any kind.

About the only thing I'll suggest is either a Restore point to before you did this, or a full factory reset.

Oh, and LibreOffice.
