Windows photos question

Alright heres the deal. My laptop has been unused for 2years. Originally bought in 2013 by a buddy. After 2years of no activity i scrubbed the hard drive, encrypted it, installed a copy of windows 10 i found online, used a mac address changer, used a completely different wifi that i dont own, and encrypted my system. I go to open a photo someone sent and the windows photos shows photos i had back in 2006!!!!! Wtf!! How in the hell did it ever grab my photos without me being aware of it and how in the hell after all that trouble did it miraculously know im me and put all my photos from 2006 in my computer? I mean im not upset because i lost all my photos and its nice to be able to reclaim old photos of me when i was ten years younger but how in the hell could it figure it who i was, from photos back in 2006 that i didnt even know it stored, on a laptop that was bought in 2013 wity all the changes i mentioned? Someone must know...

Oh and forgot to mention i was using an anonymous proxy. So how in the hell did windows know who it was? Could they have at one time recorded an internal serial number and at one point connected that with me from 2006?

I never even heard about one drive until recently. Was it even around in 2006 to gather my photos? Maybe it was. Thank god they werent inappropriate sexual photos lol

It is probably your IP address
