Hi guys.
Some time ago I bought a laptop with preinstalled windows 7. I had product key but unfortunately that sticker came off my laptop without me noticing so I didn't take a photo of it. I've recently done free update to Windows 10. I had issues with my hard drive and as I was suspecting it might let go so I found a way how to get my product key, purchased new HDD, replaced it and did clean windows 10 installation. Unfortunately my product key cannot be used to activate windows. I contacted Microsoft support and they advised me that if I can provide them with product key what was on sticker what came with laptop they can activate my windows but obviously that's not going to happen so I'm looking for a cheap and LEGAL way how to activate my Windows. Any help would be appreciated. Thank you…
When you update a legit copy of windows 7 or 8 to windows 10. It ends up with an activated windows 10.
So when you reinstall windows 10 it should be able to install without serial and be activated.
The link below should explain better why this is.
