I purchased a laptop without an operating system and was unsure if it would function. I considered buying a Win 7 OEM key and activating Windows 10, thinking it might be a cost-effective option. Since I did this before with a friend’s build, I wondered if it’s still feasible now.
It's a gigabyte laptop, yet I decided to buy it without Windows (it comes with FreeDOS) since it's much cheaper. If I need to spend around 20€ for a Win10 key, I was hoping to get 7 professional OEM keys for just 3.50€—so I thought it might be worth a shot.
I usually prefer purchasing licenses in W7 formats and performing fresh installations on W10 systems. Upgrades aren’t my favorite approach. It’s usually better to start from scratch. Particularly since yours is brand new, you wouldn’t gain anything by maintaining previous configurations. It’s safer to test a new setup first.
In the end I wasn't able to purchase the Win 7 Pro key for any reason. So I went for a cheaper Win 11 OEM key—maybe it's even a Win 7 key under the hood, since it wasn't that much more expensive. @ewitte mentioned they support Win 11 as well. It functioned perfectly... but I would have really liked to try the Win 7 Pro version.
The 7W sale and support ended a while back. It's unclear if the details are documented, but Microsoft treats licenses as permanent and each new Windows release feels like a free upgrade.
