The Win 7 SP1 product key isn't valid for the standard version of Windows 7.
I encountered a peculiar issue when restarting from SP1 on my laptop, where Windows Update became stuck in the 'checking for updates' state. Despite following all standard troubleshooting steps—reviewing the update logs and similar actions—I didn’t see any of the usual fixes succeed. The SFC scan came back clean. Interestingly, a torrent for the same edition without SP1 bundled (pro x64) was found, but it initially refused my product key until I upgraded to SP1. Once updated, everything functioned properly. This experience made me realize something new; I hadn’t used the vanailla version after SP1 was released. It’s as if they handle Windows 7 SP1 differently, similar to how they treat Windows 8.1—perhaps it wasn’t a service pack?
The key is OEM-licensed for the laptop brand, similar to earlier and newer Windows versions, but unlike retail keys it doesn’t work.
With version 8.1, it supports Windows 8 keys after logging in via the desktop, but not when using the installer.
It seems you're dealing with a retail key. I haven't used an OEM key recently—I mostly rely on home versions. I usually purchase professional keys for advanced features like RDP, and I clear the device afterward.
It has been this way ever since XP was released, but the key should function on newer Windows versions if they have the latest service packs installed.
The decision to exclude 8.1 from the service pack aimed to distance the product from the negative perception of 8. It's purely a marketing strategy.
I realized it functions correctly and that's why I'm astonished it doesn't reverse. At least 7 shows a relaxed approach to activation. And @ Blebekblebek, I verified it myself, though slmgr /dli confirms the retail side.
I picked up a new insight today because you already have the case. You might want to check with Microsoft about activation (especially if you go through the updated ISO path). I usually don’t use the standard installer for every machine I handle; reinstalling from scratch is too time-consuming and slow, plus it causes many restarts.
