OEM Windows keys for legitimate manufacturers.
OEM Windows keys for legitimate manufacturers.
I might have believed the video claimed it was completely free.
OEM key trading on platforms like eBay involves questionable practices. Traditionally, selling volume license keys (VLK) meant sharing identical keys among users, which is why Windows now requires a home key. For systems from brands such as Dell or HP, the BIOS contains a pre-installed key that allows installation of Windows 8, 8.1, or 10 with various configurations. Options include disc keys, flash drives, official installers, or recovery images from Dell systems. While certain keys are tied to specific OEM manufacturers, they generally don’t match exact hardware models. Legitimate system builder keys must accompany proper hardware (like a CPU and motherboard), not just cables or accessories. OEM versions can’t be transferred to new devices, so upgrading requires a fresh key—even if you replace most components except the motherboard and processor. You might also reactivate an old key on a new machine if it was disabled by warranty. Large enterprises often purchase thousands of systems pre-loaded with their own Windows keys, but these are usually paired with enterprise licenses instead. This process can lead to OEM keys appearing on secondary markets like eBay when keys are removed from unused or decommissioned machines. The main concern is that if the key comes from an untrustworthy source, it could be stolen or misused. System builder keys from retailers such as Newegg are more secure since they’re tied to complete hardware setups.
