It doesn't, it has Lenovo's SLIC in the BIOS. More than enough to activate Windows. Device manager would no doubt show it's a mess of not installed drivers though. Big OEMs including Dell and Lenovo use an activation baked into the BIOS and a SLIC (system licence internal code) that's also in the BIOS. No activation required after restore from legitimate or otherwise CD or restore partition. It won't match the code on the machine's sticker, even if it's 100% legit just bought new from maker. Search will turn up plenty on how SLIC works.
