It looks that way. If there is no watermark, your not running 10525 or 10532. The way its supposed to work on a clean install is, if you did the free upgrade and activated, a clean install on that same PC will activate. I think Microsoft goofed with 10240. When that build released there was no watermark and no detectable expiry date, even if you originally clean installed the Insider preview and hadn't opted out. Opting out then, got you a free Windows 10. For some anyway. Clean installs after that activated for some but not for others. Consider yourself lucky. Well I guess who ever gets that PC is the lucky one.
