I don't see my older Dell models in Windows ISO Downloader Posted October 20, 2020 1 hour ago, Rebeccah said: And it will be great if the Win 7 product key gets me free Windows 10 -- but I thought from way back when, that it was an either-or deal? You could use the key either on Win 7 or on Win 10, but not both? There's a differnce between what's allowed and what's working. It's working if you use the same key twice on a dual boot setup. It's not allowed though. 2 hours ago, Rebeccah said: Or was that an earlier upgrade deal? It was the initial upgrade deal, but when I last checked a few months ago, it was still working, after all these years. 2 hours ago, Rebeccah said: And with Win 7 no longer supported, does it matter? I'd say no. It's almost impossible these days to buy a Win 7 license that's not pirated, and MS doesn't care. So if you use your key to upgrade to Win 10, and want to buy a new Win 7 key for your dual boot setup, you have basically two options: either spend your money on a new license and support software piracy, or don't spend money on a new license and support your own wallet. Your choice makes no difference for Microsoft. 2 hours ago, Rebeccah said: It's not like I care if Win 7 updates are blocked, since there aren't any, any more. That's true, but getting access to them is a different question... 2 hours ago, Rebeccah said: M4600 service tag is 5691MQ1. Express Service Code is 11261901385. T5500 service tag is 4WLJYQ1.
