    Now that is interesting,
    I was under the impression there was a scheduled Task, that was due to be run to remove the window.old file,
    MIND YOU that was 30 days AFTER the upgrade was installed.

    I did a clean install, not a rollback. Kari was wondering if the keys got blocked after the 30 day period ended. I was just confirming they weren't. As far as I know they are never blocked as a result of doing the free upgrade.

    So there is no chance to get the key once you reinstalled the OS?

    P.S It is indeed a way out to find windows 7 product key.

    The last comment on this thread was more than a year ago. Perhaps you should ask your own question.

    But to answer your question, no. Probably not (depending what you mean by "the key")

    My experience is that a clean install would wipe out any reference to the Product Key on Win7 but Win8 and later may have it embedded in the BIOS, possibly even in Vista [have a Dell that came with Vista that has it that way]. But you might search for and download ShowKey from this forum to check. The Dell I mentioned was first Upgraded to Win7 so I could get the Insider Preview and ShowKey makes no mention of the Win7 Product Key, only the original key that is used by Dell when shipped, not the COA sticker Key.

    True.

    It is October 12 2016 not October 12 2015 though.

    Also true, last post was October 11, 2015 but the 2 posts this AM resurrected it. I'd think posts should actually be closed after a set time to keep issues more relevant, for example, there was the Version 1511 Ugrade and now a year later is Version 1607.

    Microsoft Killing off windows 7 and 8 product keys after Win 10 reg.


    Retired IBM Systems Engineer here. I KNOW this is an old thread but for the benefit of new readers, Registering a Windows 10 upgrade from 7, 8 or 8.1 does not kill the product key for those products, When you purchased them, including when they came preinstalled on a computer of any kind, you are also purchasing a LIFETIME LICENSE to use those operating systems. Just because you put an upgrade on the system does not cancel that users license. Microsoft got hit by the US Courts back in the mid to late 90's over this issue when corporate America upgraded to Windows 95 from 3.11 and ran into problems trying to down grade over the network. Microsoft proclaimed the purchase of the new OS superseded the previous user license but a class action suit brought them to their knees the first time, when the superior court said Wrong, irrelevant of how the original software was delivered, replacing it did not mean they no longer had the lawful right to use it. This also brought about the ruling that software can lawfully be installed on multiple machines, including the OS, as long as only ONE of them is up and running (in use) at a time. This was of MAJOR concern to IBM, as their mini computers and Risc systems load micro code before running the operating system. Micro code is the equivalent of Bios, however it is loaded from the local disk drive not eeprom, allowing for individual machine customization without tying up memory with drivers for custom hardware, or so IBM thinks, in the real world drivers and extra memory are cheaper than customized micro code.

    Yikes! So much wrong information in one post. I think your memory may have faded a bit...

    First, Microcode is not like the bios. Microcode is a hotfix to the CPU itself, altering the way it can execute instructions. For example, this was how Intel fixed the F00F bug and others, and is still used to correct issues in the production silicon. The BIOS is a low-level operating system that provides, as the name says.. Basic Input/output.

    Second, I don't know what you're remembering, but Microsoft has never had their OEM licensing model completely legally challenged. There was an issue in the 90's related to the way that OEM's were charged based on commitment numbers, but it has never been successfully challenged that you can install the OS on more than one machine. In fact, MS's licenses to this day specifically use the phrase "installed on" and not "running on" or anything like that.

    I don't recall any legal challenge about downgrading on the same machine either. In fact, MS has never had any kind of license validation until Windows XP, so it would have been impossible in the 3.x/9x timeframe to make that happen.

    Unless you can cite the specific cases, I just have to call foul on this.
