    If it's true there will be a disclaimer that you have to accept before it continues with the installation. No way they will attempt to pull a gotcha.

    He is completely full of horse pucky as any one with a computer shipped with an OEM version of windows tied to bios would still be able to revert. They wound not take the small percent that bought an OEM version with key that tied it to the hardware and screw them like that.

    It will not be a one way street if you have your old install key and media or if you have recovery media to clean install your old OS again. (I would pull a copy of your "cd" key before your upgrade). So some my ask who are you how do you know this information? Well I am not a Microsoft employee but I have installed hundreds of computers and every time having a valid key (with slmgr or phone activation) and your correct install media did the trick for Windows 7 and 8.x in those cases. As for downgrading no you will probably (like I am 99.99% sure) have to do a clean install of your old OS but it should still be possible.

    Your best option is to make a backup of your OS before install or upgrade to Windows 10.

    And do remember that MS also tells you to MAKE a RESTORE IMAGE, so if you do not like Windows 10 then you do have the ability to GO BACK..

    also Previews still show a "click to revert back to Windows 7".
    and I usually follow and take all precausions... I have more than one RESTOREABLE IMAGE of my Windows 8.1 and do have all the MSUs to upgrade Windows 8 to 8.1

    I did a few of the 'free' upgrades from OEM's on XP to Vista and Vista to Seven (and even a couple of Vista Business to XP Pro downgrades)
    All of those up/down grades involved entering the COA keys on the PC involved. And none of those keys ever activated the PC's again, only the upgrade keys worked. So looking at it that way, any COA keys you enter as part of the Windows 10 upgrade probably won't work anymore, meaning you can't go back to your old OS.

    Having said that, MS isn't going to rewrite the BIOS/UEFI on these PC's, so a OEM Key and Cert should still activate most Windows 7 PC's as they do now.

    The question is will MS deactivate the Windows 8.x keys it reads from the UEFI's during the update. :confused:

    You are getting a unhappy @Daz to read your post, he always insisted that MS wouldn't and couldn't ask people to submit COA's. :D

    btw, AFAIK, MS wouldn't touch user's BIOS, there is a risk of bricking the device, but I don't know if they would de-activate the key in their activation server.

    All right. Thank you to everyone who responded. I had already planned to create a backup image of my Windows 8.1 installation prior to performing the upgrade, I was only concerned that if I ever restored the backup image I would find my Win 8.1 activation was no longer valid. Thanks again.

    I've been wondering how MS would see a Win7 system activated by slic/key/cert with modded bios as legit or not.
    If it's a modern UEFI pc then the only time there should be a valid slic is if there was also a valid 8/8.1 Pro key also injected into the bios. That way you've got downgrade rights from 8 to 7...

    W7 BIOS mods will activate just fine, there just isn't any way for Microsoft to differ between legit and non-legit, if they had they would have already done so on W7 years ago.

    LOL, I'm not going to argue with Daz, his forgotten more about this stuff than I'll ever know. ;)

    Maybe it was the OEM that I sent it too :confused:
    All I know is I had to send to the CD Key and the Serial No. off the COA sticker to get the Upgrade Disks. And those CD Keys never activated anything again.


    I think Shenj is right, even if MS could detect a good SLIC from a Modded one. Would it be worth the trouble and risk the of 'bricking' devices to do something about it. :confused:

    Wow, that's an old post. ;)
    Its also one of the reasons why some of us were bugging the BIOS modders to use the correct SLIC's for the BIOS and Mobo combos. And were telling people to use the correct Keys for their PC maker. It would stop MS from detecting the mod, but it would make it a lot harder for them.

    I've seen MSI boards in HP, Intel & Dell. What about Foxconn? Don't even have their own slic...
