    ok here is my situation. I have a pc with windows 7 Home premium 64-bit OEM installed on my system. I have custom built my system. My question is, oh by the way my windows 7 is still in 30 day trial mode still, so if i get a windows 7 retail key from microsoft, Can i use that retail key to activate my OEM 30day trial windows 7 to full activation mode. or I am stuck with getting a windows 7 oem key from like a place called newegg? Why i want a retail key is i can do lots of hardware changes like processor changes or motherboard changes as with oem it is restricted to the motherboard so when that goes there goes my windows 7 unless i get the same motherboard again. So when i use the retail key will i have to reinstall windows 7 to retail mode or will it take the current windows 7 oem installation already. And also if i can't use a retail key and i am forced to get a oem key. Will i have to reinstall windows 7 home premium oem in order to use the oem key that came with the software. the reason i ask is i heard each oem windows 7 disc has a serial number embedded into the program. i hope i am making a lot of since. please tell which direction i can go. thanks in advance.

    sincerely,

    I believe that it will be fine. The only difference between a retail and OEM edition is that the OEM one has a specific activation technique that is bound only to your specific motherboard so I would not worry which one you use.

    Yes, you can replace an OEM key with a retail key. Actually it sounds like you used no key since you are in the 30 day trial mode, you can use oem or retail key. You can even use retail upgrade key supposedly with a registry hack.

    I really think you can change a defective motherboard - the major problem is that you have to phone up and beg for an activation code - at least that was what happened to me the last time I had a mobo diw with a valid XP version - I don't think M$ would deny you in this scenario provided your key didn't show up on another machine later.

    Going the other way?

    Hi All,

    Along similar lines, I have a new Win7 HP desktop (SLIC 2.1 BIOS) that came with "recovery discs" that only restore the box to HP's standard, not mine. I have since DL'ed the Win7 x86 full edition ISO file and the hash checks out OK. What do I need to do to this "retail" version to make it preactivate as an OEM version would?

    TIA!

    Extract your current certificates - there is an excellent tutorial on these forums.

    Activate using basic commands - there is an excellent tutorial on these forums; OR,

    Create your own DVD - there is an excellent tutorial on these forums.

    Say no more

    The only difference, as far as I can tell, between an untouched OEM disc, and an untouched retail disc is the EULA, with no limitations on activation methods.

    If you install Professional OEM, you can activate it using any Professional key/method, including retail keys, KMS, and MAK. If you have a Home Premium OEM, you can activate it using OEM, retail, and upgrade keys.

    Very different lines actually.

    Quick Answer:
    Install Windows. Decline to enter a product key.

    Run Daz's loader, goto advanced options, BIOS mod: Install certificate and serial

    Or try backing up your token and restoring it using paymyrent's tool:

    My box is new and I haven't set it up yet (bad back). Whenever I can get it together, I'm thinking if I just let it start up normally (it will install & activate Win7 Pro), I can then back up my activation info to a USB drive. Reboot off the retail disc, partition & reformat. After the drives are set up my way, use the retail disc to install Win7 Pro, then use the backed up info to reactivate. Will that work?

    Sounds like you are wanting to do a clean install and get rid of the pre loaded crap? Yes, back up current activation with paymyrents token restore program. Boot from dvd or oem dvd (they are the same, verify hash from the repository unless you have original media), install windows, do not install key, do not check activate automaticaly. Use paymyrents token restore program to restore activation information.

    If for whatever reason you can't restore the activation then manually insert the key and appropriate cert from this site, if the site doesn't have the cert then extract it, check the stickies for information and tools to accomplish this.

    You say machine came with preinstalled OS then you say it is new self built box, if it is OEM SLP machine then yes grab certificate if not OEM but prebuilt and you want to use your retail key then use paymyrents tool as Dolorous Edd mentioned.

    Urie,

    I don't recall mentioning anything about it being a "self built box"? :confused:

    It's a new "Compaq HP500-B" minitower straight from HP that's never been started. My plan is to start it normally, let it activate, and capture my activation data. Then shut it down, boot off my "copy" of Win7 Pro (HP ships only recovery discs, not the MS disc), repartition the drive, reformat, install the Win7 Pro, and restore my activation information.

    Yeah, I kinda jumped in (thought my situation was similar). It's freaky how some threads on this forum have 12,000 posts, very difficult to keep track of who's posting what. Also a reason I always quote someone's post, no confusion that way...

    Guilty! :eek:

    Bingo! :worthy: Worked like a charm, but I used "ABRbeta" instead of "Token Restore". I saved my info with both. It looks like they function pretty much the same, I chose one over the other for no particular reason... :cheers:
