Windows 7 Pro Occasional Error: "Invalid Product Key"

So, perhaps I should have done a bit more research on Windows installs before attempting this, but I currently have Windows 7 installed on my brand new machine (I specifically wanted W7 bc I've heard horror stories about W8 and W10) via a bootable USB drive I purchased from Ebay (I needed a flash drive bc my computer does not sport a CD drive). I also separately purchased a key from another ebay user, not questioning the validity of said user (the reviews were decent, so couldn't go wrong yeah?).

Well, apparently that is not exactly 100% gravy, because every couple of days, my computer will produce a pop-up that states "Product Key is Invalid" and prompts me to enter a different key. Upon ignoring the popup, my screen crashes and I have to reboot.

Aside from this issue, the computer is totally usable... I completed an activation, and according to the system description in Control Panel, my copy of Windows is activated and legitimate.

What would be the best way to fix this problem? Could I purchase an actual product key from microsoft or a trusted retailer? Or would I still get the same issues?

  1. Did it come with a coa sticker with the product key on it?

    No, the key was from a secondary retailer (not microsoft) and was provided in a PDF. If I replaced that key with a retail key (from a boxed W7 copy), do you think that would fix it?
  3. The problem is likely with the image used to install. Sounds to me like it might have been a pirated version they put on that usb key, which would explain why the activation is screwy. If you have a retail key you can download a copy of 7 from Microsoft and use that to try and repair the current install.

    I kept the image and current install, but used Windows Activator/loader to re-activate Windows 7. It's been a week, and no more warnings about an invalid key have appeared. Also just ran a sfc /scannow and it came up clean. Seems that one more problem out of MANY with this build has been solved haha.

    I am actually having a few other problems in relation to graphics cards and the display giving me static after prolonged sleep and/or hard reboots. I'll probably post a different thread for that though.
  5. You are now running a fully illegitimate pirated copy of windows. That activator you used is NOT legal. Where was your key in PDF format purchased? If it was from a illegitimate source like kinguin, g2a, or softwareswap theres a good chance it has been made invalid and you need to buy a new license.
  6. This, boys and girls, is why you never buy software keys from eBay, G2A, Kinguin or any other site which sells them at suspiciously low prices. The key may work at first, but it's only a matter of time before it gets revoked.

    Lesson learned. But it's not like there are easily accessible, legitimate copies of W7 laying around anymore. OEM and builder copies for custom builds are not even 'officially' supported by Microsoft.

    @bignastyid:

    Well sir, I already tried doing things the straight-laced way by putting money down on Windows 10. Turns out I just wasted $125 on malware. I dedicated MULTIPLE 6-hour troubleshooting sessions to figuring out why it would keep freezing, crashing, reboot-looping etc. Clean boot, safe mode, THREE clean installs, nothing fixed it. Why would I do that to myself again? Why would I go through so much trouble and waste more money on Microsoft? They drove my business away by selling a shitty, half-rate product.
  8. What are the specs of the system? I dont see that you posted any questions here asking for assistance with Win 10. I have Win 10 running on 3 machines with no stability issue. Had a couple driver issues with the laptop but that was an issue with a driver and not Microsofts probkem. If you are worried about the telemetry data get Anti-Beacon from spybot. You are more at risk running a cracked OS.

    I didn't make any such posts here. If you look around various enthusiast forums, there are myriad amounts of Windows 10 problem threads. I was able to find plenty of accounts of others having my same issues (freezing, driver incompatibility, crashing, random static screens, reboot loops). I already went through the ringer. Test the ram, switch out the ram, disable drivers methodically, try different versions of drivers, switch out the PSU, take out the GPU, disconnect all unnecessary peripherals, run various commands in an elevated command prompt, nuke and clean install (which I did, thrice). I really have no further interest in troubleshooting W10, as installing W7 has fixed the vast majority of those issues. Why would I waste more hours of my life when my current system is working fine now? Even if the cracked OS turns on me, I can just nuke the drive and re-install. All my precious files reside elsewhere, so if the OS takes a dump it's not a huge loss on me.
    Ask my friends in the film business who have shipped countless projects on their Hackintoshes. Seems to work great for them! Why toil over a company's product when they don't toil for the customer? It's not worth the days and weeks of headache.
