Problem description: Built a new PC a couple months ago, everything working great until I boot up today and get the "This copy of windows is not genuine" message, error: 0XC004F057. I have a product key but when I type it in it's coming up as not valid. Attempted fixes: uninstalled a couple recent windows security updates, then re-installed when that didn't solve anything. Google didn't provide too much helpful info other than "enter your COA". I've re-entered the key with no change in results. Recent changes: No recent changes -- Operating system: Windows 7 Ultimate SP1 64-bit System specs: ASUS Sabertooth Z97 Mark2, Intel Core i5-4690k, Samsung SSD Location: US I have Googled and read the FAQ: Yes

Did Windows activate properly using your key after you initially installed it?

When I first installed I don't remember it asking me for the key, but otherwise everything went smoothly.

Are you 100% sure that the key you're installing from is valid and appropriate for the disc you installed from? Windows does not prompt you for a key when you install, you have a 30 day evaluation period to activate Windows using a product key after installation, which can be extended twice for a total of 90 days. Your symptoms match what happens if you don't use a key that is valid for the version of Windows you installed. E: Just to be explicit, if you are using an MSDN key that did not come on a COA sticker that you either bought or someone gave you, it will no longer work with Windows.

I'll triple check.. was afraid that might be the case. Thanks for the response! If in the event that I need to purchase another would I have to re install the new copy of windows or could I just enter the new key to validate the OS?

You shouldn't need to reinstall as long as the COA is for the version of Windows you have installed - Windows 7 Ultimate SP1 64-bit. You couldn't use a COA for Windows 7 Home Premium 64-bit, for instance.

Alright, I definitely have a genuine copy and genuine key, yet this error keeps coming up (0xC004F057). Is it possible it's from corrupt files? I'd do a system restore but the furthest back restore point I'm seeing is after the issue came up a couple days ago.

Can you try just reregistering the key? From an administrator command prompt: slmgr -ipk (your windows key here) slmgr -ato If it returns an error, you might at least be able to narrow it down.

If that doesn't fix it, confirm you installed fresh from correct media that matches the key you're using. It's entirely possible you have valid media and a valid key that are not valid in combination.
