Windows 10: I Bought Windows 10 two days ago but still haven't been sent the key

I haven't been emailed the key and it's not in any of the emails I got confirming my purchase.I cannot figure out where Microsoft's customer support email or number is and have no clue what to do.Just made a PC for the first time and using Windows potentially for the first time and am very confused. Any help would be appreciated.

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
