1. Windows 7 Ultimate 64 Bit Product Key
2. Windows 7 64 Bit Product Key Purchase

Windows is funny. My win10 died and I put old win 7 64bit on that HDD and used the product key from the install CD.

Activate your copy of Windows (without a Windows 7 Professional product key) Click on the Start button in Windows. Open the Run app. A dialogue box will appear where you can enter text. Enter ‘CMD’ and hit Enter. A new window will appear where you can enter commands (CMD). Enter ‘slmgr –rearm’.

Worked fine but I found out that it was the actual HDD which was damaged. So I bought new HDD, put new clean install of win 7 from the same CD. The product key which worked on the old HDD yesterday didn't work on the new HDD today (same installation from the same CD. Don't understand it.) Nevertheless, the first key from here (6RBBT-F8VPQ-QCPVQ-KHRB8-RMV82) worked just fine.

So, I have no clue what's the deal, but it works now and I'm happy. Thanks for the codes.
