Buying keys for $200 each is too expensive. I am going to upgrade to win 7 pro and then do the MCT upgrade to Win 10 pro. I downgraded back to win 7 HP rather than fight with them. I had successfully done this on another PC going from Win 7 HP to win 10 HD and also upgrading to win 10 pro but it DID activate. The issue was due to having a digital Product ID versus a Product Key. This was created from the MS Media Creation tool free download upgrade. I then put an OEM Win 10 Pro key and it did upgrade but it won't activate. This happened to me going from Win 7 HP to Win 10 HP. I suspect that the second one is when the Current OS is upgraded. Obviously some odd slight of hand things going on. I have my own script decoder and guess what, the first two keys give differnet PKs from the second default ProductId2. Now the surprise is finding anothjer listing of Default ProductId2 just after the first one which seems to have the same two Digital keys plus more info. Under the Win NT/Current Version there is a Default ProductId which then opens up to two DPI keys, DigitalProductId and DigitalProductId4. There is some discrepancies for finding the right digitalProductId.

I do not have a Windows 8 system to test what should be done to fix this.ģ. This gives the appearance that setting isWin8 to either 0 or 1 is not correct. The next line is expecting isWin8 to be greater than 1, but it cannot be. The check for isWin8 in DecodeProductKeyWin8AndUp() keeps only bit 0 after dividing by 6. If you allow "DigitalProductID" to be valid, this allows your code to work with other Microsoft products without throwing an exception over the lowercase 'd' versus uppercase 'D'.Ģ. Windows 10 upgraded from previous version are activated using hardware keys and can be clean installed and activated without entering any key during installation process.ġ. These codes are quite useless because you don't need to enter them. Windows 10 Pro VL-MAK - QJNXR-7D97Q-K7WH4-RYWQ8-6MT6Y.Windows 10 Home SL- BT79Q-G7N6G-PGBYW-4YWX6-6F4BT.Windows 10 Pro - VK7JG-NPHTM-C97JM-9MPGT-3V66T.This is also the reason why you are not prompted to enter the key even during the fresh install of Windows and the system is then activated properly.Īlso don't forget that Windows 10 upgrade from previous version of Windows 7/8/8.1 has generic product key that looks like this: Since Windows 8, system manufacturers can embed their activation codes into BIOS so there are no more COA labels placed anywhere on the notebooks.
