These product keys can be used to activate all preview builds of Windows 10 that are officially released by Microsoft, which also means that the key might not work on leaked Windows 10 builds!
Note that the above mentioned Windows 10 product keys work irrespective of the architecture of Windows 10, meaning they support both 32-bit and 64-bit. Just make sure that you’ve typed the 25-character correctly, without any mistakes. Note that all these Windows 10 product keys are offered by Microsoft.
