Going by the links to the downloads, they're Technet keys/versions. No reason why they shouldn't activate and continue working in the future - never heard of any issues like that with them.
But you don't own a legitimate key or have a licensed version of Windows.
Cheers. Should be great until Microshaft get it shut down.
Microsoft have shut down the Technet programme, primarily as a result of people re-selling the keys.
