Anyway, since I have MSDN, I won't be buying Windows 10. I'll get keys when its released anyway, and ISO's to download. If I didn't have MSDN, I likely still wouldn't buy it, I'd go the free upgrade route. I have limited finances which means I go cheap most of the time.
hope now ones watching since TechNet is now defunct you are suppose to shred those old keys, I got rid of all mine ,no really I did ,honest Officer Bill ,I did ,
in 2009 I got TechNet as part of the MVP program ,and at the time tey were giving 10keys for each version and a one key Multi enterprise version of win7 and Vista
I got TechNet and MSDN as part of being a Microsoft MVP. I've done several reinstalls with those keys on my PC's with no issues. Always on the same PC they were originally used on. I went from Windows 8.0 keys to 8.1 keys but now that 8.1 will accept 8.0 keys I went back to those. I'm still testing and still an MVP so I'll keep using them. TechNet is dead but you can still log in to the site. You can't download any files or get new keys but you can look over the keys you have. I can still export my key xml file as a record of what keys I have. Anyway, that's all I'll say on that. I don't want to sidetrack the thread and take it off topic any further.
I'm not saying they don't and wont work ,I'm still evaluating them myself ,as are my employees, at The Friendly Key Society of Cape Breton
