We had an experience this week that we don't quite understand loading Windows 10. One of the computers we had loaded Windows 10 on had a processor failure and the system went down. We tried to load it on a newer machine and Microsoft would not allow us to activate windows even though we had the proper windows 7 key. We know the free download program is over, but surely there is a way to reload a machine that has crashed. Has anyone run into this yet? If you had can you tell me what the issue is. This will be an ongoing problem with us as a lot of our machines average in the 6 to 7 year old range.
