Four years ago this machine started life as a windows 7 PRO machine.. I upgraded to windows 10 and until this morning had no problems with windows product key.. The morning I found that microsoft had deactivated my perfectly valid windows PRO product key
and is saying that I need to buy a new copy of windows to get activated.. I did have a data drive ( drive F: ) fail and need to be replaced but that should not make any difference on a product key.. What kind on nonsense is this ? Now do I have to buy a new
copy of windows pro??
