I have purchased the Dell Inspiron-15 laptop in October 2014.
The microsoft product - Win 8.1 Pro was sold along with the PC. This was a fully embedded verion, i.e neither Flash nor DVD containing the purschased operation system were supplied.
These days all MS costomers having official version of win 7,8,8.1 are entitled to upgrade to windows 10. After having tried to upgrade my Windows to and all of a sudden I have found out that it can't be upgraded because I have a specific license named "Volume License", which has certain limitations.
I called Microsoft, they proposed me to contact "DELL" and resolve this problem by simply getting a proper product key, which entitles me to activate my Windows.
What should I do? Who I can contact about my problem?
