Windows 10 License Number On My Pc

Please can anyone tell me whether my windows licence number has changed now I have upgraded to Windows 10 and where I can find the new number if it has? I have had a telephone call telling me my computer is sending critical error reports and, as I have these quite regularly I was going to hang up but when I asked I was given a licence number by the caller which they do not normally do. However, I cannot find this number on any of our computers but wondered whether the one which is now running 10 may have changed or whether this is just another hoax call to try to get access to my computer. Hope someone can give some assistance or suggestions.
