Hard disc replaced and Win10 installed.
Originally win8 purchased then upgraded to 8.1 and further Win10.
Hard dice failure and replaced. But unable to activate windows as orginally. Did not know win key since it is preinstalled and sign in with Microsoft email.
Please advise how to re activate.

Hi:
W10 should have automatically activated when you installed it.
When you install W10 and you are asked to enter a product key, you select the 'I don't have a product key' option.
If you are having further issues with W10 activation, you should contact Microsoft for further assistance.

You can find the W8 product key in the BIOS by running the free utility that I have zipped up and attached below.
