My ProblemMinor problem with upgrading to Windows 10 from Windows 8.1 on a new laptop. For reasons which I shall not bore you with the Microsoft account login details were thrown away. So at the moment the laptop is an expensive brick. As there is no data on the machine the plan is to reinstall Windows 10. The problem is; what is the product key for the Windows 8.1 OS, so that a free install can be made? I have successfully used the following Comand Prompt string to recover the key. Will a reinstall of Windows 10 solve the access problem?
