if upgraded windows 10 computer activated.

can windows 10 on old hdd?  have made backup?

if can windows there couple of ways.  1 clone old disk new disk.

another if have backup of data use media creation tool, read instructions,  , clean install reinstall data.  little trick;  if have not cleaned out copy download folder off usb.  after clean install copy folder contents new install.  use reinstall downloads rather searching on internet , having download again.
