I was doing some research on making "the jump" from Windows 7 to 10. As for background information I found the following articles:
http://arstechnica.com/gadgets/2015/07/how-to-do-a-clean-install-of-windows-10-from-windows-7-and-8/
However, both are not very clear about the difference between an old skool clean install (completely wipe partition and do a fresh install) or the offered solution by the setup "Choose what to keep" -> "Nothing".
Does the latter option keep files/registry items or anything like that in place besides the .old windows files?
