I'll give it a try
I've got a crappy Windows 8.1 laptop that is now dual-boot Linux Mint. Windows is rarely used any more; but I'll "upgrade" it to Windows 10 if its free and give it a try. Can't be any worse than Widows 8.1 or can it ? This is assuming of course that the computer will actually upgrade as Windows update hasn't worked since last year and gives a useless error message. It must be wide open to hackers and viruses by now.
