I have acquired a dell computer with Windows XP. I own a custom built computer with Windows XP. I don't know what would be my best option to get them to share my internet connection. Should I just clone my existing hard drive. I ask because I also have a laptop with Windows 10 and did not bother networking it. I just use a flash drive to update common files. I would prefer the easiest way to accomplish having 3 independent computers able to access my one internet (DSL) connection.
