1)i) Why keep english because windows itself is programmed in english (Microsoft who are american so it keeps English US) and the other lanaguages is just for display so the interface can be used around the world but the coding and everything done in the background is still english coding, just the interface (what you see) is different) ii)I think microsoft tend to release beta versions to japanese earlier than the rest of the world or maybe you just forgot to remove it 2)Username is what you see on the login page Fullname is what you see at the top of the start menu Password type is where you type in the password you want for the account in and confirm is just the same as the first box if you dont want a password then select blank password or just leave the password boxes empty, anyone will do. blank password is where you can jsut click the username and it will enter the user account without asking for a password, if there is only one account on the computer then it will automatically log into the computer 3) Computer Name - Name of the computer, used mainly for networking to find your other computers on your network Full Name - Enter your name Organisation - name of your company i.e. Microsoft, i usually just put Home Workgroup - this is the name of your network, a good way of describing it is a folder(Workgroup) with files in it(each file is a computer), if you have a workgroup then you cannot join a domain at the same time so domain is disabled, so dont use domain. if you leave any of these blank it will just ask you for the answer during the install so you do not need to answer them all The 'Fullname' and 'Organisation' is shown on the system properties tab (right click on my computer and select properties)
