Yes, it will be like Windows, no it will not be Windows... Ubuntu and its official derivatives are based on GNU/Linux, which is a completely different animal then Windows XP which is based on DOS, Windows 1.0, Windows 286/386, Window for WorkGroups, Windows NT, Windows 2000 leading up to Windows XP.
- Linux was from the start designed as a multi-user, multi-network, multi-tasking open system.
- The origins of Windows are in a single-user, no network, single-tasking system.
So the philosophy is completely different, and every now and then you'll run into something that just doesn't seem to make sense, but when you dig deeper, you'll notice that it does just different from what you're used to.
So, hang in there and don't despair: you're going to migrate from a mainstream boring car to a highly customized racing minivan that can do all you did before, but it's just not a sedan and any and all pieces can be customized (Want electric? Go ahead! Left rear view mirror with built-in shades? Go ahead!)
Just don't go crazy and start customizing straight away! Learn to have the tools you have, and especially have a look here on how to install software when you're a Windows user
