Still a newbie here myself and on Mandrake 10, so it may be a bit different, but to get the windows to minimize in the taskbar, just right-click the task bar at the bottom and choose ADD - APPLET. There choose 'task bar' or 'system tray' or something like that... One of them options makes the windows minimize like in windows....
Other than that, there's also a graphical interphase that mimics the MS windows thing.... I haven't tried it so I don't really know how well it mimics....
Go to CONFIGURATION - CONFIGURE MY COMPUTER then something where you can configure your login, and there you can find a pull-down menu with all different graphical modes. If you installed all those different modes during the installation, one of them should be the one that mimics Windows....
Like I said, I'm a newbie, so don't shoot me if none of this works...
