First thing I'd suggest is stop trying to make it work like Windows because it's not Windows. It's a totally different OS. It's like trying to make a car with standard transmission work like one with automatic transmission. You're just going to get frustrated and hate it.
Next thing I'd recommend is checking out the tutorials for new switchers on the Apple website. They're short and explain some of the basic differences, as well as answer many of the most common questions switchers have.
Apple - Find Out How - Mac Basics
Main things that Windows switchers have trouble adjusting to:
- The green Zoom button does not "maximize" windows, only expands them enough to reveal a window's content. There is a free tool called RightZoom that will make the Zoom button behave like a Windows minimize button in most applications.
- Closing an application's Window does not close the program itself. You must choose Quit from the applications menu or press Command+Q.
- The Finder is the Mac equivalent of Windows Explorer. You can browse through your files, change the view (list, icon or cover flow view), and the sidebar on the left gives you shortcuts to popular folders on your HD (and is customizable).
- From the Apple icon menu at the top left of your menu bar, choose System Preferences and tinker around with the options there to make your Mac work exactly the way you want it to (including enabling right-clicks).
- To delete an application, just drag it to the trash and empty it. Some large programs may require an uninstaller, and if you're not sure, just download a free application like AppCleaner to completely delete an application.
That's all I can think of to start with.
