You can customise window switching using CompizConfig Settings Manager (CCSM) .
If you launch CCSM, you will find the relevant options (highlighted) in the 'Window Management' section. The 'Switcher' options are all a variation on the traditional Alt+Tab behaviour but they are much more customisable and you can use any keyboard shortcut you want.
You can enable them by ticking the checkbox next to the option. Click on the option to configure it. To get Alt+Tab behaviour you need to set the keyboard shortcut for the 'Next Window' action to Alt+Tab.
To set the keyboard shortcut, click the button to the right of 'Next Window' and follow the dialog to grab the key combination that can be Alt+Tab, Super+Tab or any other combination you prefer.
You may use any number of these window switchers but you must use different keyboard shortcuts so that they don't conflict.
make it behave more like it is in Windows 7
I have never used this operating system so I don't know how it behaves. I assume it is a window switcher with eye candy - this is what these Compiz Plugins provide.
Note: you need to run Compiz (desktop effects) for this solution to work. This requires the appropriate drivers and a sufficient graphics card to work.
