With Aero there are couple of nice things you can do.

1. If your computer is not so much up-to-the-specs for running those transparent windows, you can easily turn the transparency off:

1. Right click on the desktop and choose "Personalize"
2. Click on the first option at the very top: "Window Color and Appearance"
3. Uncheck "Enable Transparency"

2. If you haven't noticed, Vista has some nice menu animations but for someone's taste - they may be a bit too fast or slow, or simply too much. There is something that we can do about this:

1. To turn them off completely go to Start menu and run the following: SystemPropertiesPerformance (for easy access), or if you like to click around right click on your Computer, choose Properties, click on "Advanced system settings", and under the "Advanced" tab you'll have the Performance Settings. (there are actually other ways of getting here too)
2. Once in Performance Settings, under "Visual Effects" uncheck "Animate windows when minimizing and maximizing".

3. If you like the animations so much, you can slow them down so you can see them longer (why would you want this?):

1. Click on Start menu. Type regedit then hit OK.
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
3. In the right hand pane, right click on an empty space and from the context menu that appears choose “New > DWORD (32-bit) Value”.
4. Give the new DWORD (32-bit) value a name of AnimationsShiftKey (be careful in spelling this!)
5. Double click on the new DWORD value and give it a value of 1. 
6. Close the Registry Editor and log off of Windows and log back in for this to take effect, OR run net stop uxsms at administrative rights command prompt followed by net start uxsms to restart the DWM engine. When you want to see the slow animations, hold the [Shift] key :)
