Enable Vista Aero in Windows Vista Home Basic
 

It is apparently not a big problem to enable the Vista Aero interface in Windows Vista Home Basic even though it is officially not included in that version. All you need to do is to change the values of two registry keys and restart Windows Vista afterwards. Open the registry by pressing Windows + R, typing regedit and hitting enter afterwards.

Navigate to the key Hkey_Current_User \ Software \ Microsoft \ Windows \ DWM \ and change the value of the entry Composition to 1 and the value of CompositionPolicy to 0.
