Yes ... windowblinds with some mac theme enabled can do it .
Alternatively, some visual styles of mac clone comes alongwith explorerframe.dll that is like your screenshot . You may replace those with your existing ones .
If you want to go through the second option
1 . Download a mac clone theme from Browsing Visual Styles 7 on deviantART
( I recommend either Snow-Leopard-for-Win7-Beta2
2 . Take ownership of explorerframe.dll (C:\Windows\System32\explorerframe.dll) , and make a manual backup of it .
3. Replace the existing one with the downloaded one .
CAUTION .... Backup Complete Computer - Create an Image Backup
, and to restore the backup, you need either Windows 7 installer DVD , or Download Windows 7 System Recovery Discs — The NeoSmart Files
. Without having these two, dont go for a sustem file replacement , it may be risky .
