This is for Windows 7 64Bit. This started out as a touch up on another theme that was eventually deleted. After tinkering with it for awhile I decided to clean up as much as I could of what I didn't like about Windows 7 (namely, the rounded corners and other tweaks). I've also included a DLL for the explorer frame as well as the Start Menu icon "Night Light." You'll need "7 Explorer Frame Changer" and "Windows Start Button Changer V2.6" to install those. You'll also need the Universal Theme Patcher 64 to install this theme.
