It has been reported that Microsoft has made three dozen changes to its Windows 7, since it released a public beta of the software more than a month ago.

Chaitanya Sareen, senior program manager, in the company's long "Engineering Windows 7" blog, claimed that Microsoft has made three dozen (36) improvements and modifications to its new operating system Windows 7 to develop the "release candidate" of the OS.   

Sareen revealed that Microsoft has made 10 changes to the Window 7 desktop, 4 to OS's new touch-sensitive features, 4 to the Control Panel and 8 to Windows Media Player. According to Sareen, many of the changes are too small to be spotted, while some modifications are easily spotable.

Sareen elaborated that the developers have squeezed up to 39% more icons on the taskbar. Sareen wrote that Microsoft has squeezed up the Windows 7 RC to open up between 24 percent and 39 percent more icons before the taskbar scrolls.

In the Windows 7 RC, Sareen wrote, the programs will automatically be displayed at the bottom of the Start Menu, where users can launch them or add them to the taskbar.

Sareen wrote, "If you've been following this blog, then you already know about a recent design change we've made that will prompt for any modification made to the [User Account Control] Control Panel."

In order to address security issues raised by Windows 7 beta testers, Microsoft has changed User Account Control in Windows 7. According to Sareen, the Windows 7 RC will improve audio reliability, add support for FAT32 hard drives and bring native support for .MOV files -- the video format that many digital cameras use -- to Windows Media Player.

Sareen articulated that to make the Windows 7 RC more noticeable, Microsoft has changed the flashing open window effect in the OS. Now, the window, colored in orange, will flash seven times.

It will now be easier for users to find and connect to networks through the taskbar in Windows 7 RC. Microsoft has added a new overlay icon, which indicates when there is a local connection without Internet access.
