The Windows 7 news website has posted screenshots of the new M3 build of Windows 7.

Some of the prominent changes that are visible in the Windows 7 screenshots are :

1. WordPad and Paint now sport ribbons similar to MS Office 2007. But I did not see any new features in the two.
2. The Display properties, Start Menu have also been changed to be more simpler and user friendly.
3. Windows & now bundles IE8 by default.
4. There is also a Windows Media Player Lite which appears when you click on a video file. I hope it supports more formats.
5. Various small changes in Windows Explorer & Start menu.
