The whole world had an eye to see the “Monad” (also known as MSH, is the replacement for the simple command shell in the current versions of Windows) in Windows Vista aka Longhorn.
Microsoft initially planned to include Monad in Vista. However, Microsoft dropped to include in Vista due to a security threat.
But, according to Stephen Toulouse from Microsoft Security Response Center Blog!, Slashdot article incorrect about this virus threat. Also, he wrote in another blog that, “Monad” is not included in the beta release of Windows Vista or in Windows Server 2003 R2, nor they have any plans to include in the final version of Windows Vista and there is no relation between Monad and Windows Vista Beta 1; But considered for the Windows Operating System platform for the next three to five years.
In addition to Yahoo! mail, I would like to add to the list that Wells Fargo online access is also not supported for IE7; and I get the following error.
For Online Access with Wells Fargo You Must Use a Supported Browser
Wells Fargo no longer supports the browser version you are using. Please upgrade to a supported browser in order to get access to Wells Fargo’s secure sites
Its bit surprice that the web developers are having a upper check on Versions; means if one releases something with major version change lets say from 6 to 7 in case of IE even without any functional change, the web site will not work. hhhh…

This is a surprice that Yahoo! mail has a check on Browser version, and due to this version check we can not check Yahoo! Mail using Internet Explorer 7, which is part of Longhorn. I did not tried with IE 7 on XP. In a side note, GMail works perfect.
Here is the error and screen shot.

For the first time since its introduction, Firefox has lost ground in its attempt to woo users from Microsoft’s Internet Explorer, according to NetApplications.
May 2005 Browser/Market Share:
Microsoft IE - 87.23%
FireFox - 8.06%
Netscape - 1.64%
Safari - 1.91%
Mozilla - 0.58%
Opera - 0.51%
Other - 0.07%
As Internet Explorer 7 is also released under BETA, which offers the improved security and tabbed browsing feature that Firefox has, one can predict Internet Exploer 7 will sweep the surfing market in the coming days. You can view the screen shots of IE7 on Longhorn from here
Internet Explorer 7 Reviews:
This is a simple observation that I made in Longhorn BETA1. Every time, I boot to Longhorn, the Windows Security Firewall Alert pops up during the startup stating Whether to block AVG E-mail scanner or not. Something funny, and do not know how to turn it off (you can find the screen shot below for reference). Note that I do have the same AVG Anti Virus (7.0.338) on XP professional; and I never got any alert except during the install and first startup.

Do you have any idea ?
Thanks
