RYAN from Techrights (he is considered the jester in the IRC channels) has a new blog and in it he describes some of his problems with Microsoft, which once made him a Microsoft MVP.
Regardless of what version of Windows the user has, an Internet Explorer update is always dangerous since Microsoft continues to claim it is a system component and not a web browser. It means that at best, you need to reboot your computer, and if the upgrade goes wrong it can mean anything from Internet Explorer not working to the Windows shell failing in inappropriate ways. Internet Explorer installations and upgrades have had a significant number of cases of destroying the operating system beyond being salvageable since at least Windows 95.
No decent operating system claims the web browser is an integrated component that can’t be removed. The Internet Explorer situation is a continuing monopoly abuse and Internet Explorer itself is a relic from the 1990s, when Microsoft tried killing Netscape by forcibly installing their own web browser into Windows.
