Windows Vista -- Notepad Launch Warning
During my current stay in Irving, TX along with Muthu Rajesh, he had purchased a new Dell laptop loaded with Windows Vista. While playing around Windows Vista Home Basic edition a bit, I observed some really good features. The most interesting feature I observed was when you 'View Source' on a web page, Windows Vista alers you and confirms whether you wanted to open the Notepad application.
At the first sight we would think that this is tooo much of the warning message placing more emphasis on the security. But on careful study and deducing from IE Blog, it rather plugs a hole that applications do not try having thier privileges elevated unintentionally. As IE blog explains, this also tries to address any security vulnerabilities that may be there in Notepad, which a hacker can make use of to take control of the host system.
