If you're like me, I love the History Killer application for Windows XP. It was one of the first applications that being able to download applications from the Internet. It was a very important function to Windows, because it was used a lot, even for basic tasks such as running a search and replace from My Documents. In fact, in some scenarios where a user would want to be able to install an application, they would need to click on the Download button on the application's website because of the nature of how some websites were designed and structured.
The reason why the history Killer worked so well was because the web pages were designed such that the application could run with the computer's security settings as "high"normal". This would allow the application to operate freely. The Windows security settings that I referred to were "home/local"applications". In other words, these were the settings that allowed the software to load and run without needing to "call home" to request permission to run. However, since the Internet was not always available when these settings were being set, this would cause Windows to have to start up the application, which would take a long time.
One way that Windows has improved over the years is by allowing the browser to help the user decide what to download to allow. It will provide a list of applications and files to download from the Internet. Of course, the application you selected would also be present on the list. When you click on the Download button, the download process is initiated. The only thing that you have to do then is wait for the download to complete. There are many applications and features that could make the process easier, but I'd like to highlight the History Killer application because it was a vital part of the operating system because it allowed you to download and run applications.
