In the past, people have been downloading applications from different sources for free; it's no longer so easy to find an application that is free to download. The biggest source of free applications has been the internet. Some of the popular sites online is the Windows Store and AppExchange. The Windows Store is always free to download but as a matter of fact, you should be careful in downloading applications from there because of malicious applications that use the System file paths to execute arbitrary commands. Because of this security feature, most developers do not publish their applications to the Windows Store and because of this the Windows Store is also regarded as unsafe.
The best source of software for Windows is the Internet. Most applications that can be downloaded for free are offered by Microsoft as part of the Microsoft Application Packages (MAP). But the MAP must be used properly, and the program is limited in terms of the software it can offer. The application can be used to download files to your computer, but it does not provide the software that is required to run the application. There are other free software available on the internet that you can try and the best one is the Windows Story Studio software. You just have to register to download the package. The installation of this software is done by clicking on the link that's located in the webpage and that's it.
Another problem is that if you are searching for free downloads on the internet, you should not choose to download the very same application that is going to be installed on your computer. This way, your system may not receive the latest updates that are needed.
