Windows 8 has introduced a very significant feature ‘app store’ to download or to install some new and updated application and software to your PC. Windows 8 has an additional feature of running and installing software or application. But there are many cases when users try to download software from Windows 8 app store and couldn’t succeed. While downloading the application a message prompts which say ‘Windows 8 app store error 0x80073cf9’. In the prompting window it is typically mentioned that “Something happened and this app couldn’t be installed. Please try again. Error Code: 0x80073cf9.” After prompting of the message user gets two options either to try again or to cancel the installation. But on clicking on the option there pops up the same error message again. This made the users very stressed.
