Windows 10: Couldn't Download - Network Issue

This error is occurring since the first time I upgraded to windows 10 from windows 7. Basically, I am unable to install any file from a browser. Whenever I install any file, it just says Couldn't download - Network Error. This is ruining the whole Windows experience as it was supposed to be good and easy to use. I am unable to do anything right now, can't install apps from the browser, anything that needs to install data from the internet doesn't seem to work. Although, apps which I am installing from Google or Microsoft are getting installed easily. This is not a network or hardware error mos
