Many developers want access to as much data as possible. This is part of the reason why so many apps request permission to access seemingly everything one could have on their device (with the other part being developers' need to sell ads). But what happens when the apps don't ask permission? According to .NET developer Sebastien Lachance, this is what happened with versions of Windows 10 released prior to the yet-to-be-relaunched Windows 10 October 2018 Update.

The developer noticed that his enterprise app stopped working after Microsoft released version 1809 of Windows 10. It turns out that's because the app required access to specific folders, and this was the first version of Windows 10 that didn't grant that access by default.
