Thankfully, this default behavior can be changed, but there are some important caveats to the process. By default, Windows Store apps, games, and media content will be installed to the user’s primary Windows drive, even if other storage drives are available. While users can still change the installation directory of traditional Win32 apps, there are no such options while installing Universal Windows Platform (UWP) apps from sources like the Windows 10 Store. With Windows 10, however, Microsoft is beginning to take a more centralized approach to application management.
This allowed, for example, gamers to install their PC games and emulators to a dedicated gaming drive, or for those involved in media production to install video and photo applications to fast SSDs and storage arrays instead of their default “C:” drive. Historically, users could almost always manage the installation of traditional Windows applications by changing the install directory via the application’s installer program.
