Changing the default install location of these apps is an excellent example. Although they didn’t want to change too much about how the traditional programs and apps work, the new features that they introduced are much more straightforward to tweak. If Windows 10 has made one thing easier, it’s tweaking its new features. Whether this was a smart move or not is debatable, but making sure that all Windows Store apps are installed in one place can help you make better use of your storage. Microsoft has come up with this in order to emphasize the responsive design of their tablets and mobile phones. First of all, the way they’re installed and downloaded is more akin to using a smartphone store. Windows Store apps are built completely differently than Win32 apps. All of this is very easy to do on Windows 10. Unusually demanding apps are best installed on SSD drives, so you may want to set the fastest drive as a default for apps.
The most typical reason to change the default install drive is that you are running out of storage space, which is especially common on laptops with SSD drives.
