Hi Marianne,

One way on how to reinstall apps is by downloading it from Windows
Store. To isolate your query about reinstalling apps, we just have a few questions:

• Are you referring to the apps that have been downloaded from Windows Store? If so, what are the apps that have been removed from your device?
  
• How the apps got removed from your device?

Meanwhile, if you're trying to reinstall apps that have been downloaded from
Windows Store, we suggest that you follow these steps:

• Click Start, type Store, then press
  Enter.
• On the search bar, type in the name of the app you wish to reinstall, then press
  Enter.
• Click Free or Buy and wait for the program to install.
