If you can't find an app or desktop app, like Word, Excel, or other Office products, that's installed on your PC, here are a few things you can try.
If you usually start an app by tapping or clicking it from Start, but can no longer find it there, check to make sure the app hasn't been accidentally unpinned from Start.
To search for an app and pin it to Start, follow these steps:
Swipe in from the right edge of the screen, then tap Search.(If you're using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, then click Search.)
Enter the name of the app you want to find.
If you see the app listed in the results, swipe down on or right-click the app, then tap or click Pin to Start.
If an app you own doesn't appear in the search results, it might be installed on a different PC, but not on the one you're using.
To install an app you own from the Windows Store, follow these steps:
On the Start screen, tap or click Store to open the Windows Store.
Tap or click Account, then tap or click My apps.
Swipe down on or right-click to select the apps you want to install, then tap or click Install.
If the app doesn't appear in the list of My apps, it means that you don't own that app and will need to install it from the Store.
If you bought the app from the Store, but can't see it in My apps, check your billing history to make sure that the payment was processed. Apps installed before a payment is completely processed might work for a short period of time and then stop working. For more info about how to view your billing history, see Editing payment method for the Windows Store and viewing billing history.
If you can't see Account, your PC doesn't have the latest update for the Store yet. Instead, swipe down from the top edge of the screen (or if you're using a mouse, right-click), then tap or click Your apps.
