How to get rid of down arrows after updating to windows 8.1

After I updated to windows 8.1 I saw some tiles showing down arrow. I think it indicates there are updates and they need to be downloaded.  This appears only on Microsoft apps and not on others.

Following is the solution if you want to get rid of this down arrows.

First you need to uninstall Microsoft apps that show down arrow.

To uninstall apps on windows 8.1, go to the start page and then right click on the app tile you want to uninstall and select uninstall. If you are on the touch screen, touch and hold the tile and then tap uninstall.

Then go to the store and right click or swipe down from top edge. Then click or tap Your apps.

Then click or tap the app you want to install and gain click or tap Install.

Then you will see the uninstalled apps and there you can install them back again and you will see no down arrow on the tiles.

I am not sure this is something to do with Avast or not but this method worked perfectly for me.
