Windows 10: White tile box on screen?

Hi unfortunately I'm not in the same area as this pc. My sister's boy has been enthusiastic with downloads. He thinks he has downloaded something he shouldn't. He's only 8!Unfortunately my sister has no IT skills.It's possible he has hit some random combination of keys or indeed downloaded something. Please see attached screenshot. This white box is appearing now on the screen. Any clues before I ask her to take it to support please ?

Start menu White box tile


If you would like to use one of these for your start menu tile, let me know. I will need the exact spelling and capitalization of the .exe file. For example for Macrium Reflect it's "reflect"(without quotes).










You will get a tile pack with the png icon renamed and a manifest.xml file, you need to place in the folder with the .exe file. Then delete the shortcut and tile like I told you earlier, then you just right click the .exe and pin to start. Remember it is important to delete the icon in C:\Users\YourName\AppData\Roaming\Microsoft\Windows\Start Menu\Programs first.
