Windows 10: All the apps/games have shrunk but nothing else has. Home screen

I do not know how to fix this, I was playing A game and I must've hit a shortcut. Please can you help since the apps and games are small but nothing else, It looks odd.

PC screen turns on but does nothing else.

Windows 10 home (with latest updates)

On our other PC.
I believe that something went amiss during the virus scan over night.
This morning the PC was off when we normally do not shut it down.
After I pushed the start button, the screen came on but nothing else worked.
I changed the batteries in the mouse, but that did not make a difference.
What should be my next step to try to activate this PC.
BTW, I did not hear the fan come on.

 

Desktop screen has shrunk - need to restore to original

I downloaded an app from Big Fish - after downloading it, my desktop screen now has shrunk (2 inches of black screen on each side) How can I restore the original desktop size?

 

The 'Photos' app for photo viewing has disappeared.

I do not understand this, when I returned to the PC later today my original settings had returned to the start screen, including one other tile which I had also lost but had not yet re-instated. Also the original list of 'All apps' had returned to the start
screen, including 'Photos'. There is nothing that I am aware of having done that should have caused the original disappearance of some apps from the 'All apps' list and their associated tiles, or that could have caused them to return.

It has therefore been unnecessary to follow your suggested steps, though I have done so anyway and it works as suggested. Note that I had followed your steps 1 & 2 earlier which is why I knew 'Photos' had not disappeared from the PC but was simply not
visible on the 'All apps' list and hence my inability to re-pin the tile.

Thank you for your reply and understanding my frustration.
