On boot up, I get Windows Media Player. Only way to remove it from screen is to minimize it

When booted up, my screen automatically goes to Windows Media Center.  When I try to close, it returns in full page mode.

I close that and I the reduced page size returns.

The only way that I can get it off the screen is to click on Minimize..

The Google Chrome and the Internet Explorer I cons have changed. They now resemble the Microsoft Icon. How ever if I hover over the icons they indicate they are Google Chrome and Internet Explorer respectively. If I click on either of them up comes Windows Media Center again.

I even get Media Center when I click on Solitaire.

I am running Windows7.

It may be I have inadvertently clicked on some thing, I have very shakes hands at times.

Oh, and I have also gained another icon named "Tablet PC Input Panel" I am not sure what to do with that.

 

I suppose you could say I am in a bit of a muddle.

 

Can some one advise this decrepit old geezer please.:
