Need help with win 7

just got my new puter with windows 7 installed.
Today I have just about destroyedit already?
It's a Sony Vaio touch screen and somehow I have managed to turn all
the icons into this message when I try to open anything:
"Windows Photo Viewer can't open this picture because Photo Viewer doesn't
support this file format, or you don't have the latest updates to Photo Viewer.

I seem to have hit the wrong button while trying to open a photo and made a total
mess.

I am new to windows 7, and hoped it worked like XP, but it looks more like Vista.

Does anyone have any idea how I can get this back to normal?

Would greatly appreciate any help.

Thanks,

Dumb in Texas

I'd call Sony tech support:
Sony 1-888-476-6972 (usually these responses get me to tech support: 2,2,2,1)
Extended hours support - 1-239-768-7603

...vmars (Texas too)

Thanks Vmars, I tried them earlier and got tired of waiting, guess I'll try again
tomorrow.

Glad to be in TEXAS and no where else! Have to feel sorry for those
eastern folks...
