All programs/files ect opens with the same program?

[Spphy]

I have a small problem here. This morning when I opened my computer every program and file (exept for folders) opens with Windows Picturewieving.
Then I ofc changed my world of warcraft to what it should normally open (The launcher) And now... All my programs opens the world of warcraft folder. All hotkeys ect. Everything!
Help! :s
How do I make them all normal again..

What operating system are you using?

I suspect you've accidentally changed the default program to open all file extensions with.

Control Panel\All Control Panel Items\Default Programs

Should help you out.

I fixed it by setting my operation system back (you know setting it back to what it was like 3 days ago) fixed it
