1. Go into Windows Explorer.
2. Set it to show all file extensions (i.e. NOT to hide extensions of known file types); it's not really necessary but it helps.
3. Find a file with an extension (e.g. .jpg) you want to change the association of (Explorer Find)
4. Shift-right click on it (in the right pane).
5. Choose "Open with ..." in the right-click menu.
6. Choose the program you wish to open files with this extension with from the list (or browse to it).
7. Important: check the box "Always open with this program".
8. Click OK.
9. Go back to point 3, if you've want to change any other extension.
10. Ready.

This is quite a simple problem but i can't seem to think how to fix. I have installed software called ULEAD photo exp. which came with my digi camera and now this opens all my images, emails and everything, and it opens itself in a different window every time and then needs to close. I have set the preferences so that it shouldn't but it still messes everything up. All i want to do is reset microsoft instant viewer back as my default , but can't think how to do it. Thanks very much for any help in advance.
