....This setting is so you don't have to manually change each file individually.
1) Opening Explorer " My Documents" or (right-click on Start button and select Explore)
2) On click Tools and then select Folder Options
3) In the Folder Options Window, select the File Types Tab. This Displays the list of known file extensions and the current associated applications.
4) Scroll the list to the desired extension, for example BMP, and click to select.
5) Click the Change button in the Details section, and in the Open With window select Paint. If Paint is not listed you can click the Browse button to open a File window and locate the Paint program (%SystemRoot%\System32\mspaint.exe on my system)
6) Repeat (4) and (5) for each image extension you want Paint to handle. Note that Paint can only read BMP, JPEG, GIF, TIFF, PNG and ICO files. Any other image files will require a different application.
