My map icons are like in the picture anyone knows how to fixed this ?

Try Right Click (on a random map) - Properties - Opens with... - Choose World Editor and tick the option "always open this type of file with the chosen program". It should automatically create icons for your maps.

If you do it that way, it just opens world editor, not a map.
I fixed that problem when I had it with reinstalling wc3.

You can recreate the file associations manually.

Rather than give detailed instructions, I will point out that file type associations can be found at these two registry locations: HKEY_CURRENT_USER/Software/Classes (or HKEY_LOCAL_MACHINE/Software/Classes to affect all users). Briefly analyzing things in regedit and at those locations probably would make the unmentioned steps straightforward.

The open command should look similar to this:

"C:\Warcraft III\worldedit.exe" -loadfile "%1"

While the DefaultIcon should look similar to:
(for .w3m)

C:\Warcraft III\worldedit.exe,2

(for.w3x)

C:\Warcraft III\worldedit.exe,3

Replacing the paths with the proper paths for you, of course.

If you tried Pharaoh_'s method (though with worldedit.exe, not the other .exe) and it does not "work" (open the WE with the map), the fastest way to getting it to "work" probably would be to navigate to HKEY_LOCAL_MACHINE/Software/Classes/Applications/worldedit.exe and change the open command to the one found above (but this method probably will not give you the right icons for .w3m and .w3x files).

Then there is the option of installing Wc3. Or perhaps the Wc3 registry fixing tool can resolve this matter.
