Png thumbnails dont appear correctly

[SevenDragon]

Hi.
Since some time my png thumbnails doesn´t appear in explorer. All the other image file types are fine.
I tried changing the default program to open png files but it remains the same.

I tried rebuild icon cache without success.
What can be the problem?

Try deleting the current thumbnail cache and let it rebuild. Make a system restore point before as a precaution.

You can also disable and reenable

What program are png's associated with now? You can also try associating them with another program or windows own, and see if the problem continues.
