how I recover the icons?

[ametista society]

I don't get why the W10 is showing icons that seems like each other file, least pdf.

It''s horrible, pathetic, absurd, I want the old red icons back, to find the pdf files without delay.

You've set Aquivo PDF as your default PDF viewer, that's why the icon changed. Set Adobe Reader as default for PDFs again.

No... "Arquivo PDF" just means "PDF File" in Portuguese.

the default program for .pdf is Adobe Reader 9.

the problem is other.

Why are you using such an ancient version of Reader? It's not compatible with Windows 10 and there's no reason to use it. Upgrade to Reader DC and it should solve this issue.
