I did a clean installation of Windows 10 and when I open folder with PDF files in it, the File Explorer start flashing!?!
Also it pdf files can't associated with another program but Microsoft Edge.
1. Microsoft Edge was default program for opening of *.pdf files;
2. Than I installed Adobe Reader, but the problem continues...
3. I tried everything to do it in Settings panel (part 1 & 2) or Command prompt (part 3)...
4. Then I go to registry editor, erased the current pdf reg., and close the editor.
5. After that I associated .pdf file to Adobe Reader by common way and it is done!
