~DF16747KB.tmp.exe this is my error code how solution?

Look in the list of Startup items using Ccleaner.

Disable or Delete the line which refers to ~DF16747KB.tmp.exe

Get Ccleaner here: http://www.filehippo.com/download_ccleaner/

I suggest you only disable the line to start with, then restart Windows.
If all is okay, go back to Ccleaner and delete that same line.
