Today was Windows update day, it can do some weird things to the system. If tomorrow is better, I would just forget about it.lowdetection thanks for your answer.
I don't see any error or something in both logs.
And now it is working again, very strange....
EDIT: It must be something with VS, because when I launch portable Wise Disk Cleaner for the first time I get internet connection not detected error from VS while Wise Disk Cleaner just updated itself over that same internet connection.
