I am using composer with Windows, and it was working great, but this week, the composer just gets stuck on the update, it just get stuck at any final task.

For example:

When updating: it get stuck in the "Generating autoload files" message.

When self-updating: it get stuck in the "You are already using composer version 1.4.1 (stable channel)".

I tried older Versions of composer, but they all get stuck at the end.
