You can open the local machine certificate manager by hitting the windows key and typing `certlm.msc`. You can then find the self-signed certificate and disable all uses, restart the computer, and see if wget in python still works.

You can also [run wget step by step in a Python debugger](https://github.com/SlicerRt/SlicerDebuggingTools/blob/master/README.md#debuggingtools-extension-for-3d-slicer) to see what certificates it is using and from where it gets them.
