PowerShell and WPF GUI freeze

Question

I have a PowerShell function to look in a directory for zip files, extract it, and rename the files. The function also changes the status bar item to update what file it is on. I noticed that when this runs the GUI would freeze.

How can I get the function run and update the GUI without it freezing?

Don't do expensive operations on the UI thread -- use a background worker. Here's a tutorial: http://dotnetperls.com/backgroundworker-introduction
