Opening a Window in a thread that is not UI thread is not recommended at all. You can open a popup window using Show() (modeless) method or ShowDialog() (modal) method. In Window2's load method, you can start a new thread which does a complex operation and once it is done with the operation, it can show a dialog.

Now, while in a different thread than UI thread, if you want to show any UI (dialogs, windows) or change existing UI (textblock, etc), you must use Dispatcher.Invoke method.

You need not open the window in a thread. Once you've opened Window2, start a thread for the complex function in the Window2.Loaded event handler. This will leave your UI undisturbed.
