WPF application has old look (like win forms) in 2008 R2 server

Question

After I uninstalled a third party product from VS 2013, any WPF app now looks like the old win forms. Before it was working fine and had the modern look of WPF. I went in Control Panel clicked the VS 2013 and clicked on Repair option. After awhile it completed successfully but made no difference. I want the modern look back.

UPDATE:

Ops! What I said above was not really the problem. What happened is that I ended up working on a remote 2008 R2 server (via RDP) and I found the answer here

Answer 1

The link to the answer is in the question's update section. The problem was not with VS 2013, but the remote server that needed to be setup properly.It looks awesome now.
