I've run into the same prob, I had to reinstall 'doze from scratch which meant a default install of WMP9; I had previously been using WMP10. The only option offered by Windows Update was WMP11, and it didn't take me long to conclude that it blows. Totally.
You can still download WMP10 and some earlier versions here:
