WP7 Remote App Lets You Control Your PC
It comes with a server side application that lets you scroll through your files, launch them, close them, minimize them or maximize. There will also be user defined key combinations and various commands. DeathLamp also plans to add a feature later on that would allow the transfer of files from the PC to the phone to be done remotely.
If all that sounds good, the bad news is that the app is still currently in development but for those who are interested you can check out the application thread for more details regarding updates and progress. The good news is that the app will be free, but no word on when it will be available.
