Part of MyCloud software that comes pre-installed on the Asus Eee Pad Transformer is called My Desktop.
This can be used to connect to a Windows PC to remote control the computer, and also be used to synchronize your calendar and contacts between your PC and the Eee Pad Transformer.
Before you can connect to a Windows computer, you will have to download and install the Asus Eee Pad PC Suite software. Installation takes about 2mins, where you will have to set a password.
After that, you just need to run the app on the Transformer, and it should scan and find your Windows PC. Connect, enter the password you set, and you should be up and running. You can then control your Windows computer as if you were using it.
I have created a video showing it in use on the Eee Pad Transformer.
The My Desktop software can be installed on Windows 7, Vista and XP.
