In Windows 7, it is possible to “pin” an application to the TaskBar so you can open it with just a single click. To pin something, simply drag the icon to taskbar and click on the “Pin this program to the Taskbar” popup menu item.
I do this with my Visual Studio shortcuts to save time hunting on my desktop or in the Start Programs menu.
Below is an awesome tool to use if you are planning on installing Windows 7 on a machine that does not have a DVD drive. This tool allows you to put Windows 7 on USB drive and run Windows installation from there.
If you got one those netbook with XP on it and the machine has at least 1GB RAM and 1.6 GHz, I would format it and install Windows 7 on it.
