Windows active desktop is a feature that allows you to embed a browser window (viewport) on your actual desktop. Instead of a window form, it’s accessible anytime on the desktop yet never takes up any task bar spaces.
Windows XP users can activate active desktop following these procedures. Basically you just right click on the desktop and select Properties to open Display Properties. Go with Desktop tab, click Customize Desktop and select Web tab in the dialog form.
Create a channel for Twitter by clicking New. Type in http://twitter.com/home for Location and click OK.
It starts to synchronize for this new web item. After a few seconds you should be good to go. Just make sure Twitter / Home is checked for display.
You may notice that there’s a nicely embedded browser window of http://twitter.com/home on your desktop now. Move it around and place it somewhere handy after resizing it a little bit to fit the screen.
Isn’t that great! You can start posting twits from there from now on or if you can’t chances are you haven’t logged in yet.
