We have been posting different useful tips on how to use google+ better, you can read then all here. We just got to know a company named Abelsoft which created software for windows has just created a free desktop client for google+ form which you can use google+ in a window, although it will load the mobile version of google+ which is not very useful as it does not allow you to post images in google+ and its has several other limitations.
I see no reason why would any one like to use this client of google+, which does not even load google+ web based version as shown in the image below, still if you want to try it out you can download it from the link below at the end of this article.
This software is free, but in order to start using it you will need to register for free with a valid email id where you will receive the code to unlock it and start using as shown in the image below.
It integrates into the system tray in right side of Windows Taskbar. Just click on its icon and it will display a handy window showing your latest Google+ activities as shown in the image below.
