Recently we posted a simple script to toggle "Hide extensions for known file types" option in Windows:
Create Simple Script to Show / Hide File Extensions in Windows XP, Vista and 7
And now we'll tell you how to add an option "Show / Hide File Extensions" in Desktop and Explorer context menu (menu which appears when you right-click) to make the task faster and easier.

In Windows XP, you'll need to right-click on a folder to get the option. In Windows Vista and 7, you can right-click on an empty area in Explorer or Desktop to get the option.
HOW-TO:
Simply download following ZIP file, extract it and run the "Install.exe" file present in the "Windows XP" or "Windows Vista and 7" folders depending upon which Windows are you using.
It'll automatically install the required files and will ask you to add the option into Windows Registry, accept the confirmation by clicking on "Yes" button and then OK.

Thanks alot for this. This is a great little tool.
However in my Windows7 64bit, I have to click refresh in order to see the change. Is it not possible to force a refresh in this tool?

Thanks a lot for the script, Vishal! :)
However, after using the script, I have to manually refresh the page (as pointed out by the person above me). Is this a bug? Can it be fixed so that the page is refreshed automatically? Thanks!

P.S. - I'm using Windows 7 (32-Bit)

Hiya Vishal, if you send me the source of the program I can add some code to automatically refresh the desktop too.
Thanks,

Thanks for this! It would be even better if you posted a tutorial on using these scripts in a submenu portion of the context menu - maybe a "Tools" submenu.
