Now they are moving to Linux and other open source project :D
ELCOT decided in favor of open-source software because of its lower cost than proprietary software from Microsoft Corp. and other vendors.
The company will migrate from Microsoft at the server and desktop levels, according to Umashankar. “My job is to save cost, and open-source software delivers the same if not more efficiency at a marginal cost,” he added.
ELCOT negotiated with Microsoft to lower the price of Windows XP Home Edition to 500 Indian rupees (US$11), but the company was not willing to cut prices on the software, Umashankar said.
