Please someone of you guide me to come out of technical glitches to my laptop?

I'm Prasad. Recently I have purchased Lenovo Laptop. Actually I wanted to install in it iLEAP software and work, because we can type as many languages as possible, including Telugu and Hindi languages. But my Laptop is not supporting iLEAP software at all. So, we tried to download Windows XP "drivers", but suitable drivers are not available even for a cost.

In the meantime I received an email from Microsoft, telling that from 8th April 2014 onwards the Windows XP Support ends. This is further confirmed when I read the news "ATMs may not work on 8th April 2014, as they work with the support of Windows XP". Will anyone of you please suggest me, how I should go about now and in future if Windows XP support is withdrawn?
From one side I'm struggling in getting internet facility to my Laptop. I have shown the "Digisol" and then requested the shopkeeper for a suitable SIM for internet connectivity. He gave me an idea SIM in my name at Rs. 99/-, saying that I can get 1 GB size, 3 G internet. But when installed, it has given lot of trouble and did not work. Then I contacted the Customer Care of idea, they say that it is only for a Mobile internet and not for Laptop. Again back to the shop keeper, he says you may browse idea website, a provision for it is available.
Please advise me how I should go about to get the following:
1) I want to install iLEAP software in my Laptop and work, how can I do this?
2) How can I get internet?

First of all please upgrade your os from windows xp from windows 7 or windows 8.
