It was just by sheer luck that I came to know that SBI ATM’s are using Windows, to power it on. Woh!. I went to an SBI ATM to check my balance wherein I found that all the touchscreen utilities etc. are being loaded by Windows XP. Mostly the machine consisted of 2 partitions, C and D, In D there you had the files/bank details (did not opened any one of them) while the C drive had the configuration files. It worked like a normal touch screen PC, restarting, powering it off etc. One of my colleague then called up the helpline number that was printed just beside it to have the ATM checked.
