"How to do [task]?"
I've seen that most often from people of Indian origin. Not so much from Pakastanis though.
Around 5-10 years ago I used to commonly see "I have doubt on how to <XXX>"[1]. I don't see it quite as often now days.

I strongly suspect that this has arisen from Google searching, where people naturally write their queries to complete the sentence "I would like some information about ________."
