Strange thing happening

[Blind_Arrow]

this is my very first question on the forum , problem is not crucial but annoying rather. anyway.

I had to show file extensions once as i was developing files. from then, every time i warm/cold boot my system, it always are showing file extensions, even I turn them off every time I start system.

any help/suggestions will be appreciated.
