I could go on and on forever writing questions and you could also go on and on searching for "Desktop Support Engineer Interview Question," but the fact is that if you are going for L1 (level 1) positions, you only need to do your basics well.
You have had the training, practicals, and stuff like that, now answer the questions in your own words. Simply mugging up the answers will a be a recipe for disaster.
A quick Google search of the question will reveal all the answers. Surf for the answers and in the process you'll learn, and once you learn you won't forget at the time of the interview.
Besides fact-based questions you will also be tested on your practical skills. They could ask you to do the easy task of installing the operating system in front of them or even ask you to solve a problem faced by a user right there.
Get properly dressed and don't excessively stare at the receptionist (lol).
