After submitting my work , after several months it happened.
Can anyone here please help me in advising and guide me to appeal to university regarding these allegations for Academic Misconduct?

Contact student welfare office or your student union.
Do you have a personal tutor - if so try them.
Get all the info you can on your uni's policies and procedures. Find out exactly what you are accused of and the relevant regulation you convened. If your going to work in business administration this is the sort of tangle you will come across and need to work out.

I'm sorry but from what you have written I'm not really clear what the particular issue is.
"Academic misconduct for my work regarding the File name" - what does that mean exactly?
"as I have used my friends laptop" - Exactly how does this become an issue?
