Zing, you definitely did not experience such things before. The company handed over the computer to me as, legally named as 'ex-gratia'. If it is a gift, I probably need to pay tax on it. Sorry, I did not know in this website 'gift' has very different meaning.
I did not work for IT before otherwise I would not ask such question. I never said I worked in IT in this thread. What I said was in such dreadful situation, you would never ever ask company's IT people to reinstall anything for your 'ex-gratia'. That would be insane
I cannot create a new user, tried and failed.
I cannot log-on to local as well, although I rememered I did it before.
Anyway, I am quite clear of what I can do. I probably use it as is and being the last employee for ever.
