I can't speak for other countries, but certainly in the UK company directors are personally liable for unlicensed software being used in their company. As a result, most companies once they get to a certain size have pretty draconian software policies and centralised licence administration. My last employer even had spyware installed on all company PCs that looked for unlicensed software and deleted it. So if it was something you'd bought yourself it would only get deleted anyway as it wouldn't be in the central licence database.
