I have a neighbor with and old computer with XP on it which someone gave to her. She's heard about internet hackers on TV and she wants to make the computer more secure and she asked for my help. Windows update is disabled on her computer for some reason. Can it be activated or will it make her computer unusable?
Obviously, she should buy a new computer with legal windows on it, but she can't afford it. Should I turn on Windows update on her computer or it would ask for some license key, so it is better to leave it as is? I use Linux, so I'm not familiar with updating Windows, let alone a pirated one, and I don't want to make her computer accidentally unusable.
