have nothing to do with software installed or files and folders. It sounds more serious. Why did this happen? What you describe sounds like a system restore gone bad. Is this person running an AV program and have you done scans for virus and malware? Quiz your friend and find out what he was doing when this happened.
im trying to help a friend having a computer problem. his problem is that his windows xp reverted back to the settings he had several years ago. all his files are there but for example his microsoft word files wont open because windows says word is not installed. it prompts to install word 2003 when he installed word 2007 last year. i checked around online, went into his bios settings, but his date and time settings are set to this exact date. one forum i read suggested that when a cmos battery dies, it will revert to the previous installation of the cmos battery and will start again from that date. unless im missing something entirely, i need help here.
