Fix Three of the Most Common System Problems Without Restoring a Backup

Corrupt system files, account lockouts, and accidentally deleted data are three scary computer problems that often send people running for their backup drives. While restoring a backup may technically fix things, a full system backup is usually a very time-consuming overkill in these cases, and nobody likes the time-warp effect of restoring one (e.g., if your last full backup ran a week ago). When these problems occur, fixing them can be far simpler than you might think.
