The operating system that Microsoft painstakingly "polished" for five years, which was repeatedly claimed to be the "most secure in history," Windows Vista, turned out to be so fragile that its system login password was essentially useless! Anyone with a Vista installation CD could easily crack the Vista system login password.
In fact, if you forget your Vista login password, you can also use this method to fix it! Place the Vista installation disc into the optical drive and start the computer (if the machine is not set to boot from the optical drive, please reset it). Subsequently, the system will display a series of screens. There are no particularly complicated steps in these operations, so just follow the prompts or default settings for the process.
