Windows 7 includes a user account called the Guest account. The account is intended for any users who require one-time or occasional access to a computer.

For security reasons, the Guest account is disabled by default. If you want to use it, one of the ways that you can increase security on your computer is by renaming the account from “guest” to something else. Doing so helps prevent a malicious user from logging with the account.

To rename the Guest account in Windows 7:

1. Log on as an administrator.
2. Open the Local Security Policy editor.
3. Expand Local Policies and click Security Options.
4. Right click Accounts: Rename guest account and click Properties.
5. Type in a new name for the account and click OK.
6. Close the Local Security Policy.
