A specified user account defaults to a standard user after the Out-of-Box Experience (OOBE) process is complete on a computer that has hotfix 969902 installed
Consider the following scenario:
- You have a computer that is running Windows Vista or Windows Server 2008.
- You specify a user name that is exactly 15-bytes. This user name includes double-byte characters during the Out-of-Box Experience (OOBE) process. For example, you specify “?????12345” as a user name.
- You use the default computer name when you proceed to the next step of the OOBE process. For example, you use “?????12345-PC” as the computer name.
In this scenario, the specified user account defaults to a standard user after the OOBE process is completed. Therefore, the user cannot execute some operations that require administrator permission.
