Run "Computer Management".
Navigate to System Tools >> Local Users and Groups >> Users.
If local users other than the accounts listed below exist on a workstation in a domain, this is a finding.
The accounts listed assumes a system is joined to a domain and thus (per best practice), the local default accounts have been disabled.
For standalone or nondomain-joined systems, this is Not Applicable.
Built-in administrator account (Disabled, SID ending in 500)
Built-in guest account (Disabled, SID ending in 501)
Built-in DefaultAccount (Disabled, SID ending in 503)
Built-in defaultuser0 (Disabled, *SID unique per workstation)
Built-in WDAGUtilityAccount (Disabled, SID ending in 504)
Local administrator account(s)
* Note that the SID for defaultuser0 is machine-specific and immutable (cannot be changed). It will differ per Windows installation.
All of the built-in accounts may not exist on a system, depending on the Windows 11 version.
Fix Text (F-56675r828899_fix)
Limit local user accounts on domain-joined systems. Remove any unauthorized local accounts.
