The NetUser Win32 application programming interface (API) component is a set of C APIs that applications can call to manage security principals that are maintained by the Security Accounts Manager (SAM). The following are examples of such security principals: set password, change password, create user, create group, set description, display users, and so on.
The NetUser Win32 API component includes the following API elements:
NetUserXXX
NetLocalGroupXXX
NetGroupXXX
NetQueryDisplayInformation
NetGetDisplayInformationIndex
There are no configuration requirements for this component.
Although the C APIs included in this component are intended for applications, internal Windows components also make use of them. Therefore, just because no application is known to call these API’s, there may be system dependencies on them. However, if the operating system is configured not to perform any security principal management (reading or writing), this component should be unnecessary.
The NetUser Win32 APIs are documented in the Microsoft Developers Network (MSDN).
