IBitsTokenOptions::GetHelperTokenSid method (bits4_0.h)
Returns the SID of the helper token if one is set.
Syntax
HRESULT GetHelperTokenSid(
[out] LPWSTR *pSid
);
Parameters
[out] pSid
Returns the SID that is retrieved from the TokenInformation parameter of the GetTokenInformation function. If no SID is retrieved, this parameter is set to NULL.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
Older implementations effectively required that BITS users have administrator privileges in order to get the helper token SID with this method. Starting with Windows 10, version 1607, non-administrator BITS users can use this method to get the helper token SID on BITS jobs they own. This change enables non-administrator BITS users (such as background downloader services running under the NetworkService account) to use helper tokens effectively.
Specifically, the implementation has been changed to allow users without administrator privileges to get the helper token SID, as long as the SID of the caller's thread's token is the same as the SID of the job owner's user account during the IBackgroundCopyJob::QueryInterface call.
