Answer 1

BOOL IsAdminMode()
{
HANDLE                   hAccessToken;
    BYTE                     *InfoBuffer;
    PTOKEN_GROUPS  ptgGroups;
DWORD                    dwInfoBufferSize;
    PSID                     psidAdministrators;
    SID_IDENTIFIER_AUTHORITY siaNtAuthority = SECURITY_NT_AUTHORITY;
    UINT                     i;
    BOOL                     bRet = FALSE;

    if(!OpenProcessToken(GetCurrentProcess(),TOKEN_QUERY,&hAccessToken))
goto cleanup;

    InfoBuffer = new BYTE[1024];
    if(!InfoBuffer)
goto cleanup;

bRet = GetTokenInformation(hAccessToken,
TokenGroups,
InfoBuffer,
1024,
&dwInfoBufferSize);

    CloseHandle(hAccessToken);

    if(!bRet)
goto cleanup;
    if( !AllocateAndInitializeSid(&siaNtAuthority,
2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0,0,0,0,0,0,&psidAdministrators) )
goto cleanup;

    bRet = FALSE;

    ptgGroups = (PTOKEN_GROUPS)InfoBuffer;

    for(i = 0; i < ptgGroups->GroupCount; i++)
    {
        if(EqualSid(psidAdministrators,ptgGroups->Groups[i].Sid))
        {
            bRet = TRUE;
            break;
        }
    }

    FreeSid(psidAdministrators);

cleanup:

    if(InfoBuffer)
delete[] InfoBuffer;

    return bRet;
}
