提升当前进程权限

Enabling and Disabling Privileges in C++ - Win32 apps | Microsoft Docs

BOOL SetPrivilege(LPCTSTR lpszPrivilege, BOOL bEnablePrivilege) 
{
    TOKEN_PRIVILEGES tp;
    HANDLE hToken;
    LUID luid;

    if( !OpenProcessToken(GetCurrentProcess(),
                          TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, 
			              &hToken) )
    {
        printf("OpenProcessToken error: %un", GetLastError());
        return FALSE;
    }

    if( !LookupPrivilegevalue(NULL,           // lookup privilege on local system
                              lpszPrivilege,  // privilege to lookup 
                              &luid) )        // receives LUID of privilege
    {
        printf("LookupPrivilegevalue error: %un", GetLastError() ); 
        return FALSE; 
    }

    tp.PrivilegeCount = 1;
    tp.Privileges[0].Luid = luid;
    if( bEnablePrivilege )
        tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
    else
        tp.Privileges[0].Attributes = 0;

    // Enable the privilege or disable all privileges.
    if( !AdjustTokenPrivileges(hToken, 
                               FALSE, 
                               &tp, 
                               sizeof(TOKEN_PRIVILEGES), 
                               (PTOKEN_PRIVILEGES) NULL, 
                               (PDWORD) NULL) )
    { 
        printf("AdjustTokenPrivileges error: %un", GetLastError() ); 
        return FALSE; 
    } 

    if( GetLastError() == ERROR_NOT_ALL_ASSIGNED )
    {
        printf("The token does not have the specified privilege. n");
        return FALSE;
    } 

    return TRUE;
}

调用

int main(int argc, char *argv[])
{

	// change privilege
	if( !SetPrivilege(SE_DEBUG_NAME, TRUE) )
        return 1;

	return 0;
}

提升当前进程权限后，可以对其它进程进行读取、写入、改写等操作，若当前Windows用户权限够高，那么就不需要上面提升权限代码，反之则需要。
