在Windows系统上，可以使用Python的pyautogui和cv2等库来实现屏幕录制功能。同时，也可以使用sounddevice或pyaudio等库来实现音频录制功能。下面是一个使用这些库实现的简单录屏工具示例：

import cv2
    import numpy as np
    import pyautogui
    import sounddevice as sd
    import threading

## Set up video capture properties ##

screen_size = (1920, 1080)
    fps = 30
    fourcc = cv2.VideoWriter_fourcc(*"mp4v")

## Set up audio capture properties ##

sample_rate = 44100
    duration = 10
    channels = 2

# Set up file names
    video_file_name = "recorded_video.mp4"
    audio_file_name = "recorded_audio.wav"
    
    def record_video():
        # Create video writer object
        out = cv2.VideoWriter(video_file_name, fourcc, fps, screen_size)
    
        while True:
            # Capture screenshot
            img = pyautogui.screenshot()
    
            # Convert screenshot to numpy array and resize it
            frame = np.array(img)
            frame = cv2.resize(frame, screen_size)
    
            # Write the frame to the video file
            out.write(frame)
    
            # Check if user wants to stop recording
            if cv2.waitKey(1) == ord("q"):
                break
    
        # Release the video writer and close all windows
        out.release()
        cv2.destroyAllWindows()
    
    def record_audio():
        # Start recording audio
        recorded_audio = sd.rec(duration * sample_rate, samplerate=sample_rate, channels=channels)
    
        # Wait for recording to finish
        sd.wait()
    
        # Save recorded audio to a file
        sd.write(audio_file_name, sample_rate, recorded_audio)

## Start recording video and audio in separate threads ##

video_thread = threading.Thread(target=record_video)
    audio_thread = threading.Thread(target=record_audio)
    
    video_thread.start()
    audio_thread.start()

## Wait for both threads to finish ##

video_thread.join()
    audio_thread.join()

在这个程序中，我们使用pyautogui库来捕获桌面截图，并使用cv2库将截图写入视频文件。我们还使用sounddevice库来录制音频，并将其写入音频文件。为了同时进行屏幕录制和音频录制，我们将它们放在不同的线程中运行。

注意：在运行此代码之前，需要先通过pip安装必要的库（如pyautogui、cv2和sounddevice）。

当程序执行完毕后，将会生成名为“recorded\_video.mp4”和“recorded\_audio.wav”的两个文件，其中“recorded\_video.mp4”是包含录制内容的视频文件，而“recorded\_audio.wav”是录制的音频文件。
