【问题描述】：

我正在尝试在 python 上获取待处理的 windows 更新，但没有模块返回待处理的 windows 更新，只有 windows 更新历史记录，我不需要关于更新的 especifiation 我只需要知道是否有待处理的更新，我正在尝试使用此代码：

from windows_tools.updates import get_windows_updates
import os

for update in get_windows_updates(filter_duplicates=True, include_all_states=False):
    print(update)

我得到了所有已安装的更新而不是待处理的更新，我如何以编程方式找到待处理的更新。

我正在使用 python 3.10

【问题讨论】：

是否将include_all_states 设置为True 会列出待处理的那些？
不，它没有，我的解决方案是创建一个 vbs 脚本来创建一个包含待更新数量的 txt 文件，然后在 python 中使用该 txt

标签： python python-3.x windows

【解决方案1】：

python 中没有解决方案，所以我做了一个 vbs 脚本并从我的函数内部调用。 vbs 脚本是

Set updateSession = CreateObject("Microsoft.Update.Session")
Set updateSearcher = updateSession.CreateupdateSearcher()        
Set searchResult = updateSearcher.Search("IsInstalled=0 and Type='Software'")


If searchResult.Updates.Count <> 0 Then 

For i = 0 To searchResult.Updates.Count - 1
    Set update = searchResult.Updates.Item(i)
    
Next
End If

Main

Sub Main()
    Dim result, fso, fs
    result = 1 / Cos(25)
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set fs  = fso.CreateTextFile("output.txt", True)
    fs.Write searchResult.Updates.Count
    fs.Close
End Sub

它获取待处理更新的数量，然后我像这样在函数内部调用

import subprocess, time, os


class update_monitor():
    def __init__(self):
        self.output='output.txt'
    
    def updates_restando(self):
        os.system(r'script.vbs')

        time.sleep(10)

        with open(self.output,'r') as file:
            for i in file:
                if i == '0':
                    print('Não há atualizações disponiveis')
                    return 'Não há atualizações disponiveis'
                else:
                    print('Existem atualizações pendentes')
                    return 'Existem atualizações pendentes'


a = update_monitor()
a.updates_restando()

这个解决方案效果很好。
