如何在 python 中獲得待處理的 windows 更新？

Question

I am trying to get pending windows updates on python but no module returns me the pending windows updates, only windows update history, I don't need especifiation about the update I just need to know if there are pending updates or not, I'm嘗試使用此代碼：

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)

它返回：

我得到了所有已安裝的更新，而不是待處理的更新，如何以編程方式找到待處理的更新。

我正在使用 python 3.10

Answer 1

python 中沒有解決方案，所以我做了一個 vbs 腳本並從我的 function 內部調用。 vbs 腳本是

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

它獲取待處理更新的數量，然后我像這樣在 function 內部調用

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()

這個解決方案工作得很好。
