Python 列出目前安裝過哪些 HotFix (for windows)


工作原理：讀取 windows 裡面的 registry 然後將已經安裝過的 HotFix 列出來。

# -*- coding: UTF-8 -*-
import re
from _winreg import *


def subRegKey(key, pattern, patchlist):
#個數
count = QueryInfoKey(key)[0]
for index in range(count):
#獲取標題
name = EnumKey(key, index)
result = patch.match(name)
if result:
patchlist.append(result.group(1))
sub = OpenKey(key, name)
subRegKey(sub, pattern, patchlist)
CloseKey(sub)



if __name__ == '__main__':
patchlist = []
updates = 'SOFTWARE\\Microsoft\\Updates'
patch = re.compile('(KB\d{6}).*')
key = OpenKey(HKEY_LOCAL_MACHINE, updates)
subRegKey(key, patch, patchlist)
print 'Count: ' + str(len(patchlist))
for p in patchlist:
print p
CloseKey(key)
