Question

我使用寄存器中的搜索和Win32_Product类来获取计算机上安装的程序的列表，但是它没有提供所有程序，我已经看到C ++程序给出的结果相同就像控制面板中的程序和组件一样。是否有适用于python的api可以给我相同的结果。这是c ++ https://www.codeproject.com/Articles/6791/How-to-get-a-list-of-installed-applications的代码那就是我用的：导入win32com.client

strComputer = "."
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(strComputer, "root\cimv2")
colItems = objSWbemServices.ExecQuery("Select * from Win32_Product")
for objItem in colItems:

print("Name: ", objItem.Name)

还有注册表：

 aReg = ConnectRegistry(None, HKEY_LOCAL_MACHINE)
                    aKey = OpenKey(aReg, r"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall")
                    for i in range(1024):
                        try:
                            asubkey_name = EnumKey(aKey, i)
                            asubkey = OpenKey(aKey, asubkey_name)
                            val = str(QueryValueEx(asubkey, "DisplayName"))
                            b = "!@#$,01'"
                            for char in b:
                                val = val.replace(char, "")
                            r = len(val)
                            val = str(val[1:r - 2])
                            val2 = str(QueryValueEx(asubkey, "DisplayIcon"))
                            if s.lower() in val.lower():
                                r = len(val2)
                                val2 = str(val2[2:r - 5])
                                # print(val2)
                                subprocess.Popen(val2)
                                break
                            # print(val, val2)
                        except EnvironmentError:
                            continue

Answer 1

使用KEY_WOW64_32KEY和KEY_WOW64_64KEY检查32位和64位注册表。此外，一些安装程序将使用HKEY_CURRENT_USER，尽管很少使用后者。

请注意，pywin32的QueryValueEx返回一个元组，该元组中的第一个元素包含所需的字符串。 QueryInfoKey返回一个元组，其第一个元素是子键的总数。

def foo(hive, flag):
    aReg = winreg.ConnectRegistry(None, hive)
    aKey = winreg.OpenKey(aReg, r"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", 
                          0, win32con.KEY_READ | flag)

    count_subkey = winreg.QueryInfoKey(aKey)[0]
    for i in range(count_subkey):
        try:
            asubkey_name = winreg.EnumKey(aKey, i)
            asubkey = winreg.OpenKey(aKey, asubkey_name)
            val = winreg.QueryValueEx(asubkey, "DisplayName")[0]
            print(val)
        except EnvironmentError:
            continue

foo(win32con.HKEY_LOCAL_MACHINE, win32con.KEY_WOW64_32KEY)
foo(win32con.HKEY_LOCAL_MACHINE, win32con.KEY_WOW64_64KEY)
foo(win32con.HKEY_CURRENT_USER, 0)

稍有改进的版本，无需Win32con导入即可工作，并且可以检索软件版本和发布者。感谢Barmak Shemirani的初步回答：）

import winreg

def foo(hive, flag):
    aReg = winreg.ConnectRegistry(None, hive)
    aKey = winreg.OpenKey(aReg, r"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",
                          0, winreg.KEY_READ | flag)

    count_subkey = winreg.QueryInfoKey(aKey)[0]

    software_list = []

    for i in range(count_subkey):
        software = {}
        try:
            asubkey_name = winreg.EnumKey(aKey, i)
            asubkey = winreg.OpenKey(aKey, asubkey_name)
            software['name'] = winreg.QueryValueEx(asubkey, "DisplayName")[0]

            try:
                software['version'] = winreg.QueryValueEx(asubkey, "DisplayVersion")[0]
            except EnvironmentError:
                software['version'] = 'undefined'
            try:
                software['publisher'] = winreg.QueryValueEx(asubkey, "Publisher")[0]
            except EnvironmentError:
                software['publisher'] = 'undefined'
            software_list.append(software)
        except EnvironmentError:
            continue

    return software_list

software_list = foo(winreg.HKEY_LOCAL_MACHINE, winreg.KEY_WOW64_32KEY) + foo(winreg.HKEY_LOCAL_MACHINE, winreg.KEY_WOW64_64KEY) + foo(winreg.HKEY_CURRENT_USER, 0)

for software in software_list:
    print('Name=%s, Version=%s, Publisher=%s' % (software['name'], software['version'], software['publisher']))
print('Number of installed apps: %s' % len(software_list))
