python实现查找所有程序的安装信息
如题,答案是:通过注册表查找。
windows系统中有两支子健存储有所有程序的安装信息:
1,HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store
以下是查找360浏览器安装路径的python代码示例:
import win32con, win32api def find_360se_path(): upper_keyword = '360SE.EXE' path = None sub_key = r'Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store' key = win32api.RegOpenKey(win32con.HKEY_CURRENT_USER, sub_key, 0, win32con.KEY_READ) info = win32api.RegQueryInfoKey(key) for i in range(0, info[1]): value = win32api.RegEnumValue(key, i) if value[0].upper().endswith(upper_keyword): path = value[0] break win32api.RegCloseKey(key) return path
2,HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
以下是查找360浏览器安装路径的python代码示例:
import win32con, win32apidef find_360se_path(): upper_value_keyword = '360SE.EXE' upper_item_name_keyword = '360SE6.EXE' path = None sub_key1 = r'SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths' key1 = win32api.RegOpenKey(win32con.HKEY_LOCAL_MACHINE, sub_key1, 0, win32con.KEY_READ) info1 = win32api.RegQueryInfoKey(key1) for i in range(0, info1[0]): key_name = win32api.RegEnumKey(key1, i) if key_name.upper() == upper_item_name_keyword: sub_key2 = sub_key1 + '\\' + key_name key2 = win32api.RegOpenKey(win32con.HKEY_LOCAL_MACHINE, sub_key2, 0, win32con.KEY_READ) info2 = win32api.RegQueryInfoKey(key2) for j in range(0, info2[1]): key_value = win32api.RegEnumValue(key2, j)[1] if key_value.upper().endswith(upper_value_keyword): path = key_value break win32api.RegCloseKey(key2) break win32api.RegCloseKey(key1) return path
