python-读取、修改注册表信息

注册表分两部分：键和值

键是一个树结构，一个键下面可以有很多子键

方法	解释
RegOpenKey	打开注册表项
RegQueryInfoKey	检索有关指定注册表项的信息
RegQueryValue	检索有关指定注册表项的信息

查询键值

import win32con,win32api
def get_Reg_key(path,key_):
    # coding:utf-8
    reg_root = win32con.HKEY_LOCAL_MACHINE
    #reg_root = win32con.HKEY_CLASSES_ROOT
    reg_path = r'%s' % path
    reg_flags = win32con.KEY_READ | win32con.KEY_WOW64_64KEY
    # 读取键值
    key = win32api.RegOpenKey(reg_root, reg_path, 0, reg_flags)
    value, key_type = win32api.RegQueryValueEx(key, key_)
    
    #关闭键
    win32api.RegCloseKey(key)
    return {"value":value}      

查询遍历注册表

import win32con,win32api

def get_software_list():
    reg_root = win32con.HKEY_LOCAL_MACHINE
    reg_flags = win32con.KEY_READ | win32con.KEY_WOW64_64KEY
    sub_key = r'SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
    soft_ware = []

    key = win32api.RegOpenKey(reg_root,sub_key,0,reg_flags)
    for j in range(0,win32api.RegQueryInfoKey(key)[0]):
        try:
            key_name = win32api.RegEnumKey(key,j)
            key_path = r'%s' % sub_key + '\\' + key_name
            path = r'%s' % key_path
            each_key = win32api.RegOpenKey(reg_root, path, 0, reg_flags)
            try:
                display_name,REG_SZ = win32api.RegQueryValueEx(each_key, 'DisplayName')
                publisher,REG_SZ = win32api.RegQueryValueEx(each_key, 'Publisher')
                #name_exe,REG_SZ= win32api.RegQueryValueEx(each_key,'UninstallString')
                if publisher == "Seewo":
                    block = False
                    seewoApp = True
                elif publisher == 'Microsoft Corporation':
                    continue
                else:
                    block = True
                    seewoApp =False
                sortware_info = {"block":block,"name":display_name,"seewoApp":seewoApp}
                soft_ware.append(sortware_info)
            except:
                continue
            print(soft_ware)
            # 关闭键
            win32api.RegCloseKey(each_key)
            

        except WindowsError:
            pass
    win32api.RegCloseKey(key)
    
    return {"soft_ware":soft_ware}      

删除注册表里某键值

import win32api,win32con

def del_RegKey(subkey_name):
    
    reg_root = win32con.HKEY_LOCAL_MACHINE
    reg_path = r"SOFTWARE\WOW6432Node\Seewo"
    
    reg_flags = win32con.WRITE_OWNER | win32con.KEY_WOW64_64KEY | win32con.KEY_ALL_ACCESS
   
    # 读取键值
    key = win32api.RegOpenKey(reg_root, reg_path, 0, reg_flags)
    win32api.RegDeleteKey(key, 'test')

    # 关闭键
    win32api.RegCloseKey(key)
    
    key = win32api.RegOpenKey(reg_root, reg_path, 0, reg_flags)
    win32api.RegCloseKey(key)      

添加注册表里键值

import win32api,win32con

def reg_add_EasiNote():
    reg_root = win32con.HKEY_LOCAL_MACHINE
    reg_path = r"SOFTWARE\WOW6432Node\Seewo\EasiNote5"
    reg_flags = win32con.WRITE_OWNER | win32con.KEY_WOW64_64KEY | win32con.KEY_ALL_ACCESS


    key,_=win32api.RegCreateKeyEx(reg_root, reg_path,reg_flags)
    # key = win32api.RegOpenKey(reg_root, reg_path, 0, reg_flags)

    win32api.RegSetValueEx(key, "type", 0, win32con.REG_SZ, '1')

    win32api.RegCloseKey(key)
