一、常用函数功能介绍

OpenKey() - 打开一个key

##################################################################################################################

_winreg.OpenKey(keysub_key[, res[, sam]])

  key is an already open key, or any one of the predefined HKEY_* constants.  #注册表中有六大键根,HKEY_USERS,HKEY_CURRENT_USER,HKEY_CURRENT_CONFIG,HKEY_CLASSES_ROOT,HKEY_LOCAL_MACHINE,HKEY_DYN_DATA

  sub_key is a string that identifies the sub_key to open.             #需要操作的子键

  res is a reserved integer, and must be zero. The default is zero.        #必须为0

  #sam默认为只读模式,常用有三个_winreg.KEY_ALL_ACCESS,_winreg.KEY_WRITE,_winreg.KEY_READ

  sam is an integer that specifies an access mask that describes the desired security access for the key. Default is KEY_READ. See Access Rights for other allowed values.    

##################################################################################################################
CloseKey() – 关闭一个Key

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer")
wg.CloseKey(key_test)

 

CreateKey() – 创建一个Key
DeleteKey() – 删除一个Key

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer")
wg.CreateKey(key_test,'hester')
wg.CloseKey(key_test)

 

继续创建子键

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer\hester")
wg.CreateKey(key_test,'sub_hester')
wg.CloseKey(key_test)

 

创建键值数据项

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer\hester\sub_hester")
wg.SetValueEx(key_test,'data','',wg.REG_SZ,'0') 
wg.CloseKey(key_test)

 

修改键值数据项

##################################################################################################################

_winreg.SetValueEx(keyvalue_namereservedtypevalue)

  key is an already open key, or one of the predefined HKEY_* constants.

  value_name is a string that names the subkey with which the value is associated.

  type is an integer that specifies the type of the data. See Value Types for the available types.    #类型较多不一一列举,请参考https://docs.python.org/2/library/_winreg.html#value-types

  reserved can be anything – zero is always passed to the API.

  value is a string that specifies the new value.

##################################################################################################################

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer\hester\sub_hester")
wg.SetValueEx(key_test,'data','',wg.REG_SZ,'1')
wg.CloseKey(key_test)

 

获取键值数据项值

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer\hester\sub_hester")
wg.QueryValueEx(key_test,'data')
value,type = wg.QueryValueEx(key_test,'data')

 

删除键值数据项

import _winreg as wg
key_test = wg.OpenKey(wg.HKEY_CURRENT_USER,r"Software\Microsoft\Windows\CurrentVersion\Explorer\hester\sub_hester",0,wg.KEY_WRITE)
wg.DeleteValue(key_test,'data')
wg.CloseKey(key_test)

 

输入、输出值文件

LoadKey() – 从指定文件读入键信息

SaveKey() – 保存键到文件

 

刷新注册表

FlushKey() – 回写所有的键属性改变到注册表

 

链接到其他机器的注册表

ConnectRegistry() – 链接到其他机器的注册表
