Python之注册表增删改查（干货）

在Windows平台下，对注册表的增删改查的需求比较多，微软提供了很多用于访问，修改注册表等的API，我们可以使用诸如bat，或者C++等各种方式去访问修改注册表。无所不能的python下如何完成这些操作呢？pywin32模块中提供了与微软提供的C++等语言API一致的使用python对注册表进行操作的接口。今天带给大家的是对注册表进行修改的代码（PS:想使用的孩纸直接复制拿走，亲测可用！）需要的孩纸们直接看代码：

import win32api, win32con
import sys

__author__ = 'Berlin'

def ModifyReg(key, keyPath, valueName, valueType, value):
    try:
        '''
        RegConnectRegistry: 
            computerName: string(If None, the local computer is used)
            key: int(May be win32con.HKEY_LOCAL_MACHINE...)
        '''
        keyHandle = win32api.RegConnectRegistry(None, key)
        '''
        RegOpenKeyEx:
            key: PyHKEY/int
            subKey: string
            reserved = 0: int(Reserved. Must be zero.)
            sam = KEY_READ: int(If you want to set the value later, you must open the key with KEY_SET_VALUE)
        '''
        subkeyHandle = win32api.RegOpenKeyEx(keyHandle, keyPath)
        '''
        RegQueryValueEx:
            key: PyHKEY/int
            valueName: The name of the value to query
        '''
        (currValue, type) = win32api.RegQueryValueEx(subkeyHandle, valueName)
        if (currValue == value):
            print 'PASS: Check reg value: %s' % valueName
            return 1
        else:
            print 'INFO: The %s is not the same as %s' % (valueName, value)
            print 'INFO: Try to set %s as %s' %(valueName, value)
            subkeyHandle = win32api.RegOpenKeyEx(keyHandle, keyPath, 0, win32con.KEY_SET_VALUE)
            '''
            RegSetValueEx:
                key: PyHKEY/int
                valueName: string(The name of the value to set)
                reserved: any(Zero will always be passed to the API function)
                type: int(REG_DWORD, REG_SZ ...)
                value: registry data
            '''
            win32api.RegSetValueEx(subkeyHandle, valueName, 0, valueType, value)
    except:
        print 'FAIL: ModifyReg %s. Exception happened. Exception happened when accessing registry key under %s.' % (valueName, keyPath) 
        return 0
    print 'SUCCESS: ModifyReg %s value under %s' % (valueName, keyPath)
    return 1

def main():
    key = win32con.HKEY_LOCAL_MACHINE
    AUPath = r'SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update'
    valueName = r'AUOptions'
    valueType = win32con.REG_DWORD
    value = 1
    ModifyReg(key, AUPath, valueName, valueType, value)
    
if __name__ == '__main__':
    sys.exit(main())

实例是修改Windows自动更新的注册表项，将其修改为1.
