准备

本实例需要使用WMI模块，所以需要安装WMI模块。在安装WMI模块之前，先要安装pywin32模块，WMI模块需要win32api的支持。使用pip安装pywin32模块和WMI模块的代码如下：
pip install win32com
pip install wmi

代码

import wmi
import random
import os
sec="t95p0q2f6dz1cxmowgjensr7yh384bvualki"
dec="dn7vhlk3wx1efsyc56zu2bomjtq8i0g4rp9a"
c = wmi.WMI()
for physical_disk in c.Win32_DiskDrive():hard_seral=physical_disk.SerialNumber   # 获取硬盘序列号print("硬盘序列号为：",hard_seral)
if len(hard_seral)>6:hard_seral=hard_seral[-6:]
else:print("硬盘信息获取错误！")os.exit(0)
for cpu in c.Win32_Processor():cpu_seral=cpu.ProcessorId.strip()     # 获取CPU序列号print("CPU序列号为：",cpu_seral)    
if len(cpu_seral)>4:cpu_seral=cpu_seral[-4:]
else:print("CPU信息获取错误！")os.exit(0)
for board_id in c.Win32_BaseBoard():board_id=board_id.SerialNumber        # 获取主板序列号print("主板序列号为：",board_id)    
if len(board_id)>6:board_id=board_id[-5:]
else:print("主板信息获取错误！")os.exit(0)    
seral=hard_seral+cpu_seral+board_id
print("注册码使用的硬件信息为：",seral)  
cha_seral=""
for i in range(0,14,2):cha_seral+=seral[14-i]+seral[i+1]     # 字符串尾和首递进连接生成新的字符串
cha_seral=cha_seral+ seral[7]             # 字符串的中间值放到新字符串最后   
list_seral=list(cha_seral)                # 字符串转为列表 
list_seral.reverse()                      # 列表反转
rand_seral=""
for i in range(10):                      # 将前10个字符串和其位置索引（16进制）连接j=random.randint(1,len(list_seral))rand_seral+=hex(j)[2:]+list_seral[j-1]   # hex(j)[2:] ，去掉16进制前的符号0xlist_seral.remove(list_seral[j-1])
rand_seral=''.join(list_seral) +rand_seral   # 形成25位的字符串
low_seral=""
rand_seral=rand_seral.lower()
for item in rand_seral:j=sec.index(item)low_seral+=dec[j]
low_seral=low_seral.upper()    
last_seral=low_seral[0:5]+"-"+low_seral[5:10]+"-"+low_seral[10:15]+"-"+low_seral[15:20]+"-"+low_seral[20:25]
print("生成的注册码为：\n",last_seral)
