保存一些代码为 reg.py，运行之即可。

#/usr/bin/env python
# -*- coding: utf-8 -*-
 
import sys 
     
from _winreg import * 
     
# tweak as necessary 
version = sys.version[:3] 
installpath = sys.prefix 
     
regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version) 
installkey = "InstallPath" 
pythonkey = "PythonPath" 
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % ( 
    installpath, installpath, installpath 
) 
     
def RegisterPy(): 
    try: 
        reg = OpenKey(HKEY_CURRENT_USER, regpath) 
    except EnvironmentError as e: 
        try: 
            reg = CreateKey(HKEY_CURRENT_USER, regpath) 
            SetValue(reg, installkey, REG_SZ, installpath) 
            SetValue(reg, pythonkey, REG_SZ, pythonpath) 
            CloseKey(reg) 
        except: 
            print "*** Unable to register!" 
            return 
        print "--- Python", version, "is now registered!" 
        return 
    if (QueryValue(reg, installkey) == installpath and 
        QueryValue(reg, pythonkey) == pythonpath): 
        CloseKey(reg) 
        print "=== Python", version, "is already registered!" 
        return 
    CloseKey(reg) 
    print "*** Unable to register!" 
    print "*** You probably have another Python installation!" 
       
if __name__ == "__main__": 
    RegisterPy()  

 

完。
