I found that a lot of what forum friends share is through cmd Go to start Multiple wechat
Although it can realize more opening , But not flexible enough , For example, I logged in to a wechat this morning , It's not easy to login in the afternoon
It could be me, of course start The posture is not right . So I searched the single instance principle , I have realized a ready to use and open . At present, many software restrict single instance , Most software uses Mutex To achieve
And this thing we can use handle Go and kill it , And does not affect the use of .
Nailing is the same procedure however Mutex Their names are different
The nail I tested was ：

”\Sessions\1\BaseNamedObjects\{ {239B7D43-86D5-4E5C-ADE6-CEC42155B475}}DingTalk“

Dry goods mainly include ：

① 200 Multiple copies Python e-book （ And classic books ） Should have

② Python Standard library information （ The most complete Chinese version ）

③ Project source code （ Forty or fifty interesting and reliable hand training projects and source code ）

④ Python Basic introduction 、 Reptiles 、 Network development 、 Big data analysis video （ Suitable for Xiaobai to learn ）

⑤ Python Learning Roadmap （ Farewell to bad learning ）

Here we need to use two Microsoft software Namely ：procexp handle
Next, start the text ：
First of all, let's judge manually Mutex Which is .
That's what we need procexp.exe 了 Run the program as an administrator .
Select wechat process Press Ctrl+L The bottom half of the picture will appear .

In the software, we can find type yes Mutant Of Then right click to close Try one by one I've tried here, so I won't demonstrate Directly to everyone

name
\Sessions\1\BaseNamedObjects\WeChat_GlobalConfig_Multi_Process_Mutex

After this step The mission of this tool is completed ！ Next use handle 了
stay cmd Enter the following code

handle -a -u -p 12668 "\Sessions\1\BaseNamedObjects\WeChat_GlobalConfig_Multi_Process_Mutex"

Then we can close the handle

handle -p 12668 -c 460 -y

Be careful ： This code requires administrator privileges
Then we can open wechat .
Now let's use python To realize
Code may be different from analysis because

"\Sessions\1\BaseNamedObjects\WeChat_GlobalConfig_Multi_Process_Mutex"

Medium 1 Sometimes it turns into other numbers , So I used the matching rule
Combine the code with handle.exe Put it in a directory

import os
import re
import psutil
def get_pid(name):
"""
Get all wechat processes
"""
process_list = psutil.pids()
pids = []
for pid in process_list:
if psutil.Process(pid).name() == name:
pids.append(pid)
return pids
def more_open(path):
pids = get_pid("WeChat.exe")
for pid in pids:
# Traverse all wechat pid hold Mutex Get rid of it
cmd = f"handle -a -u -p {pid}"
with os.popen(cmd) as f:
result = f.read()
search_result = ""
for i in result.split("\n"):
if i.strip():
if i.strip().endswith("_WeChat_App_Instance_Identity_Mutex_Name"):
search_result += i
if not search_result:
os.startfile(path)
continue
re_result = re.findall('(\d+): Mutant', search_result, re.S)
# The loop above is a match Mutex Of handle
if re_result:
for _id in re_result:
os.system(f'handle -p {pid} -c {_id} -y')
os.startfile(path)
path = "D:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
more_open(path)
