1.0, on the computer, open more WeChat

Generally, if we use a computer, we can only open one WeChat. Clicking again will only open the WeChat that has already been opened.
Below, I will teach you how to open multiple WeChat accounts on one computer.

1. On the computer desktop, right click and create new text. Rename - "Open more WeChat" (you can choose this name at will, as long as you know it yourself)
2, Find the WeChat shortcut. Right-click properties – copy the path of the "target" location inside.
look at the picture below
3. Paste the copied path into the "WeChat multi-open" text we just used, and add start in front. **Then put the position of the first quote after the first slash "".
as follows,

//start 你的微信目标位置路径，正常是这样
"D:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
我们需要改成，下面这样
D:"\Program Files (x86)\Tencent\WeChat\WeChat.exe"
然后，在前面添加 start

最终就是这样
start D:"\Program Files (x86)\Tencent\WeChat\WeChat.exe"

In this way, we can open a WeChat. Since it is multi-open, let’s copy a few more

//最终，我们复制了3份
start D:"\Program Files (x86)\Tencent\WeChat\WeChat.exe"
start D:"\Program Files (x86)\Tencent\WeChat\WeChat.exe"
start D:"\Program Files (x86)\Tencent\WeChat\WeChat.exe"

Finally, as shown below

4 Finally, we changed the suffix of the "WeChat multi-open" text to bat. Then, double-click to try it (remember to log out of WeChat first)

to run the effect. In this way, you can open multiple WeChat accounts and chat with yourself. . .
