How to change Windows Console Font to Consolas

If you're trying to figure out how to change the Windows console font to another one, this post will help you.

Run:
chcp 65001
Then you should be able to change it now.
If you add Python to the ENV path, you can start python directly from the console. But python may complain: "unknown encoding: cp65001"
To fix that:
Add PYTHONIOENCODING=utf-8 as a new ENV variable 

Another dumbest thing of windows console is that: the shortcut of cmd.exe won't get saved in the regedit. But if you run cmd.exe directly, the font settings will be saved in the regedit. So If your changes don't stick, you should run cmd.exe directly instead of running the cmd command, which is just a shortcut of cmd.exe. STUPID Windows console!!

How do I put my hotkeys and hotstrings into effect automatically every time I start my PC?

There are several ways to make a script (or any program) launch automatically every time you start your PC. The easiest is to place a shortcut to the script in the Startup folder:

    Find the script file, select it, and press Ctrl+C.
    Press Win+R to open the Run dialog, then enter shell:startup and click OK or Enter. This will open the Startup folder for the current user. To instead open the folder for all users, enter shell:common startup (however, in that case you must be an administrator to proceed).
    Right click inside the window, and click "Paste Shortcut". The shortcut to the script should now be in the Startup folder.

Chinese Input Method: 输入法：搜狗输入法去广告版，在baidu网盘中。Windows 10/11 bug: Ctrl + Space is always the default Chinese IME/Non IME switch, need to fix by following: Change both HKEY_USERS\.DEFAULT\Control Panel\Input Method\Hot Keys and  HKEY_CURRENT_USER\Control Panel\Input Method\Hot Keys (You can copy and paste the path to the address bar) Change 00000010 | Key Modifiers to 02 c0 ..., which is Ctrl, and Virtual Key to bc 00 00 00, which is comma. (http://www.kbdedit.com/manual/low_level_vk_list.html)

This way, you'll change to use ctrl + , as the language IME/Non IME switch: use Sougou as the default input method with English as the default. If the system reverts the change, modify HKEY_CURRENT_USER\Control Panel\Input Method\Hot Keys again. To prevent the change reversion, change the permission of the key 00000010  as the following pic:
