Where is emacs's init file located?

You have to create it.

and emacs looks for specific directory for it.

By default, emacs looks at the following directories.

On Windows 10, Windows 8, Windows 7, Windows Vista:

The init file may be byte-compiled, ending in “.elc”. If a .emacs.elc or .emacs.d\init.elc file exist, emacs will load those instead.

If you have the environment variable named “HOME”, then it's at:

“HOME” should not be confused with “HOMEPATH”.

(info "(emacs) Find Init")

How to start emacs?

To run emacs inside Windows Console, start like this:

Create a Windows shortcut, then set the “Start in” field.

GNU emacs shortcut properties, in Windows 7.

To create a file shortcut:

  1. Hold Alt then drag that runemacs.exe icon to desktop.
  2. In the newly created alias icon, right click to open file properties. Then, in the “Start in” field, enter %home%.
  3. In the “Target” field, you can add your own init files. For example, here's mine: %home%\apps\emacs-24.1\bin\runemacs.exe -q --load=%home%\ErgoEmacs_dev\init.el --load=%home%\.emacs. Here, i suppress loading init files by -q, but load ErgoEmacs init files, then load my personal init files.

When i type Ctrl+Space, Windows switches me to other language input. What to do?

You can disable the Windows shortcut that switches you among input methods of different languages.

On Microsoft Windows 10:

  1. go to Control Panel
  2. Under icon “Clock, Language, and Region”, click link “change input methods”
  3. Click “Advanced settings” on the left panel.
  4. Change language bar hot keys.

Here's the exact instruction for Windows Vista.

  1. Go to 〖Start ▸ Control Panel〗.
  2. Choose Classic View on the left.
  3. Double click on the “Regional and Language Options” icon, then go to “Keyboards and Languages” tab, click on “Change Keyboards…”.
  4. Then, go to “Advanced Key Settings” tab, then, it should list Key sequences on the right column.
  5. Select a input choice that has shortcut key, then click the button “Change Key Sequence”.

When i type 【Ctrl+Alt+s】, HP System info came up. How to disable that?

See: Disable Ctrl+Alt+S of HP Support Information.

How to run Bash shell or PowerShell inside emacs?

By default, the command named shell will run “cmd.exe” inside emacs.

You can use eshell.

〔►see Emacs: M-x eshell

For powershell, install the powershell package. 〔►see Emacs: How to Install Packages Using ELPA, MELPA

Where to get language modes for Visual Basic, “cmd.exe”, PowerShell?

Search MELPA. See Emacs: How to Install Packages Using ELPA, MELPA.

There are several packages for cmd.exe batch file, written by different people. You may want to try them in the order listed here:

Environment Variables

Two environment variable important to emacs are HOME and PATH.

Note: by default Windows 7 and Windows Vista, Windows 10, they have HOMEPATH, but not HOME.

HOMEPATH is Microsoft Windows's environment variable. HOME is unix's. Both are meant to be the full path of home directory.

Setting Your Home Dir

You should set a HOME env var. Here's how you do it in cmd.exe:

REM example of setting HOME env var
setx HOME "C:\Users\jane"

If you are running emacs within Cygwin, then the init file will be at ~/.

See: Windows Environment Variables Basic Tutorial.

Setting Environment Variable for Emacs Only

See: Emacs: Set Environment Variables within Emacs.

Using Cygwin

Some of emacs's features require unix utilities. For example, spell checking requires “aspell”, image thumbnail preview requires ImageMagick, checking difference between files require diff, listing files with particular suffix requires unix find (used by find-dired).

If you came from a unix background, you may want to install unix shell and utilities such as {“diff”, “find”, “grep”, …}. I recommend Cygwin.
