View | Options

Click Options on the View menu to open the Options dialog box. This command is equivalent to clicking the button (Screen shot of the Options button) on the toolbar.

Dialog Box

In the Options dialog box, you can select or deselect the following options:

Tab width

The Tab width box controls how tab characters are displayed in any Source window. In the Tab width box, enter the number of spaces that you want to have between each tab setting. (The default setting is 8. For more information about text properties, see Changing Text Properties.)

Reuse after opening this many

The Reuse after opening this many box controls the number of document, or source, windows that can be open at the same time. If the specified number of source windows has been reached, opening a new window causes an existing window to close. Windows that are marked as tab-dock targets do not close. The last windows to close are the ones you used most recently.

Parse source languages

If the Parse source languages check box is selected, the text of source code in all Source windows is colored according to a simple parse of the source syntax. To change the colors, in the Colors area of the dialog box, select a syntax element and then click Change. (To turn the syntax colors off in a single Source window, open that window's shortcut menu, click Select source language, and then click <None>.)

Evaluate on hover

If the Evaluate on hover check box is selected (and the Parse source languages check box is selected as well), symbols in a Source window will be evaluated when you select that window and then hover over a symbol with the mouse. The evaluation is the same as that produced by the dt (Display Type) command.

Enter repeats last command

If the Enter repeats last command check box is selected, you can press the ENTER key at an empty prompt in the Debugger Command window to repeat the previous command. If you clear this check box, the ENTER key generates a new prompt.

Automatically scroll

The Automatically scroll check box controls the automatic scrolling that occurs when new text is sent to the Debugger Command window. If you want to turn off this feature, clear the Automatically scroll check box. For more information about this scrolling, see Using Debugger Commands.

Workspace Prompts

In the Workspace Prompts area, you can click one of three options to determine when and how frequently the workspace is saved in WinDbg.

  • If you click Always ask, when a workspace changes (such as when a debugging session ends), the debugger displays the Workspace save dialog box where you can save the workspace.

    In the Workspace save dialog box, if you click Don't ask again, WinDbg resets the Workspace Prompts option to Never save or Always save.

  • If you click Always save, the workspace is saved automatically whenever it changes.

  • If you click Never save, the workspace is not saved when it changes, and you are not prompted to save it.

QuickEdit Mode

If the QuickEdit Mode check box is selected, you can right-click an item to copy or paste, depending on the window selection state. When you clear this check, QuickEdit is disabled and you can right-click an item to open a shortcut menu for the window. You cannot give individual windows different settings; the QuickEdit setting applies globally to all windows. By default, this box is selected. The QuickEdit setting is saved in the current workspace.


To change the color of the source text that is displayed, select an item from the Colors area and then click Change. Select a color, or select a custom color, and then click OK.

In the Colors menu, you can change the colors of the following items:

  • The first ten items represent text in the Disassembly window and the Source window.

  • The Changed data text item represents data entries that have been changed (for example, in the Registers window).

  • The ten Source Xxx items control the colors that are used for syntax elements in the Source window.

  • The remaining items refer to different kinds of text in the Debugger Command window.

These color changes take effect when you click OK. To discard these changes, click Cancel.
