GUI

This section describes various settings in the GUI tab.

Show FPU registers as little endian

Some FPU registers, especially SSE and AVX registers, are usually used to perform parallel computation. Using little endian helps to correspond floating point numbers to their index in memory arrays. However, big endian representation are more familiar to most users. This option can set whether FPU registers are shown as little endian or as big endian. You also edit the FPU registers in the endianness set here.

Save GUI layout and column orders

Allow column order, width and layout of some views, to be saved in the config file. Note that not all views support this option. Currently, this option has not been implemented in the CPU view.

Don’t show close dialog

Do not show the close dialog when the debugger exits.

Show PID in HEX

Show PID in hexadecimal in the attach dialog. If not set, it will use decimal, just like in the Task Manager.

Enable Load/Save Tab Order

Allow x64dbg to load and save tab order. If not set, x64dbg will always use the default tab order.

Show Watch Labels in Side Bar

When you add a watched variable in the watch view, a label with the name of the watched variable can appear in the side bar of the disassembly view if the address is in the sight. They just look like labels for registers. This label might help you understand the operation and progress of a self modifying routine. If disabled, no labels will be added in the side bar for watched variables.

Do not call SetForegroundWindow

When a debug event occurs, x64dbg will focus itself so you can view the state of the debuggee. In some circumstances this might not be desired. This option can be used to tell x64dbg not to focus itself when a debug event occurs.
