# SetWinDelay

Sets the delay that will occur after each windowing command, such as WinActivate.

    SetWinDelay, Delay

## Parameters

Delay

  Time in milliseconds, which can be an expression. Use -1 for no delay at all and 0 for the smallest possible delay. If unset, the default delay is 100.

## Remarks

A short delay (sleep) is done automatically after every windowing command except WinActive() / IfWinActive and WinExist() / IfWinExist. This is done to improve the reliability of scripts because a window sometimes needs a period of "rest" after being created, activated, minimized, etc. so that it has a chance to update itself and respond to the next command that the script may attempt to send to it.

Although a delay of -1 (no delay at all) is allowed, it is recommended that at least 0 be used, to increase confidence that the script will run correctly even when the CPU is under load.

A delay of 0 internally executes a Sleep(0), which yields the remainder of the script's timeslice to any other process that may need it. If there is none, Sleep(0) will not sleep at all.

If the CPU is slow or under load, or if window animation is enabled, higher delay values may be needed.

The built-in variable A_WinDelay contains the current setting.

Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this command. That default may be changed by using this command in the auto-execute section (top part of the script).
