I'm trying to disable the popout that appears when pressing shift 5 times. Despite setting the HKCU\Control Panel\Accessibility\StickyKeys\Flags key to the 506 value in the registry, the change is not automatically applied.
I tried the code below in powershell, but to no avail:
$SKHA = Add-Type -MemberDefinition '[DllImport("user32.dll", EntryPoint = "SystemParametersInfo")] public static extern bool SystemParametersInfo(uint uiAction, uint uiParam, uint vParam, uint init);' -Name 'Test' -PassThru;
$SKHA::SystemParametersInfo(0x003B, 0, 4, 0)
The documents I used were:
SystemParametersInfoA function (winuser.h)
STICKYKEYS structure (winuser.h)
Is there any way to disable this popout without the user having to manually disable or log off/restart the system after changing the registry?
Thank you in advance.
As explained by mklement0 you need to use the STICKYKEYS structure. Here is a working snippet based on following answer which first, read the current data then apply the parameter
$MethodDefinition = @'
[StructLayout(LayoutKind.Sequential)]
public struct STICKYKEYS
{
public uint cbSize;
public int dwFlags;
}
[DllImport("user32.dll")]
public static extern int SystemParametersInfo(int uiAction, int uiParam, out STICKYKEYS pvParam, int fWinIni);
'@
$get = 0x003A
$set = 0x003B
$WinApiVariable = Add-Type -MemberDefinition $MethodDefinition -Name 'Win32' -NameSpace '' -PassThru
$startupStickyKeys = New-Object -TypeName 'Win32+STICKYKEYS'
$startupStickyKeys.cbSize = [System.Runtime.InteropServices.Marshal]::SizeOf($startupStickyKeys)
[Win32]::SystemParametersInfo($get, [System.Runtime.InteropServices.Marshal]::SizeOf($startupStickyKeys), [ref]$startupStickyKeys, 0)
Write-Host "Current:"
$startupStickyKeys.dwFlags
Write-host "Set current flag to disabled (506)"
$startupStickyKeys.dwFlags = 506
[Win32]::SystemParametersInfo($set, [System.Runtime.InteropServices.Marshal]::SizeOf($startupStickyKeys), [ref]$startupStickyKeys, 0)
