This guide provides optimization steps for Windows Precision Touchpads (PTP), primarily based on official Microsoft documentation and practical testing.

OEM Optimization:

This section contains settings extracted from native Precision Touchpad configurations.

To apply these settings, create a new text file, rename it to elan.reg, and import it into your Registry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PrecisionTouchPad]
"AAPDisabled"=dword:00000000
"HorizontalOffset"=dword:0000012f
"RightClickZoneHeight"=dword:00000000
"RightClickZoneWidth"=dword:00000000
"SpaceBarOffset"=dword:000003e8
"RightClickZoneCorrected"=dword:00000001
"AAPNonCurtainTop"=dword:0000085c
"AAPNonCurtainBaseWidth"=dword:00000dd2
"HorizontalOffsetIsNeg"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PrecisionTouchPad\IgnoredExternalMice]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PrecisionTouchPad\LegacyControlled]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PrecisionTouchPad\LegacyDevices]

After importing, navigate to the following path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\PrecisionTouchPad

Restart your computer to apply the changes.

Expanding the Physical Right-Click Zone:

If you find the physical right-click area too small, you can adjust it manually.

Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\PrecisionTouchPad

Adjust the following values:

  • RightClickZoneHeight: Set to 64 (Hexadecimal value, which equals 100 in Decimal. This represents 100% of the touchpad height).
  • RightClickZoneWidth: Set to 32 (Hexadecimal value, which equals 50 in Decimal. This represents 50% of the width, covering the right half of the touchpad).

Restart your computer to apply the changes.

The values in these registry settings are based on a 0–100 decimal scale, representing percentages:

  • RightClickZoneHeight: a percentage of the height of the entire touchpad measured from the bottom edge.
  • RightClickZoneWidth: a percentage of the width, measured from the right edge in right-handed,
    and the left edge in left-handed configurations when the swap mouse buttons option is enabled.

You can customize these two values according to your personal preference.
