I’m trying to programmatically enable/disable the option:

Settings → Bluetooth & devices → Touchpad → Taps → "Tap with a single finger to single-click"

When toggled manually through Windows Settings, the effect is immediate.

However, when I modify the corresponding registry keys under:

HKCU\Software\Microsoft\Windows\CurrentVersion\PrecisionTouchPad

the change is only applied after a full system reboot.

I have already tried:

• Restarting Explorer (explorer.exe)

• Restarting input-related services (e.g. hidserv, TabletInputService)

• Re-enumerating devices (pnputil /scan-devices)

• Restarting drivers (HID / touchpad)

• Killing and reopening SystemSettings.exe

None of these approaches apply the change immediately.

Is there a way to:

1. Force Windows to reload Precision Touchpad settings without rebooting, or

2. Simulate the toggle action programmatically (e.g., via API, PowerShell, or UI automation) so the effect is applied instantly?
