Boot Camp Control Panel " are you sure you want to reboot" after each restart

[stevetuc]

Hardware

MacBook Pro 2017 (Intel, SPI trackpad)

OS

Windows 11 Pro Version 25H2 OS build 26200.6584

Boot Camp

Boot Camp Support Software 6.1.x

Driver

DriverVer = 06/02/2021,2021.3979.1.1000

Description

After replacing the default Apple Multitouch trackpad driver with this SPI-based Windows Precision Touchpad driver, Boot Camp Control Panel enters a persistent reboot loop.

On every login, BootCamp.exe launches and prompts for a system restart to complete installation. Rebooting does not resolve the issue — the prompt reappears indefinitely.

The system is otherwise fully functional.

Expected Behavior

Boot Camp should not trigger a persistent reboot request simply because the Apple Multitouch driver has been replaced.

Actual Behavior

Reboot prompt appears on every login

Multiple reboots do not clear it

Trackpad functions correctly under Precision driver

Keyboard, startup disk, and other Boot Camp features work normally

Disabling Boot Camp from Startup prevents the prompt

Reproduction Steps

Install Windows via Boot Camp (2017 MBP)
Install official Boot Camp 6.1 drivers
Replace Apple Multitouch driver with this SPI Precision driver
Reboot
Observe persistent reboot prompt from Boot Camp

Notes / Suspected Cause

Boot Camp appears to validate the presence of AppleMultitouch.sys (or related registry/service entries) at startup. When the driver is replaced, Boot Camp flags installation as incomplete and sets a reboot-required state that never clears.

Is there a recommended compatibility approach (e.g., registry stub or dummy service entry) to prevent this validation loop while keeping Boot Camp installed?
