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?
