Yea that is odd because I haven't had any lock ups either. Other than everyonce in a while it will lock up for a second or 2 but it comes right back. This is again only while doing something cpu intensive or bringing up a webpage with lots of animated ads. What are you doing when it locks up? What is your time delay in the microsoft device settings?
Delay Settings -
Change PC Settings(just like to turn off the driver signing) > PC and Devices > Mouse and Touchpad > Touchpad I have mine set to "No delay always on". Then I turned my smartsense back on to the lowest setting so that when I type the touch pad stops working until I stop typing again.
I can tell you that there is a driver that gets updated during the process and it isn't only the software. I have no idea what it is that gets updated though. Following the steps I gave, before going into safe mode and copying the 64bit folder, if you open the old software it opens and gives you an error. The error is that the driver version and the software version do not match. You click ok and the software does open, but the profiles don't work correctly. In it you still see that the driver version is the new updated version. By copying and pasting the software it updates it so that it works but then we just get the evaluation errors.
I have tried forcing the drivers on the specific mouse hardware in device manager but it does not work. Once it went through but the touchpad failed to function. A second time it caused me to blue screen and have to reboot.
