Attempts to do an in-place upgrade on a XPS 13 9350 Windows 8.1 to Windows 10 resulted in lockups around 71%. The issue appears to be the WiFi driver or more specifically BCM.sys. If this driver is removed before the Windows 10 upgrade: the upgrade goes flawlessly.
First step is to get a copy of the Windows Development Kit or WDK from Microsoft to obtain the devcon executable.
Next, go into the device manager and get the VEN/DEV id:
Now we remove it!
devcon /r remove "PCI\VEN_8086&DEV_7110"
Now proceed on with the rest of your task sequence.
