Hello folks,

revisiting, obviously still present. Refining the summary a bit to also include
creation part.

Standard path patterns for kernel services in well-known locations:

* '\SystemRoot\system32\drivers\foobar.sys'
* 'system32\drivers\foobar.sys'
* 'foobar.sys' (SCM automatically prepends '\SystemRoot\system32\drivers')

Private paths:

* '\??\C:\Program Files (x86)\MyProduct\foobar.sys'

Also encountered with SmartGaga (Android Emulator) v1.1.x from bug 48933

'NtCreateFile' needs to see an NT-style path here, hence the error.

Wine's SCM created the kernel service registry data with "normal" private path
which obviously can't work for drivers retrieving the 'ImagePath' value at
runtime.
