open regedit and browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\DPS\Parameters
Post output

Same for key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SstpSvc\Parameters
Same for key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WfpLwf

There is no Parameters key in DPS and SstpSvc.
This is what is in the DPS key:

Thx for the reg files.
The Sstp service starts up without any error.
Although the DPS key looks correct now I still get the same error when I start up this service.
And in the Event log is still see the message: "The following boot-start or system-start driver(s) failed to load:
WfpLwf".
If I open the Device Mgr I see under Non-Plug and Play Drivers an exclamation mark at WFP-Lightweight Filter.
Device Status:"This device is not present, is not working properly, or does not have all its drivers installed. (Code 24)".

I see on other forums that there ate many people with problems with WAN mini-ports and VPN. And till now there is not any solution.

In the attachment the CBS-Log file. It's created after I merged the reg files!

-The Diagnostic Policy Service service terminated with the following error:
The system cannot find the file specified.

Still that error message?
C:\windows\system32\dps.dll is on system?

Yes it's there. version 6.1.7601.17514
