I sent a message some time ago (I think between 6 months and a year ago) to the 
list with what has to be done to enable ShrewSoft VPN in the newer windows 10s. 

Please look at the list history for my mail as my notes on this are archived I 
don't know where...

Actually, I found my notes on this:

From http://www.ruudborst.nl/shrewsoft-vpn-filter-blocks-traffic-on-windows-10/

Shrew Soft VPN filter blocks traffic on Windows 10

Because of management reasons we have to use Cisco VPN Client or ShrewSoft for 
VPN connections. Since I upgraded to Windows 10 I also needed a VPN to our 
management servers. Both vendors have an outdated installer and apparently not 
compatible with Windows 10 Technical Preview 2 (TP2) so I ended up with a 
connectivity problem.
The Cisco VPN client wouldn’t install, to overcome this issue you have to set 
the following reg key, restart your PC and install it again.

    sp 'HKLM:\System\CurrentControlSet\Control\Network' -Name MaxNumFilters 
-Value 14 -Type DWORD

ShrewSoft VPN client installs, but after it is finished the network connection 
is lost. The adapter is still enabled but no packets are sent or received. This 
is because of the network client filter Shrew Soft installed. Somehow, (because 
of security/DNE corruption reasons?) a legacy scripted install won’t allow the 
filter to be correctly installed on Windows 10. The solution is to uninstall 
the filter and install the filter manually like the screenshot below.
When you still have no network connection after a reboot then run winfix.exe 
from Citrix, reboot again and then apply dneupdate64.msi. The winfix utility 
cleans up most Windows operating systems to enable installation of products 
that use DNE (VPN) and other products like DNE. The dneupdate installer 
installs the newest DNE filter which works with the Shrew Soft filter and 
solves the issue entirely.  More information can be found on their page 

Hope this helps and still works.

Subject: [vpn-help] Windows 10 issues

We are having a lot of problems with windows 10 and software not working 
correctly with various security updates from Microsoft.  Classic to windows 10.
Currently my VPN tunnel won’t enable on my windows 10 machine but it works on 
all other machines running on windows 7.
Has anyone else had this problem?  Any ideas on how to work around this? 
Thanks Marty
