Default Registry entry

My ISP provides internet Over LAN & uses "Cyberoam 24online" client To authenticate to the Server. Check the link for detail

I have to keep logged in with this Client to use internet.. Now the Problem Part:-
when u use this client Software, it kind of exhibits Firewall behaviour & Blocks all the Popular Ports(7,80,21,137,139) on the Perticular ethernet Interface. u cant even ping the Machine. but still i managed to run FTP using the Port 2121. BUT recently 3 days back my isp upgraded the Software & now the Problem is that the bandwidth of all inbound & outbound TCP connections from the Lan card do not Cross more than 128 kbps. Now this is pathetic as i suffer alot on my home LAN. Even if i have to copy something from my PC to Laptop -- it will only Download/upload with the 128 kbps(be it Any port) which used to be over 5mbps earlier
there is a Registry setting which bounds the Bandwidth of a Certain ethernet NIC.

The Client makes some Specific entries in the Registry Key
HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesTcpip Parameters
which Thus Disables the TcpIP Ping & File sharing Ports & also restricts the Bandwidth from a Specific Adapter.
I attach the REG file for Study

when I deleted the & Rebooted mymachine Once -- the Pinging & File sharing Etc. were back in Action-- which Confirms that the Client is using some Registry Based Tweak only. Moreover --after deleting the keys when i tried running the Client it Stopped saying "Client Tampered- - components Missing Reinstall Client"

now what i wanted is that if somehow its possible Patch the EXE & make it work Without the KEYS -- my Purpose is Solved

If anybody intrested i can send him the exe thorugh mail it of 400 kb
So just plz reply
