At first, some simplified introduction.
I have two laptops, one with Windows 7 and another with Windows 8.1 connected via Ethernet. I gave the first one IP 192.168.10.1 and 192.168.10.2 to the second one. This connection is shown as Unidentified network on both of them.
When I ping 192.168.10.2 from 192.168.10.1, I get Request timed out. The interesting thing is that on 192.168.10.2 in the connection status, the number of received bytes grows about the same amount (usually the same 296 bytes though it differs sometimes) as the number of sent bytes on 192.168.10.1 the moment I ping. And the number of sent bytes on 192.168.10.2 grows on 42 bytes while it's 60 for received on 192.168.10.1.
When I ping 192.168.10.1 from 192.168.10.2, I get General failure. In fact, I always get General failure regardless of what I ping, even 127.0.0.1. And in these cases, the numbers of sent and received bytes do not change.
Possibly worth noticing another thing, I'm not sure. When Default gateway is not defined, pinging address from another subnet like 192.168.1.1 gives "PING: transmit failed. General failure." unlike just "General failure" in the cases above.

Resetting TCP/IP & Flush DNS
Hosts file hasn't changed since before the laptop was bought and was working properly, so nothing interesting there.
Code:
D:\>ipconfig /release

"Access is denied", as I have found on the Internet, is about registry node
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nsi\{eb004a00-9b1a-11d4-9123-0050047759bc}\26. When I enabled Full Controll permission for this node, I got this:

Either case did not solve the problem.
I tried sfc /scannow:
Code:
Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 0% complete.
[...]
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios.
Log is attached. I couldn't find anything useful out of it but that's me.
I tried dism as well but it did not work out. Either the case is too bad or I am too lame and need assistance. I really hope it's the latter.
The firewall is disabled, the antivirus is uninstalled, safe mode with network is also affected by the problem.
Please, help me figure this thing out.
Thanks everyone of you in advance.
P.S. I have got no backups prior the begining of this problem. And reinstalling Windows is the last thing I will do.
