Checking the sites your computer is connecting to in Windows

Have you noticed a sudden drop of your Internet speed? A possible explaination is that some nasty program is doing things behind your back. Whether it is spyware, malware or adware you might have a serious case of unauthorized traffic on your hands.

But don’t worry, it’s quite easy to get a list of your connections in Windows. Such a list may turn quite helpful and may help you find some unknown applications are using your bandwidth for their dirty bidding.

Naturally this list will be generated through the Command Prompt. First, open the Command Prompt under Administrator Mode. To do that, open the Start menu, type cmd in the search box:

Right-click on cmd.exe and select Run as administrator:

The command prompt will open:

Enter the following command:

netstat -fab 5 > connections.txt

Now, before we press Enter, let’s take a moment to look what exactly are we doing here. First of all netstat is a command that generates a lot of useful information about your network status. Additionally there are several options we can add to our netstat command, some of which are:

 -f – for displaying the full DNS name for hosts on the other side of each connection. This makes the generated data a lot easier to comprehend.

-a – to put it simply this stands for “all”. As in “all connections and listening ports”.

 -b – to output the name of the application making the connection.

Alternatively to -f you can use -n to display only IP addresses.

Naturally, “5” stands for how often do we want this information to be gathered. Finally, “> connections.txt” means that we want to output this information to connections.txt (so called piping).

So now that we now what we are doing, we can freely hit Enter.

Wait for a couple of minutes and press Ctrl + C to stop netstat. Now you can open connections.txt (which in our case is located in C:\Windows\System32  because we ran netstat from there) and see the activity of every application for the moment you started netstat, until you turned it off.

Note: This information may not be complete as we set netstat to update once in five seconds.

Note: This trick works on Windows 7 and Windows Vista. If you are still using Windows XP you need at least SP2.

How to delete a system file in Windows 7

Note: Delete system files only if you are absolutely certain what you are doing!

If you have tried to overwrite a Windows 7 system file you have probably noticed that this is not possible even in administrator mode. The reason for that is that by default the system files are owned by a service called TrustedInstaller. But of course, there is a workaround.

First open the command prompt in administrator mode. Open the Start menu, in the search box type in cmd:

How to clear the ARP cache in Windows 7

The Address Resolution Protocol (ARP) is a computer networking protocol that is used to determine a host’s MAC address using its IP. The ARP cache contains the latest IP to MAC mappings and is used to minimize ARP requests. However, sometimes the ARP cache may be responsible for slow connections and sometimes (although extremely rare) for timeouts. So, let’s learn how to flush the ARP cache.

How to hide which sites you have visited in Windows

Most of the browsers support a Private Browsing mode which allows users to surf anonymously without storing any history of the session. Although this does help you remove some of your Internet tracks it still leaves some information that can be retrieved by someone who knows a thing or two about computers. The thing is that this Private Browsing mode doesn’t delete the DNS cache. This means that, if someone types ipconfig /displaydns in the Command Prompt, he can easily find out the websites you have visited. To take care of that, we will show you how to clear you DNS cache.

First we need to run the Command Prompt in Administrator mode. To do that, open the Start menu, type cmd in the search box:

How to temporarily lock your PC after a given number of incorrect password entries in Windows 7 using the command prompt

Are you worried that your Windows 7 login password is easy to guess and that it is possible to crack it only after a few attempts? Well if you are I have two things to say to you. First, change your password. I know you have probably heard it a thousand times, but having a “smart” password is essential these days. You won’t feel comfortable if a thousand other people unlocked their front doors with a key identical to the one you use for your own front door, would you?
The second thing I have to say is, why don’t you at least lock your PC after a few incorrect entries? Surely this will make the password guessing process a lot longer.
Note: It is a good idea to have a second administrator account which you can use to unlock your PC. Just in case someone decides to do a trick on you.
Note: In case of physical access to your PC this will not slow down the use of System Rescue CD, Ultimate Boot CD or Ubuntu Live CD for resetting your password.

First, open the Command Prompt under Administrator Mode.

To do that, open the Start menu, type cmd in the search box:
