USB System Lock

If you're not satisfied with the securities provided by Windows perhaps you might be interested on this software called USB System Lock. This is an open source application which can be downloaded for free. The installer is very small with a size of less than 1 MB.

The installation procedure is straightforward and takes only about a couple of minutes. During the installation you will need to insert the flash drive that you are going to use to open your computer.  It then transfer the key to the flash drive. If you re-start your computer Windows is going to ask for your Windows password (as usual) and after that the USB System Lock will look for the key on the registered flash drive. If you don't have the right key it will display a message to insert the right key. You won't be able to use your computer until you insert the right key.

The way this software works is very much like the key to the door lock. You just have to be extra careful not to lose your flash drive otherwise you might end up re-installing your operating system. However, it has this feature wherein you can create a duplicate key on another flash drive. It's a good idea to have a duplicate key. Just keep it in a safe place.

How To Find Out Who's Connected To Your Computer



Would you like to know if somebody is connected to your computer? There is a dos command called "netstat" that can help you find that out.  Before you do it make sure you close your browser, email client, chat, or any software that connects to the internet.  Here's how you are going to do it:
  1. Go to run and type cmd
  2. The command prompt will open up, type "netstat -ano" (without the quotation) . You may also use "netstat -ano 10" so that it continously refresh the screen every 10 seconds.  To terminate it just press CTRL + C.
  3. Look closely for those that has "established" state.  If you see something that is connected despite that you closed already the programs that connects to the internet chances is somebody is snooping on your computer. Take note of the PID of that program.
  4. To stop that program open the Task Manager by pressing CTRL + ALT + DEL simutaneously on your keyboard.
  5. Click the "Process" tab. If you don't see there the PID you may click "View" and click "Select Columns" click on PID (Process Identifier) and click OK.
  6. Look for the PID of the program you just found from the command prompt. Click on that program and click "End Process".
Alternatively, you may use CurrPorts from Nirsoft to monitor the list of all currently opened TCP/IP and UDP ports on your computer.

Bandwidth Speed Test


 
Do you want to know the speed of your internet?  There are some websites that do bandwidth speed test such as these websites below.  One thing I like about them is they test both the download and upload speed.  Usually the other websites test only the download speed.  If your computer is connected to a network you have to make sure that the other computers are not accessing the internet except the one that you will use for testing so you can get an accurate result. 

1. www.speedtest.net
2. www.speakeasy.net
3. www.dslreports.com
4. www.bandwidth.com

By knowing the speed you can verify if you are getting the right bandwidth that you applied for from your ISP.  If the test result is close to what you applied for then there is no problem with that. However if the margin is too wide perhaps you might want to check where the problem is coming at.  Start in this sequence computer -> router -> modem -> ISP.

Remote Shutdown



 
One of the annoying practices of some employees is negligence of not shutting down their computer when they are leaving the office especially on weekend or just before holiday. If you are the one in charge of the network administration you might have encountered this once in a while. If you are “certain” that an employee has left the office already and he/she did not turn off the computer, did you know that you can remotely shut it down? You need to have an administrator priviledge so you can perform this task. I just want to warn you not to do this unless necessary because there is no way to recover unsaved documents and if windows happen to be updating at that moment might just create more trouble on the computer.

1.Click Start or Windows Logo
2.Click Run and type cmd
3.On the command prompt type shutdown /s /m \\[the name of computer] you can also use /f to force any open application to close without warning
e.g. shutdown /s /f /m \\computer10
