How to clean up the Add or Remove Programs tool utility in Control Panel

When uninstalling a program, you normally click on the Remove button on the Add or Remove Programs tool utility. It will ask you for confirmation to uninstall the program and once the program has been uninstalled, the program name entry will be removed from the list. However, when the Remove button does not work, and the program stays on the list (instead of asking for the confirmation), you can remove the entry from the list by deleting the registry entry on the Registry Editor. Extreme care should be taken when working on registry entries.

How to remove the program entry on the Add/Remove Programs tool:
1. Click Start -> Run.
2. Type regedit.
3. Click OK. The Registry Editor will open.
4. Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.
5. Find the key you want to delete (example: Mozilla Firefox 12 x86).
6. Save a backup of the registry key: On the Registry Menu, Export the registry key. Import this key later if necessary.
7. Delete the selected registry key and its values. WARNING!! Do not delete the entire Uninstall key.
8. Close the Registry Editor.
9. Check to make sure the program entry has been removed: Click Start.
10. Control Panel -> Add or Remove Programs.

How to Secure your Computer Network

What is a computer network?
A network is a system of interconnected computers which can communicate, share resources and transfer data. The Internet is an example of a computer network.

We have seen and experienced the tremendous advantages and benefits of computer networks, but as the computer technology advanced so are the crimes in the  computer industry. Identity theft, unauthorized access, illicit downloads, scams, computer viruses, spywares, adwares, malwares, trojans, worms, hijackers, trackwares, dataminers...the list goes on, these are just few of the bad things that we want to stay away from. There can be no such thing as completely secure network, but with useful knowledge and with the help of security tools, the risks and dangers can be minimized. Below is a list of practical and basic means of safeguarding your network as well as yourself.

Top 10 ways of securing your network:


When you purchased those wireless routers, they are mostly designed so that it is easy to setup and install, but the problem is that security features are being compromised and disabled. To provide security to your wireless network, follow these steps:

- Change the default password of your wireless router

- Change the name (SSID) of your wireless router

- Disable SSID broadcast on your wireless router

- Enable WEP or WPA encryption on your wireless router and on your wireless network adapters


Once your password is stolen or cracked, your personal information will be taken and your accounts will be in danger. To secure your passwords, follow these steps:

- Don't make obvious and easy to guess passwords, instead use a combination of characters, numbers, capital letters, and signs

- Choose a different password for each of your accounts

- Keep your passwords secret, and if you wrote it down, store it in a safe place

- Change your passwords on a regular basis
 or when you feel it is being known by someone else

- Never use the "Remember password" option, your laptop computer may be stolen and your files can be easily accessed


A computer virus may corrupt valuable files or even delete files and directories, trigger a computer crash, or even shutdown an entire operating system, and other harmful and unpredictable damages. To protect your network:

- Make sure an effective antivirus is installed on every computer on the network

- Enable active, resident, or real-time protection

- Schedule regular automatic virus scans

- Configure the Antivirus program to automatically receive updates (virus signatures)


Spywares are malicious programs intended to gather information (spy) from your computer. Adwares are annoying programs that popup advertisements (usually banner ads) to promote another site and thereby increase traffic. To get rid of all these kinds of troubles on your network,

- Install antispyware, anti-adware and popup blocker on every computer on the network

- Enable active, resident, or real-time protection

- Schedule regular automatic spyware and adware scans

- Setup the Antispyware, Adware blocker and Popup blocker programs to automatically receive updates


Broadband, high-speed connections which are always on are perfect targets for hackers, thieves, and frauds. Firewalls are used to prevent these cheaters from obtaining access to your network. To ensure protection, make sure to setup and install a firewall on each computer on the network, then, periodically check the firewall rules to give access only to the programs allowed and trusted by you.


Even when your computer is lost or stolen, encryption software can provide a further protection of sensitive data and information. If the file is encrypted, it can not be readily read by thieves and attackers, thus delaying their dirty work and giving you extra time to do the necessary actions.


Talk to your children about the dangers that the Internet poses. Warn them not to give out addresses, birthdays, names, and other private information. Review the website history to determine the places your kids went into. To minimize the online risks, allow your children to only use the computer when you or any responsible adult can monitor and watch them.


Phishing is a method of identity theft designed by scam artists that is implemented by sending emails to unsuspecting victims in order to trick them to provide their personal data such as passwords, credit card numbers, bank account numbers, and other personal and financial information. The usual tactic is to tell to the victim of the urgency that their account is about to expire or be soon suspended. A link is then provided for the victim to click which then leads to fake website (but authentic-looking) then the victim is lured to provide sensitive information. To avoid being a victim of phishing emails:

- Real banks and financial institutions don't request confidential financial information via email, don't ever open or read these emails

- Don't click on any links within the phishing email

- Never reply or send any emails asking you for private personal information on your account


Ponzi scheme (named after Charles Ponzi) is a deceptive investment strategy which promises quick and high returns in order to entice new investors. Payments to investors actually come from new investors' money and never from the fraudulent company.

Multilevel Pyramid scheme is a fraudulent business in which a prospective investor is ask to make one payment and then to recruit a new investor who would also make a payment. The first investor is offered a sum of money as a result of his recruit. The new recruit then recruits other people and the process of recruiting goes on and the more downlines, the more profits being promised.


Backups are important data recovery and network security method. If a virus or other malicious software or program corrupted all the files on the network, you have something to go back to. The significance of backing up your files is also realized when problems arise such as accidental file or folder deletion, hard drive malfunction or failure resulting in data loss, stolen computers and drives, fires, floods, earthquakes and other damages.

How to remove the hard drive from a dead laptop?

What if your screen is broken by impact or your laptop fall down to the concrete floor. Your monitor may be broken, or dim, or dark, or shattered but there is big possibility that the data and information, your files, folders and documents may still be intact in your hard drive...This article will discuss the instructions that are easy to follow in order to remove the hard drive from your laptop.

Turning an old hard drive into an external storage device

One of the cons of a laptop is when the screen gets damaged or is too dim and dark that you can not see anything. That is what happened to my wife's laptop. The screen had a built-in camera that she used for webcam while on chat and video calling. She also used the laptop to watch streaming videos that made the video card worked so hard. One time, after a long day of chatting and video calling, it was shut down like the usual way but when she started up her laptop on the following morning with the intent of checking her email...POOF!....the screen is totally dark, but the startup sound is still heard with the hard drive light still colored green and the sound of success can still be heard if the password is entered correctly. There were three options that came to my mind to remedy this problem.

First, is to replace the display screen but then the parts and labor is too expensive. Second, is to buy a monitor and plug it to the laptop using a monitor cable and connect it to the display port on the side. This seems to be a reasonable choice but then I will need some space and plus the awkwardness of a black dead screen beside a monitor. Third, is to remove the hard drive and buy a 2.5 inch Serial ATA (SATA) to USB 2.0 HDD enclosure and turn the hard drive as a portable storage device while keeping the original files, folders, media, data, music, photos, videos, and other essentials intact and accessible. The best choice for me turned out to be the third one.

Below I will discuss the step by step procedure of how to remove the hard drive from a dead laptop or one with a dark screen. These instructions are supported with illustrated photos and pictures to understand better for the reader:

1. Disconnect the adapter from the power source.

2. Remove the battery from the laptop.

3. Touch a metal surface to get rid of the static charge in your hands.

4. Turn up the bottom side of the laptop.

5. The hard drive is located inside a lid with an almost square shape. Loosen and remove the two screws.

6. Pull out the cover.

7. Pull out the plastic at the end of the hard drive.

8. Carefully pull the hard drive out, paying attention not to damage the sensitive pin area and connectors.

9. After removing the hard drive from the laptop, handle it with care and carefully place it in a safe, clean, no moisture, no sunlight, no magnetism, no vibration, in an area with no high or low temperatures, while it is not yet inserted and installed in an appropriate hard drive enclosure.

10. Insert and Install the laptop hard drive in a 2.5 inch hard drive enclosure.

Once your mobile phone is unlocked, it will work with any SIM card. Mobile phone manufacturers include a feature called SIM lock or network lock. This locking feature is used by mobile network providers or carriers to limit your phone's usability to a specific country and mobile network signal providers. This would mean that they can take advantage of offers and contracts so that they will recover their promotional offers (cheap phones or free phones) in exchange of you signing to a contract of usually 3 years and you can select among option based on your preferences, each option with different monthly bill. If your phone is locked, then it would prevent you from breaking the original contract. They lock your phone for safety in case you sign a new contract with a new mobile network provider while being actively under a contract. To avoid contracts and be on the safe side, choose "Pay as you go" or Pre-paid or other similar options. The first important question to take into consideration is:

What is considered illegal?

Unblocking a mobile phone or device is illegal. This is usually in the case where a phone was lost or stolen and was reported by the owner of the phone and consequently blocked by the carrier networks. Unblocking is when you make the phone to work again by crafty means even if it is being actively blocked. Don't attempt to do this. Severe penalty will result.

Nokia phones are one of the easiest to unlock because of the many websites providing the lists of unlock codes for free. Yes, no charge. You can also get unlock codes by calling a company or internet site for a small fee. Other options are paid services - you pay and they give you your unlock codes or you can bring your phone and they will unlock your phone for you.

How to enable port forwarding on your router

A port is a way by which your computer communicate with the internet. Example, an application such as an online game will use the port for incoming or outgoing flow of information. The Hypertext Transfer Protocol (HTTP) is the means by which our computer communicates with other computers in the world and port 80 is the default port of communication. By default, the port number for a web server is port 80. 

What is port forwarding?

Port Forwarding will tell the router which computer on your home network to send the data to. Routers assign port numbers to a Service that is associated with a specific Application on your computer. Below is the step by step procedure of how to open ports on your router and how to configure port forwarding.

How to enable port forwarding on your router: (based on a D-Link router)

1. Open a web browser (Internet Explorer or Mozilla Firefox).

2. Type the URL address of the router in your browser. This is usually

3. Enter the router's username and password. The default username is "admin". For the password, it generally works by leaving it blank and just pressing Enter.

4. Click on Advanced -> Virtual Server.

5. Check the Enabled button.

6. Give a name for your new virtual server. Example "John Home Web Server".

Shortcut keys for Windows, Windows Explorer, Word, Internet Explorer, Firefox, & Google Chrome

If you can do something fast and you know how to do it faster, why not do it? Yes, the mouse is fine and the touchpad is doing great but sometimes your fingers get stressed by using them over and over again for continuous period of time that you want to get rest and relax. By knowing keyboard shortcuts, there is an alternate way of achieving the same results and often faster and reliable. It buys you some time to relax the finger muscles you have been using and use another finger or group of muscles and bones, therefore a balance is achieved, giving you comfort and relieving some stress.

For some people, keyboard shortcuts are very convenient and they do work faster, save time, and do more. Anyways, my objective is to provide help to people who wants to know and learn some helpful keyboard shortcut keys for their benefit and convenience.

Byte: a basic unit of data storage capacity in consumer electronics, devices, and products

Ever wondered what is MB, GB, TB on your cellphones, Ipods, MP4s, Iphones, Ipads, Blackberry phones, laptops, handhelds, USB pen drives, digital cameras, videocams, camcorders, desktop computers, hard drives, PlayStations, PS2, PS3, Xbox, Xbox 360, Wii, PSP, and so on... in those electronic devices, products , gadgets, and gizmos?

A byte is a unit of data storage capacity. The size of a byte depends on the hardware used for a certain device or product. One byte is used to represent or store one character and is  generally equivalent to 8 bits. One bit (binary digit) can only have one value of either 0 or 1.

A character (letter, number, punctuation mark, etc.) like 'c' or '5' or '/' or '?' or space is equal to 1 byte.

A useful rule of thumb is One Thousand characters equals 1 KB.

The Binary Table:

1 byte = 8 bits = 1 character

1 Kilobyte (KB) = 1024 bytes

1 Megabyte (MB) = 1024 KB

1 Gigabyte (GB) = 1024 MB

1 Terabyte (TB) = 1024 GB

1 Petabyte (PB) = 1024 TB

1 Exabyte (EB) = 1024 PB

What is AIRPLAY?

AirPlay is a technology developed by Apple company that is used to wirelessly stream media such as pictures, music, and video. Airplay is used mainly between Apple devices such as iPad, iPhone, iPod, and iPod Touch but the audio streaming of some non-Apple devices also uses Airplay. Although Airplay works on the traditional wired Ethernet connection, the main goal of Airplay is for wireless streaming (via Wi-Fi) of media so that it is available to any room in the house at any time. When you use AirPlay-enabled speakers with graphical displays, the AirPlay wireless technology also streams the information about your music such as the title of the song, the artist, the name of the album, and other related information directly to your speaker's display.


Bluetooth is an open (to all manufacturers, not only Apple) wireless technology that is used to transfer data or stream media like audio, photos, and contact information from one Bluetooth enabled device to another. Bluetooth was originally designed for portable equipment and mobile devices. Without the need of a Wifi network, Bluetooth is a wireless networking technology that uses low-frequency signals to transmit and receive. Main uses and applications of Bluetooth are with smartphones, tablet computers, notebook, laptop, desktop computers, Blu-ray players, AV receivers, home theater systems, wireless printing, hands-free calling, headsets with Bluetooth, Car deck, In-Dash Car Video Deck, GPS receivers, and many more.

Key advantages of Bluetooth:

- Bluetooth works without a Wi-Fi network
- provides better and flexible compatibility between devices and operating systems
- good audio quality
- simplicity of setup and installation
- reasonable range of 30 feet or 10 meters
- reasonably affordable prices
- no more messy wires to connect

Difference between Bluetooth compatible and Bluetooth-enabled

Bluetooth Compatible or sometimes called "Bluetooth ready" means that the device supports Bluetooth wireless technology and uses an external (via USB) Bluetooth adapter or dongle. Bluetooth Enabled or "built-in Bluetooth" means the device has a Bluetooth adapter already built-in within the inside of the device and does not need an external USB adapter or USB dongle.

What is WI-FI?

Wi-fi networking uses a wireless router to connect wifi devices such as computers, printers, smartphones, blu-ray players, modern TVs (HDTV, plasma TV, LED TV, 3D TV, Smart TV), video game consoles, digital audio players, and other Wi-Fi ready and Wifi-enabled or Wifi built-in devices. These wifi devices can be setup in their Wi-Fi settings to enable them to connect to the wi-fi router access point or hotspot. A wireless router allows connection to the Internet and is usually effective to within 100 feet (30 meters) range. Wi-fi is used in wireless local area networks (WLAN). Wi-Fi is the wireless replacement alternative to the traditional wired Ethernet network which uses Ethernet cables. Using Wi-fi, a smartphone does not need the cell phone provider's 2G, 3G, or 4G networks to send and receive email text messages, voice messages, photos and pictures, audio and music files, videos, and other file transfer services.

WiFi Ready vs. WiFi Built-in

Wi-Fi ready means the device supports wireless Wi-Fi connection but no wifi adapter is integrated to the device. An external adapter has to be purchased separately and has to be plugged in to the device using the USB port. Wi-Fi built-in means that the device already has an adapter or a transmitter/receiver that is installed inside the device. Both Wi-Fi ready and Wifi built-in devices are capable of streaming contents from the internet or from the home network devices and servers.

Popular and major uses of Wi-Fi:

- connecting bluray players, home theatre systems, TVs, computers to the home wi-fi network
- wirelessly transfer, send, share, stream media files, movies, music, videos, photos
- stream audio to any speaker, anywhere, any time within your home, house, or small office
- sync or wireless synchronization of music, photo, video, movie libraries and other files (no more wires to connect and no more plugging of the device to the USB port)
- wireless printing of documents
- using wi-fi, a smartphone can be used as a modem (tethering) for connecting your laptop computer to the internet
- using wifi, a smartphone can be used as a remote control
- many more applications...

How to clean Laptop fan

How to clean laptop computer cooling fan?
Do you hear that annoying sound of your laptop computer's fan when it is running fast, hard, and noisy especially when you are playing online videos such as youtube videos or when playing video games? Does your laptop touchpad, keys, and keyboard heat up? Does the bottom or underneath of your laptop is abnormally hot and noisy? If the answer to any or all of these questions is yes, chances are that your laptop computer cooling fan and air suction, exhaust, and passage grill or screen are dirty. Below I will describe clearly and logically in an easy and simple to follow instructions the step by step procedure how to carefully and safely clean your laptop cooling system.

How to clean laptop computer cooling fan and cooling system:

1. Shutdown and turn the power off your laptop. Remove the charger chord and the battery.

2. Close the lid (screen) of your laptop.

3. Turn your laptop upside down so that the bottom part is now facing you.

4. With an appropriate screwdriver, loosen the screw of the cover where your cooling fan is located.

How to setup & configure a fast, secure, organized and efficient home network

Setting up a computer network depends on a number of requirements such as speed, security, efficiency, cost, application, etc. A business computer network may have several workstations, file servers, mail servers, print servers, VPN servers, DHCP servers, Hubs, Bridges, Switches, Routers, etc. An efficient network is one in which speed is achieved while maintaining a reasonably high level of network security in a cost-effective pricing of network component hardwares and softwares.

A seemingly complicated business enterprise model network may have lots of interconnected devices but it is built upon a simple basic configuration.

The setup and configuration below is based on a home network of 5 components:
1. D-LINK DI-524 (802.11g/2.4GHz Wireless Router) --------------------> Gateway

2. Dell Desktop (Microsoft Windows XP Home Edition Service Pack 2) ---> File Server

3. Asus Laptop (Microsoft Windows XP Home Edition Service Pack 2) ----> Mobile PC

4. Toshiba Laptop (Microsoft Windows Vista Home Premium) -------------> Mobile PC

5. Cables (Ethernet, Coaxial) ----------------------------------------> Connectors & for Data Transfer

In the simple basic home network above, the following are achieved:


* broadcasting of SSID is disabled (with the wireless setting for the Access Point SSID Broadcast set to "Disabled", a nearby neighbour is prevented from discovering your network)

* WPA-PSK Security setting (new models of routers have WPA2 security type and AES encryption type which are the latest technology for wireless security)

* strong hard-to-guess, carefully chosen passwords are essential for better secured networks

* DHCP IP Addresses are limited to two (knowing beforehand that there are only two laptop computers and setting the Starting and Ending IP addresses so that the router is only allowed to supply 2 IP Addressess, thereby lessening the probability of access from potential sniffers to your wireless home network)


* Speed is achieved because the router doesn't have to choose dynamically from 100 IP Addresses (under DHCP Server, the D-Link Router has by default Starting IP Address and the Ending IP Address, by controlling these limits, it can only be restricted to give access to two client computers)

* Mobility is achieved by setting the two laptops with Dynamic (DHCP) IP Addresses instead of Static IP Addresses [for a network administrator in a business enterprise network, setting the mobile laptops with DHCP IP Addresses instead of Static IP Addresses has the advantage of easy management and maintenance while offering the flexibility of the laptop users to access a different subnet within the business network and thereby minimizing downtime for administrator setup in case the users move from one department to another department]

* Efficiency and Organization is achieved by setting the File Server with a Static IP Address so that its address is fixed, readily available to everyone on the network to be easily accessed
