Speed Up Your Internet by 20% – Windows XP SP2 Professional

Speed up internet

Windows reserves 20% of the available bandwidth for various purposes like Windows Updates. You can get this bandwidth back by following these steps:

1. Click on Start.

2. Go to Run.

3. Type gpedit.msc and press enter key.

4. Group Policy window is opened.

5. Go to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Network -> QoS Packet Scheduler -> Limit Reservable Bandwidth.

6. Double Click on Limit Reservable Bandwidth. A Window is opened. The currently selected option  is “Not Configured”. Select Enable option. And put 0 in Bandwidth % box. Now the system will not reserve any bandwidth and the internet speed will be increased.

 

Lock Your Private Folder

Lock folder

Suppose you want to lock your private folder having name Data. This folder is at the path d:\user\data. You can lock it by using the following steps:

1. In the same drive, create a text file and type in it the following line:

ren data data.{21EC2020-3AEA-1069-A2DD-08002B30309D}

After typing this, save the file with the name loc.bat

2. Now in the same drive, create another text file and type in it the following line:

ren data.{21EC2020-3AEA-1069-A2DD-08002B30309D} data

After typing this, save the file with the name key.bat

Now two batch files loc and key will be shown. When you will double click the loc file, your data folder will be changed to control panel. And when you will double click the key folder, the changed folder will be converted back to original one.

For safety, hide the loc and key batch files by going into folder options.

 

Disk Defragmentation – Windows XP SP2

Disk Defragmentation

With time files get scattered all over the disk due to insertion and deletion. It slows down the computer since disk takes long time to access the files.

When the disk is initially empty, the first few files get copied to the disk and they are placed together one by one. When file is deleted from the disk, the remaining files do not automatically shuffle up to move into recently vacated
space. This space is left empty. When new file is copied to Hard Disk, it is told to fill up that space. If the new file can be placed into that empty space, then it will be fitted there. But if the new file is larger than the empty space, then the file is split into parts. The part that can fit into that empty space is placed there and for the remaining portion more empty space is found. As a result of this, the
files may be broken into multiple blocks, called ‘Fragments’. These fragments can be scattered all over the memory. So the computer starts taking time to access data from file and hard disk has to work harder that puts pressure on the system and life span of the system is reduced.

To overcome this problem, a technique is used. It is called ‘Defragmentation’. In it the files are rearranged so that they remain in the contiguous blocks. For defragmentation, a tool is provided by Windows and it is called ‘Disk
Defragmenter’.

Steps to run Disk Defragmenter manually in Windows XP SP2:

1. Go to My Computer.
2. Right click on a hard drive and select Properties from menu opened.
3. Select Tools tab.
4. Click on Defragment Now button.
5. Disk Defragmenter window will open.
6. Click on Analyze to check the disk for fragments.
7. A bar chart of the result will be shown below. Fragmented files are shown by red.
8. If lot of red portion is present, then click on Defragment button and wait for process to complete.
9. After the process is over, click the Close button.

Steps to run Disk Defragmenter automatically every month in
Windows XP SP2:

1. Go to Start -> All Programs -> Accessories -> System Tools -> Scheduled Tasks.
2. Double click Add Scheduled Task and click Next.
3. A list of programs will appear.
4. Click Browse. and go to C:\System30 folder and select defrag.exe.
5. Click Next.
6. Choose the schedule that is when you want to run it from the upcoming windows. Choose a time when PC is on but is likely to be idle.
7. Click Next.
8. Give the password of your system if applicable and click Next.
9. Select the ‘Open Advanced Properties…’ box and click Finish.
10. Amend the Run Box so that it reads ‘C:\Windows\System32\defrag.exe’ and click OK.
11. Now the defragmentation utility will run on its scheduled time.

System Restore On Windows XP- Bring The System Back To Safe State

System Restore

System Restore is a tool built into Windows XP. It takes regular snapshots of important system files and settings.  These snapshots are called ‘Restore Points’. Restore Point can also be created manually.

This tool can take back the system files and settings back to the point when rescue point was created and removes recently installed updates and programs to repair the problems that may have occurred. It does not touch the files and folders crested by the user. It only removes the program or application that is used to create the files and not the files created. So user data remains totally safe.

Steps for running System Restore

1. Click on Start Button.

2. Go to All Programs -> Accessories -> System Tools -> System Restore.

3. Select Restore My Computer To An Earlier Time and click Next.

4. A Calender will be displayed. Dates containing the restore points are given in bold.

5. Click on a date to see what restore points are available for that day. Each restore point’s title tells when it was taken.

6. Select the required restore point and click Next.

7. A warning will be shown. Click Next and the process begins. If it is successful, then a summary of changes will be displayed.

System Restore through Safe Mode

If the PC is unwell, then system restore can be run through Safe Mode option. For going to safe mode, restart the PC and keep pressing F8 again and again until options Menu appears. Select Safe Mode from there using arrow keys  and press enter. A Dialogue Box will appear. Click No. And use the steps given above.

Creating Restore Point Manually

1. Click on Start Button.

2. Go to All Programs -> Accessories -> System Tools -> System Restore.

3. Select Create A Restore Point and click Next.

Note:-

1. Always choose most recent restore point when the PC was working properly.

2. If a restore point gives error, then it is possible that the selected restore point has become corrupt. Select any other restore point or try Safe Mode.

Create New Keyboard Shortcut for An Application

To create a new shortcut for an application. follow the following steps:

1. An application can be assigned a keyboard shortcut. only if it appears in Start Menu. So if it is not present in Start Menu, you will have to bring it there. For this open My Computer -> C drive -> Program Files Folder. Find the required program folder, open it and drag its exe file to the Start button.

2. Right click the program icon in the Start menu.

3. Select Properties form the pop-up menu. A dialogue box will open.

4. Select Shortcut Tab.

5. Go to the Shortcut Key field.

6. Decide the combination key that will be used for your application. But this combination should be new i.e. should not be used by any other program or Window function.

7. Type the combination in the Shortcut Key field without adding Ctrl + Alt. Window will automatically add Ctrl + Alt to your decided combination. Suppose if you write 9, then it will automatically be converted to Ctrl + Alt + 9.

8. Click Ok.

9. Now whenever you will press Ctrl + Alt + 9 (in this example), the application will be opened.

Story Behind Names of World’s Best Companies

MERCEDES
This was actually the financier’s daughter’s name.

ADOBE 
This came from name of the river Adobe Creek that ran behind the house of founder John Warnock.

APPLE COMPUTERS 
It was the favorite fruit of founder Steve Jobs. He was three months late in filing a name for the business, and he threatened to call his company Apple Computers if the other colleagues didn’t suggest a better name by 5 O’clock
that evening.

CISCO
It is not an acronym as popularly believed. It is short for San Francisco .

COMPAQ
This name was formed by using COMp, for computer, and PAQ to denote a small integral object.

COREL 
The name was derived from the founder’s name Dr. Michael Cowpland. It stands for COwpland REsearchLaboratory.

GOOGLE 
The name started as a joke boasting about the amount of information the search-engine would be able to search.  It was originally named ‘Googol’, a word for the number represented by 1 followed by 100 zeros. After founders- Stanford graduate students Sergey Brin and Larry Page presented their project to an angel investor, they received a cheque made out to ‘Google’ …thus the name.

HOTMAIL
Founder Jack Smith got the idea of accessing e-mail via the web from a computer anywhere in the world. When Sabeer Bhatia came up with the business plan for the mail service, he tried all kinds of names ending in ‘mail’ and finally settled for hotmail as it included the letters “html” – the
programming language used to write web pages. It was initially referred to as HoTMaiL with selective upper casing.

HEWLETT PACKARD
Bill Hewlett and Dave Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett.

INTEL
Bob Noyce and Gordon Moore wanted to name their new company ‘ Moore Noyce’but that was already trademarked by a hotel chain so they had to settle for an acronym of INTegrated ELectronics.

LOTUE (Notes)
Mitch Kapor got the name for his company from ‘The Lotus Position’ or ‘Padmasana’. Kapoor used to be a teacher of Transcendental
Meditation of Maharishi Mahesh Yogi.

Founder Paul Galvin came up with this name when his company started manufacturing radios for cars. The popular radio company at the time was called Victrola.

ORACLE
Larry Ellison and Bob Oats were working on a consulting project for the CIA (Central Intelligence Agency). The code name for the project was called Oracle (the CIA saw this as the system to give answers to all questions or something such). The project was designed to help use the newly written SQL code by IBM. The project eventually was terminated but Larry and Bob decided to finish what they started and bring it to the world.They kept the name Oracle and created the RDBMS engine. Later they kept the same name for the
company.

SONY
It originated from the Latin word ‘sonus’ meaning sound, and ‘sonny’ a slang used by Americans to refer to a bright youngster.

SUN
Founded by four Stanford University buddies. SUN is the acronym for Stanford University Network. Andreas Bechtolsheim built a microcomputer;
Vinod Khosla recruited him and Scott McNealy to manufacture computers based on it, and Bill Joy to develop a UNIX-based OS for the computer.

YAHOO!
The word was invented by Jonathan Swift and used in his book ‘Gulliver’s Travels’. It represents a person who is repulsive in appearance and action and is barely human. Yahoo! Founders Jerry Yang and David Filo selected the name because they considered themselves yahoos.

Nameless Folder

To create nameless folder, the steps are:

1. Create a folder and select it.

2. Press F2 to rename it.

3. Turn on the numeric keypad if it is off, since the trick works only with the numeric key pad and not with normal numeric keys.

6. After typing, press enter.

7. Nameless folder is created.

Drag and Drop to the Command Line in DOS

MS DOS

In case of DOS, when you work with the files having a long file path, then instead of typing the full path just drag-and-drop a file into the command line.

For example:

If you want to copy college.jpg file from D:\Ritiks\pics\random\new\clicks directory, then open that folder in Windows Explorer and drag and drop the file into the command line. And “D:\Ritiks\pics\random\new\clicks\college.jpg” will be entered into the command line.

Red Eye Effect

Red Eye Effect

It is a photographic effect in which a flash reflects from the back of the subject’s retinas which give the eyes a red glow. The effect can be reduced with red-eye reduction pre-flash that comes before the photo is taken. Many cameras have a built-in red-eye reduction pre-flash that helps to reduce the effect of red eye. Red-eye reduction works by having the flash shine a light into the eyes of the subject prior to taking the picture. This causes the pupil to contract and reduces the reflection.

File Compression

It works on the basis of concept of data redundancy.  Most types of computer files are fairly redundant. They have the same information written over and over again. File-compression programs simply get rid of the redundancy. Instead of listing a piece of information over and over again, a file-compression program lists that information once and then refers back to it whenever it appears in the original program.

For example we have following sentence:

“Ask not what your country can do for you — ask what you can do for your country.”The sentence has 17 words, made up of 61 letters, 16 spaces, one dash and one period. If each letter, space or punctuation mark takes up one unit in memory, the total file size will be of 79 units. To get the file size down, we need to look for redundancies.

We notice that:

  • “ask” appears two times
  • “what” appears two times
  • “your” appears two times
  • “country” appears two times
  • “can” appears two times
  • “do” appears two times
  • “for” appears two times
  • “you” appears two times

Ignoring the difference between capital and lower-case letters, roughly half of the phrase is redundant. Nine words — ask, not, what, your, country, can, do, for, you — give us almost everything we need for the entire quote. To construct the second half of the phrase, we just point to the words in the first half and fill in the spaces and punctuation.

To compress we pick out the words that are repeated and put them into the numbered index. Then, we simply write the number instead of writing out the whole word.

So, if this is our dictionary:

 

  • ask
  • what
  • your
  • country
  • can
  • do
  • for
  • you

 

Our sentence now reads:

 

“1 not 2 3 4 5 6 7 8 — 1 2 8 5 6 7 3 4”

 
If you knew the system, you could easily reconstruct the original phrase using only this dictionary and number pattern. This is what the expansion program on your computer does when it expands a compressed file.

But how much space have we actually saved with this system? “1 not 2 3 4 5 6 7 8 — 1 2 8 5 6 7 3 4” is certainly shorter than “Ask not what your country can do for you; ask what you can do for your country;” but keep in mind that we need to save the dictionary itself along with the file.
