Add Information and Image in My Computer

When you open properties of My computer, what all information do you see? Most common things are OS details under System, Registered to "Your name", and Processor and Ram details under Computer.

What if you want to add more information? Yes, more information can be added to the My Computer properties. How?
Well I must tell you it is very very easy to do this, and believe me this is as simple as Cut Copy Paste
Here is what you need to do

  1. Open Notepad, and type in the following.
  2. [General]
    Manufacturer="You can type any information here"
    Model="You can type any information here"

    [Support Information]
    Line1="You can type any information here"
    Line2="You can type any information here"

    1. P.S. - All the characters are case sensitive
    2. You can add upto 10 lines in the Support Information section
    3. Name this file as "OEMINFO.INI", and place it in System32 Folder
    4. Just refresh and open My Computer Properties, and you will see additional information

    To add an Image, follow these steps

    1. Create any image of 125 X 125 pixel
    2. Save it by name of "OEMLOGO.BMP"
    3. Place this file in System32 folder
    4. Refresh and you are done

    If in case you want to undo these changes, just delete these files from system32 folder, and you will be back to normal.

Editing The Boot.ini File

Boot.ini file is an initialization file, but editing it for some people has been a bad experience. In this post i will let you know the codes and their meaning and also how to edit them easily. By default this is hidden in Xp, but in case of win 98, it can be searched.
To access the file in Xp :-

  • Right click on My Computer and select Properties.
  • Go to the Advanced tab and click Settings in Startup and Recovery section.
  • Click Edit and you will see the Boot.ini file opened in a notepad.

Now File says something like this

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

The First line [Boot loader] just states the Booting Process.
timeout=30 is the time that will be provided to you to select from the list of OS's installed. This works only in case you have multiple OS's installed. It can be reduced easily, but make sure you give enough time to react upon it. 10 Seconds is the appropriate time.
The third line says multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect. multi(0) tells us the IDE on which the drive is attached to. Usually its Primary only. disk(0) shows the number of Hard disks mounted. rdisk(0) tells us from which disk it is booting. In case of SCSI drives, it might not show up. partition(1) tell that on which Logical partition the OS is installed on.
After that it says "Microsoft Windows XP Professional" that is the name that shows up on the OS selection page. You can put your own name there as well.
This was the editable part of Boot.ini file.
Now in case if you delete the file accidentally then you need not worry, you don't need to create the file again. Xp will create a file of its own, and your system is safe.
But in case if someone edits it and puts in the wrong information, then it you system will find the file but not the correct path. So that might harm your Computer.

Hope everyone got some idea abt editing boot.ini...

Boot XP from an External device

Many of u mite have faced a problem of missing Boot.ini file. The computer was not able to boot because it was not able to find the proper location of the boot files, thus creating a problem. But for this simple reason, you cannot format your computer, and when you know its just a small file. What can then be done?
Usually when this file is deleted, it automatically rewrites a new file, and this booting the system. But in this case, it was not. Whats the solution then ?

Well, to this problem what can be done is booting XP from a external device, be it Floppy, Pen drive or even a Disk. You just need to copy the booting files into these devices, and all is then controlled by XP.
You need to have a second computer, in case your computer is down too. But if it is healthy and doing good, prepare a copy NOW !!!
Boot XP
Firstly format your device like Floppy, or Pen drive in a FAT File system, and then copy "ntldr" and "ntdetect.com" files from the i386 folder of XP disk. Then you need to copy your Boot.ini file to the drive to make it bootable.
That's it You can then boot your computer from any external device.

Restore Your Computers Performance

If you think that your computer is not giving that kind of performance that it was giving about six months or a year back when it was new, then might your systems performance has degraded. This does happens with due course of time, with the softwares being installed and un-installed from the computer.
If you are using Windows Xp then this OS does contain some tools that might help you restoring your computers performance. I will be telling you know about these tools.

Just before trying all, do take Backup of your data. At least for the Root directory.

  • Remove Unused Programs : Now this is the most common tip that must be followed to make a good start. As soon as you decide that you wont be using that software anymore, go ahead and uninstall it from Control Panel –> Add/Remove Programs. These softwares when unused remains in your computer and lowers its performance. You might need to restart your computer in some cases, do restart and follow the same if you have any other unused programs.
  • Run Disk Cleanup : Removing unused files like Temporary Internet Files, Recycle Bin and other files with the help of Disk cleanup. You can access it by going into My computer –> Local Drive Properties –> Disk Cleanup. Click this button and it will analyze your computer and show you that which all files can be deleted and how much space can be taken out from it. Click on OK and your files will be removed by the tool. You must run this cleanup at least once in a Month. Also If you are having multiple drives, do perform the same operation on others.
  • Defragment Your Drives : Lets first see that what is fragmented files and Defragmented files.
    Fragmented files would be the one which we can say as scattered. As these files are saved and edited from time to time therefore they get saved onto different sectors of Hard Drive. This makes computer more time to search for it and show the correct page.
    This image will make things more clear.
    Disk Defragmentation

    Disk Defragmenter collects all the similar files and take them to a single place or sector in a drive, this makes computer in finding the files more easily and more Quickly.
    Disk Defragmentation
    You can run this tool once in six months, also depending on your usage. You can access this tool by going onto Start –> Programs –> Accessories –> System Tools –> Disk Defragmenter.

  • Remove Unused Network Connections : If you have ever made a network with one or more than one computers then you must have realized that it is really easy to share data. Now the problem is that when Windows boots, it patiently waits for the other computer to respond on the network, if not then it keeps on waiting, making you irate, untill it gets a proper answer from the other computer or till the time outs. This makes the system really slow specially during Boot process. Now to disable that, Right click on "My network places" and click "Disconnect Network Drive", it will show you all the drive to disconnect and you can choose from there, which are of no use.
  • Remove Startup Items : When computer Boots, you would be able to see the some icons in the System Tray, these might look to you as shortcuts but they are like Burden on your computer as computer has to start each of these application and thus making it slower. These Startup items can be removed by a called "msconfig". Go to Run –> type msconfig and click Startup tab. In that tab click "Disable all" and the Restart you computer. Now this will make the booting of your computer real fast.
These were some of the tips to restore your computers performance levels. Do try them at your computer and see the difference.

Difference between http:// and https:// - U should Know

The main difference between http:// and https:// is
It's all about keeping you secure

HTTP stands for HyperText Transport Protocol, which is just a fancy way of
saying it's a protocol (a language, in a manner of speaking) for information to
be passed back and forth between web servers and clients.

The important thing is the letter S which makes the difference between HTTP and HTTPS.

The S (big surprise) stands for "Secure".

If you visit a website or webpage, and look at the address in the web browser, it will likely begin with the following: http://.

This means that the website is talking to your browser using the regular
'unsecure' language.

In other words, it is possible for someone to "eavesdrop" on your
computer's conversation with the website.

If you fill out a form on the website, someone might see the information you
send to that site.

This is why you never ever enter your credit card number in an http
website!

But if the web address begins with https://, that basically means your computer is talking to the website in a secure code that no one can eavesdrop on.

You understand why this is so important, right?

If a website ever asks you to enter your credit card information, you should
automatically look to see if the web address begins with https://.

If it doesn't, there's no way you're going to enter sensitive information like a
credit card number!
