Steps to install Windows 8 from USB Drive

  

 With the release of the Windows 8 Developer Preview, my curiosity could not let me wait and I rushed to install it right then. But not having an optical drive on my netbook could hinder my installation and hence I had to come up with this alternative of installing it via a pen drive. And to my surprise, when I tried to make a Windows 8 bootable pen drive using the  Microsoft’s very own Windows 7 USB/DVD Download Tool.

System Requirements for Windows 8 are:

·         1 Gigahertz or faster 32-bit or 64-bit processor

·         1 Gigabyte of RAM for 32-bit, 2 Gigabytes of RAM for 64-bit minimum

·         16 Gigabyte hard drive for 32-bit systems, 20 Gigabyte for 64-bit systems

·         Direct X 9 graphics card

The prerequisits for the installation are as follows:

• Firstly, you need to download the Microsoft Windows 8 Developer Preview Image from  here
• Next, you need to have with your self the  Windows 7 USB/DVD Download Tool, which can be downloaded from here.
• You need an USB pen drive with at least four Gigabytes of free space. 

With both the softwares downloaded we are now ready to make our own bootable pen drive with Windows 8. Though it does require few tweaks other than making the pen drive bootable, you can follow the steps as given below:

Formating the Pen Drive

• Firstly, we need to format the pen drive to the FAT32 file system. This can be done by connecting the pen drive to the computer, right-clicking its drive icon and selecting Format from the drop down menu. The Format window pops up where you need to make sure that Fat32 is the selected file system. Other details need not be changed.
• Once this is done, open the Windows 7 USB/DVD Download Tool.
• Then just select the Windows 8 ISO when asked to pick an ISO image from the computer.
• Next, select to copy the contents to an USB drive. The program will copy all files to the drive and make that drive bootable at the same time.
•  Once this is done, restart your PC, get into the BIOS by pressing F8/F12 as per your manufacturer and goto the Boot Configuration section and enable the USB Booting as well as make USB Booting primary in the booting preference.
• Save the settings and exit the BIOS.
• On restart, the computer should now automatically boot through the pen drive and begin the installation.

 

 

Windows Vs Linux A Brief Comparison

Windows and Linux are both operating systems that have been developed to allow the utilization of computer resources . These two systems have a number of differences and require different things from users for proper operation of the system. Among the major differences is that  


"Windows is a commercial operating system, while Linux is an open source operating system."
                       
                                 Windows is the widest used PC operating system today. It’s graphical user interface allows users with no programming experience or knowledge to navigate the system and complete the tasks. Some users have experienced stability problems, but with typical individual use the system has proven to be stable enough to prevent a massive shift. Windows OS has different versions that are tailored for various needs. 
  
Linux is an open source operating system. It is renowned among users as being far more stable than the Windows system. Some network administrators and programmers prefer the system, but for a number of reasons the system has not gained the level of market penetration that Windows or MacOS have reached. Little support by software makers has been among the problems. Though, with some knowledge, it is possible to run most Windows versions of programs on Linux systems. Also, while the system offers a graphical interface, there remains a bit of coding involved in the implementation of some programs. This can prove difficult for some users.

• Price: The majority of Linux variants are available for free or at a much lower price than Microsoft Windows.
  Microsoft Windows can run between $50.00 - $150.00 US dollars per each license copy.
• Ease: Although the majority Linux variants have improved dramatically in ease of use, Windows is still much easier to use for new computer users.     Microsoft has made several advancements and changes that have made it a much easier to use operating system, and although arguably it may not be the easiest operating system, it is still Easier than Linux.
• Reliability: The majority of Linux variants and versions are notoriously reliable and can often run for months and years without needing to be rebooted.Although Microsoft Windows has made great improvements in reliability over the last few versions of Windows, it still cannot match the reliability of Linux.
• Software: Linux has a large variety of available software programs, utilities, and games. However, Windows has a much larger selection of available software. Because of the large amount of Microsoft Windows users, there is a much larger selection of available software programs, utilities, and games for Windows.
• Software Cost: Many of the available software programs, utilities, and games available on Linux are freeware or open source. Even such complex programs such as Gimp, OpenOffice, StarOffice, and wine are available for free or at a low cost.    
  Although Windows does have software  programs, utilities, and games for free, the majority of the programs will cost anywhere between $20.00 - $200.00+ US dollars per copy.
• Hardware: Linux companies and hardware  manufacturers have made great advancements in hardware support for Linux and today Linux will support most hardware devices. However, many companies still do not offer drivers or support for their hardware in Linux.    
  Because of the amount of Microsoft Windows users and the broader driver support, Windows has a much larger support for hardware devices and a good majority of hardware manufacturers will support their products in Microsoft Windows.
• Security: Linux is and has always been a very secure operating system. Although it still can be attacked when compared to Windows, it much more secure.Although Microsoft has made great improvements over the years with security on their operating system, their operating system continues to be the most vulnerable to viruses and other attacks.
• Open Source: Many of the Linux variants and many Linux programs are open source and enable users to customize or modify the code however they wish to.Microsoft Windows is not open source and the majority of Windows programs are not open source.
• Support: Although it may be more difficult to find users familiar with all Linux variants, there are vast amounts of available online documentation and help, available books, and support available for Linux.Microsoft Windows includes its own help section, has vast amount of available online documentation and help, as well as books on each of the versions of Windows.

        

What is a computer virus?

A computer virus is a small software program that spreads from one computer to another computer and that interferes with computer operation. A computer virus may corrupt or delete data on a computer, use an e-mail program to spread the virus to other computers, or even delete everything on the hard disk.

Computer viruses are most easily spread by attachments in e-mail messages or by instant messaging messages. Therefore, you must never open an e-mail attachment unless you know who sent the message or unless you are expecting the e-mail attachment. Computer viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread by using downloads on the Internet. Computer viruses can be hidden in pirated software or in other files or programs that you may download. 

Symptoms of a computer virus

 

If you suspect or confirm that your computer is infected with a computer virus, obtain the current antivirus software. The following are some primary indicators that a computer may be infected:

• The computer runs slower than usual.
• The computer stops responding, or it locks up frequently.
• The computer crashes, and then it restarts every few minutes.
• The computer restarts on its own. Additionally, the computer does not run as usual.
• Applications on the computer do not work correctly.
• Disks or disk drives are inaccessible.
• You cannot print items correctly.
• You see unusual error messages.
• You see distorted menus and dialog boxes.
• There is a double extension on an attachment that you recently opened, such as a .jpg, .vbs, .gif, or .exe. extension.
• An antivirus program is disabled for no reason. Additionally, the antivirus program cannot be restarted.
• An antivirus program cannot be installed on the computer, or the antivirus program will not run.
• New icons appear on the desktop that you did not put there, or the icons are not associated with any recently installed programs.
• Strange sounds or music plays from the speakers unexpectedly.
• A program disappears from the computer even though you did not intentionally remove the program.

Note These are common signs of infection. However, these signs may also be caused by hardware or software problems that have nothing to do with a computer virus. Unless you run the Microsoft Malicious Software Removal Tool, and then you install industry-standard, up-to-date antivirus software on your computer, you cannot be certain whether a computer is infected with a computer virus or not.

What is Spyware?

  Spyware can install on your computer without your knowledge. These programs can change your computer’s configuration or collect advertising data and personal information. Spyware can track internet searching habits and possibly redirect web site activity.

Symptoms of Spyware

When a computer becomes affected by Spyware, the following may result:

• Slow internet connection.
• Changing your web browser’s home page.
• Loss of internet connectivity.
• Failure to open some programs, including security software.
• Unable to visit specific websites, which may include redirecting you to another one.

How to remove a computer virus and spyware.

 

Even for an expert, removing a computer virus or spyware can be a difficult task without the help of computer malicious software removal tools. Some computer viruses and other unwanted softwarereinstall themselves after the viruses and spyware have been detected and removed. Fortunately, by updating the computer and by using malicious software removal tools, you can help permanently remove unwanted software.

 
To remove a computer virus and other malicious software, follow these steps:

Install the latest updates from Microsoft Update:

1. For Windows Vista and Windows 7:
   1. Click the Pearl (Start) button, then type Windows Update in the search box.
   2. In the results area, click Windows Update.
   3. Click Check for Updates.
   4. Follow the instructions to download and install the latest Windows Updates.
2. For Windows XP:
   1. Click Start, then click Run.
   2. Type sysdm.cpl and press the Enter key.
   3. Click the Automatic Updates tab and choose the Automatic (recommended) option.
   4. Click OK.           
    
3. Rogue security software programs will try to make you think that your machine is infected by a virus and usually prompt you to download and/or buy a removal product. The names of these products usually contain words like “Antivirus,” “Shield,” “Security,” Protection,” “Fixer,” so they appear to be legitimate. They will often run immediately when downloaded, or the next time your computer starts up. Rogue security software can prevent applications from opening, including Internet Explorer, and may display legitimate and very important Windows files as infections. Some typical error messages or pop ups you may receive may contain:
   
   Warning!
   Your computer is infected!
   This computer is infected by spyware and adware.
    

How To Lock Your PC Automatically

Would you like your computer to automatically lock and require you to enter your password when you exit the screen saver?  Here’s how to quickly change your screen saver settings to keep your computer secure when you’re away.

To get started, right-click on your desktop, and click Personalize to open the personalization settings dialog.

Click Screen Saver under the themes to change your screensaver settings.

Alternately, if you’d rather open the screensaver settings without grabbing your mouse, hit the Win key and enter Screen Saver in the search box, and select Change screen saver.

This will open the Screen Saver settings dialog.  Select the screensaver you want, then check the box to display the login screen when you exit the screen saver.  Enter the number of minutes you want to wait before your screensaver starts, then click Ok to save your settings.

Now, after the length of time you selected, you’ll see your screensaver as normal.

Then, when you move the mouse or press a key, you’ll see the normal login screen instead of your desktop.  Enter your password and login as normal to access your computer.

Lock Your Computer Without a Screensaver

If you’re not fond of screensavers, you can lock your computer when you’re away without turning on the screensaver.  Just select None from the screensaver list, then check the box as before.  Now your computer will automatically switch to the Login screen whenever your computer is left for the amount of time you selected.

This trick only works if your coworkers and family doesn’t know your password, of course.
