Backup Registry Before Too Late
All Windows stores its configuration information in a database called the registry. The registry is the central storage for all computer configuration data.
Although the registry appears to be in one file, it is actually placed on your computer in several files. Depending on your system configuration, registry files can be found in any of the following locations:
C:\Documents and Settings\User Name\ on Windows 2000, XP.
C:\Windows\System32\Config\ on Windows 2000, XP.
C:\Windows\ on Windows 95, 98, ME.
C:\Windows\Profiles\ on Windows 95, 98, ME.
How To Back Up Windows Registry ?
In windows NT, 2000 and XP not possible to back up registry files while the operating system is running. Registry files remain fully locked all the time while Windows is running, But hereYou can use an integrated Windows XP's System Restore feature for registry backup.
But using registry editor (regedit.exe) you can to export partial or complete copies of the registry, while the Windows is up, and the exported files can then be backed up with any other traditional file backup utility. You can follow these simple steps to back up the whole registry or any particular registry subkey:
* Click Start button and then type Regedit in Run option.
* Locate and then click the root subkey that contains all the child subkeys and values that you want to back up.
* On the File menu, click Export.
* In the Save box, you can select the location where you want to save the Registration Entries (.reg) file, type a file name in the File name box, and then click Save.
The exported registry file is about 10-50 MB in size on a typical Windows NT/2000/XP installation.
The Importance of Backup
If you are new computer user first you should learn about the importance and need of back up. Because without backup yon can lose your data any time due to any virus, power failure and hard disk problem. This has happened to many people. In extreme cases, it has put companies out of business. Computers are becoming more and more reliable. This creates a false sense of security - we begin to think all our data are safe and secure and will never go away. It's not true - and never will be. If you don't back up your computer system regularly. Backups are really a necessity, and you are responsible for making backups of your files.

Help to keep your computer secure.
I am often asked how a user can prevent them from getting viruses, junk email, diallers etc. The answer is it can be difficult and there is no single piece of software that will take care of the job for you. However there are some steps you can take to ensure that you do not fall victim to hackers and those "internet nasties".
Firewalls:
A Firewall is a piece of software (or hardware) that assists you to keep your internet connection secure. They vary in form and operation some put your computer in "stealth mode" by selectively blocking incoming connections into your computer. Others can even prevent unauthorised applications on your computer from accessing the Internet. If you are a Windows XP user then there is a firewall built into the operating system, this one only blocks incoming connections. There are others on the market, use your preferred search engine and look for firewalls.
Anti-Virus:
The anti-virus is the computer equivalent to a good dose of penicillin. These are often employed as a preventative measure to ensure that your computer does not become infected. If, however, your computer was to become infected then the anti virus program would enable you to preserve your system by either placing the infected file into quarantine or deleting the infected file. Also, in some cases, the file can be restored (the virus component removed). This is useful if the file that became infected was of some importance. If your system has been infected to such a state that it is impossible to boot and or work with the system then some anti-virus vendors produce stand alone virus cleaners, these are bootable disks that then scan and remove virus.
Spyware removers:
Today's internet surfing is not without countless perils and pitfalls, these nasty little annoyances come in many shapes and sizes, some are as "innocent" as cookies that track your surfing (a cookie is a small document placed on your hard disk that can record data) to fully fledged programs that install on your computer and take over your internet experience. The answer to this comes in the shape of a spyware remover, such as Spybot Search and Destroy. These programs scan your computer for spyware components and then remove them, but be advised some "free" programs (for example file sharing programs like bearshare) use spyware to pay for those programs.
Conclusions:
When you are on the internet or taking a file home to your pc remember that there are many ways a computer can become infected or make it's self vulnerable to attack, some sound investments in good anti virus and firewall software will help guard against these attacks, but above all be vigilant, if you get an email from some one you do not know with a file attached to it then do not open it, it may well be a virus.
Remember also that when you are surfing on the internet that there is a potential risk that you are "leaking" information. Look into spyware removal software, and be mindful about where and who you offer personal information to.

Alternative operating systems.
Today when we buy a computer most often it comes installed with Microsoft Windows; while that is okay for most users out there this can have cause for concern for those of us who like a little more choice.
Now today you can have that choice, firstly there is Microsoft Windows that as mentioned comes with most modern day computers, then there are the various forms of Linux out there and here is the surprising thing – most of them can be obtained for FREE.
That’s right, there is no charge for these systems and indeed the gargantuan amount of applications that are supplied with them are also free of charge.There is more too, most of these systems can be used as server’s too (a server provides file access, web access etc to other computers on a network).
In future entries we will take a closer look at the different Operating Systems in more detail.
