Image resizer is a power toy tool that can be downloaded from microsoft website. www.microsoft.com/windowsxp/downloads/powertoys/
xppowertoys.mspx

As the name suggests, 'Image resizer' is used to resize the image files in our computer. These images can be a JPG, BMP or other image format files. Once you download this power toy tool from the above webpage and install it in your computer,

1. you can open the windows explorer and select a few image files and right click to see a menu.
2. From this menu select 'Resize pictures'
3. Then select the preferred size that you want for these selected pictures
4. Then click 'Ok' to save all these files with the size you selected.

Though this tool is very easy to use, you may still have to make some settings to tune this tool. You can only resize the pictures into four different sizes. In this, the first three sizes can be used to resize the photos or pictures in landscape format. The fourth option, 'Handheld PC' can be used only with Pocket PCs.

If you need to fine tune this tool, do not use the 'default size' option. Instead select 'Advanced' and select the 'custom option'. For both 'portrait and landscape' type of pictures select the maximum size of pixels (resolution). In both boxes use the resolution that you selected. This is the maximum size therefore do not worry that all files will be resized to this. Usually 600x800 size is suitable for sending emails and storing in websites. However if you need to print it out then select higher resolutions.

Your high resolution original pictures will be renamed and retained by Image Resizer, therefore do not worry that resizing will delete the original files.

In Windows 3.1 and Windows 3.11 versions of windows which are now obsolete there were many INI files used by the Operating System. These INI files containted details of different hardware and applications installed in the computer.

But in Windows 95, Microsoft introduced the concept of 'Registry'. In these registries, windows stored details and settings of all the hardware and applications.

All the windows versions starting from Windows 95 followed this Registry style. Windows 98, ME, NT, 2000 and XP use these registries.

In today's Windows Operating System, Registries play an important role. If due to some reason these registries get corrupted then the whole computer becomes unusable and cannot even boot the system. If you had the backup of registries then you can restore these registries and make your computer function again.

You never know when these registries get corrupted. Therefore it is a good practice to backup your registries every now and then, so that when required you can use this backup to restore your registry settings.

Registry in Windows 95/98/ME

In Windows 95 and 98, System.dat and User.dat are two important files. The reason is these two files are the registries. In Windows ME a third file namely Classes.dat was included as part of the registry.

These three files are usually located in the 'Windows' folder. So if you use Windows explorer, goto 'Windows' folder and copy these three files to another folder then the backup of registry is done.

Microsoft has provided an utility for backing up registries called ERD. In your Windows CD this utility is there.

Moreover, Windows 95,98 and ME backs up the registry on startup.

Registry in Windows NT, Windows 2000 and Windows XP.

Those Windows Os that are based on the NT Kernel such as Windows NT/2000/XP do not backup registry on its own. Therefore you have to backup manually if you are using one of these windows versions.

It is not an easy task to backup registry in Windows NT/2000/XP. There are many files such as Default, Sam, Security, Software and System that constitute registries. They are found in the System32/Config folder. Since these files are used by the OS, you cannot copy these files.

In Windows NT you can use Regback Regrest NTBACKUP utility to backup and restore registries.

In Windows XP you can use System Restore utility to backup and restore utilities.

In Windows NT/2000/XP chances of registry getting corrupted is very less. Maybe that is the reason why Microsoft does not provide easier methods to backup and restore registries in these versions of Windows.

http://home.t-online.de/home/lars.hederer/erunt is a free software that you can download and use to backup and restore registries in Windows NT/2000/XP. utility to backup registry and utility to restore back the registry. In Windows 2000 you can use the

When you bought the computer the engineers may have given these advise to you. Or when there was some problem in the computer and you went for repair the support engineer may have cautioned you about these tips. You may even have tried these once and then forgot about it. It becomes a MUST to keep your harddisk healthy and clean for your computer to function properly at all times. Therefore I advice you to print these tips and paste it in your computer room so that you always remember to follow these advice.

1. Virus Scan: At least every fortnightly you should scan your computer for viruses. Or atleast configure your Anti-virus software to auto scan at preset intervals. Almost all the Anti-virus software comes with this scheduled scanning feature. This is called AutoProtect. Set this feature ON. Likewise if there is a virus then what to do, do you want to delete it, if not possible to delete then quarantine it etc. You can set these options in your Anti virus software. Also remember to update the virus definition files of your Antivirus software often. Or select the 'Live Update' option so that the Antivirus software is always upto date.
   
2. Another essential software you should have is 'Adware / Spyware' removal program. Though this is not as important as the Anti virus software it is better to have a Adware Spyware removal software. Only then you will be notified of malicious spy programs that spy on your private information. ZoneAlarm is a free software that detects Adware and Spyware in your computer. So download and install this free software.
   
3. Some unwanted files occupy your harddisk space. Your computer will detect these unwanted files and delete them to free your harddisk space. For this you have to do 'Disk cleanup'. In your windows explorer select 'C' drive and right click and choose 'properties'. In the new window that opens, you will see a small pie chart which shows how much of your hard disk is currently occupied and how much is free. In this window you will see the 'Disk cleanup' button. If you click on this the Disk cleaning process will start. It will show you how much space can be freed. If you are doing this first time, you will be surprised that the unwanted files occupy so much space.
   
4. Due to curiosity you may have installed many programs and applications in your computer. Some of the applications you may have used once or twice and may have forgotten about the application. It is a good practice therefore to remove these unwanted applications from your computer every now and then. To do this, goto Start,Control Panel and click on 'Add/Remove Programs'. In the 'Add/Remove programs' window you will see a list of all the programs installed in your computer. It will also show you when was the last time you used each program. Here you can select the unwanted application and uninstall.
   
5. You can also manually look in to your 'My Documents' folder or any other folder that you frequently use to store your files and see if there is any unwanted file and delete it.
   
6. If you use 'Outlook' to view your emails then all your emails get stored in your inbox and trash folder. You can clear unwanted emails from outlook to save a lot of space.
   
7. Similarly you can also clear history from your internet explorer. Your browser keeps in history some files from each website you visit. So if you have not cleared history files from internet explorer for quite some time then it may occupy a lot of space in your harddisk. Therefore it is best to goto 'Tools,Internet options' and then 'Delete Temporary internet files' and clear history from there. You may also 'Delete cookies' and 'Delete Files'.
   
8. You may have kept shortcuts to many programs and applications in your desktop. It is a good practice to keep your desktop clean by deleting unwanted icons from desktop. Remember that deleting shortcuts does not delete the application. You should uninstall the application from 'control panel->Add remove programs'.
   
9. Also remember that just deleting files DOES NOT free space. Because windows will store all the deleted files into 'Recycle Bin'. So you have to 'Empty the recycle bin' in order to delete the files permanently and free space in your hard disk.

After using computer when you shutdown windows, you may sometimes wonder whether you can make the shut down faster. Even those who play games for 3 or 4 hours at a stretch will be impatient to wait while waiting for shutting down. Some may complain, 'my computer takes very long time to shut down'. There is way to make your shutting down time shorter.
Follow these steps to make shut down time to 5 seconds.

1. In a blank space in your desktop, right click and select 'New / Shortcut'.
2. In the 'Create shortcut' window in the 'Type the location of the item' box type shutdown and then leave a blank space and type the command as shown below.
3. If you use Windows 95/98 or ME then type c:\windows\rundll.exe\user.exe exitwindows
4. If you use Windows XP then type c:\windows\system32\shutdown.exe -s -t -05
5. The system will alert you that the system will shutdown in 5 minutes. If you want to make it longer then change the seconds as you want.
6. Now click 'Next' and type a name for your shortcut
7. Now click 'Finish'.

What you have done is, to create a shortcut for the program 'Shutdown.exe' and to execute it with your own preferences. This file is usually available at %systemroot%system32 folder.

While your computing is booting, you can instruct the computer to boot in 'safe mode'. Safe mode refers to secure mode. You may then ask, is our computer not secure when we boot normally. Let us see how is safe mode more secure than the normal booting.

When your computer gives problems and you want to identify where is the problem, then you can use the safe mode for this. In safe mode, only limited number of driver programs are enabled. Therefore you cannot use CD drive. You cannot use the printer. And many other unnecessary drivers are not enabled.

While in Safe Mode, you can use the ScanDisk, defrag and other utility programs to repair your computer. You may wonder how to bring the computer to safe mode. When Windows boots up, you have to press the F8 key. You should press the F8 key before the windows screen appears. Then you can choose the safe mode option to boot.

Some Anti virus software will tell you that some viruses can only be removed in safe mode, therefore the antivirus software will automatically start in safe mode or you may have to goto safe mode and then run the virus removal utility to remove the virus.

We use internet for many purposes. In many websites we use different login names and passwords. For example, if you use any of the free web emails such as gmail, yahoo or hotmail then you will have to login with your login name and password before accessing your email inbox.

Similarly, if you use any commercial websites for internet shopping such as Amazon or eBay then you may have to use your credit card details before buying online. Only then can you buy online. If we lose credit card related information then we may lose money. If this information falls into the hands of hackers then we are seriously at danger of losing money. This hacker can then use your credit card details to buy anything.

Worse still, if someone uses your login name and password to login to a server and carries out any destructive activities then you will be blamed for that activity. Court trial or penalties or fine may make your life miserable.

The password, credit card details can be stolen from three places.

From your computer, when you type in your browser these key strokes can be captured

Or while this information packets are transmitted from your computer to the server. This is called 'Wiretapping'. Hackers and crackers can easily accomplish this.

From the web server's database. In this database, like your data, many people's information will be stored. If the hacker gains access to these databases then he can get these data.

Of these, the first and the second method of stealing can be prevented by you. The third way of stealing from web server, is not in your hands and you can not do anything to prevent it. Let us see how you can prevent the first two methods of stealing.

The login name, password and credit card details that you type in your browser are sent as text via internet to the web servers. The hackers and crackers can easily read this text. They cannot read it if it is encrypted. This is where Secure Sockets Layers are used.

Whether the web server that you are connecting to, uses SSL to encrypt the data can be found from your browser. For example a 'closed lock' icon will be displayed in the status bar of your browser. If there is not clocl icon in the status bar then those websites do not use SSL and therefore not secure.

In your 'Internet Explorer' choose 'Tools-Internet Options'. In this new dialog box select the 'Advanced' tab. Here, you will see many check boxes under the security section. 1. Use SSL 2.0. 2.Dont save encrypted pages to disk 3. warn if form submitted is being redirected 4. warn if changing between secure and not secure mode. 5. check for server certificated relocation 6. warn about invalid site certificates. See that all these six options are selected.

From now on, the browser will prompt your, whenever you enter/view websites whether that page is secure, and when you type any details, whether the data is encrypted or not.

In login pages, when you key in the first two or three letters of your username, Internet explorer will auto complete the username and password to make it easier for you. But this feature can be a problem if many people are using the same computer. Others may enter into your account just by typing the username and without even knowing your password. So it is better to 'TURN OFF', 'Auto Complete' feature. To do this, select 'Tools-Internet Options'. Choose the 'Content' tab and click the 'Auto complete' button. Click on the 'Clear passwords' button and delete all the stored passwords. If the 'Usernames and passwords on forms' check box is selected then de select it.

Also clear all the cache files from your browser. To do this select 'Tools-Internet Options'. Select the 'General' tab. In the 'Temporary internet files' section click the 'Delete Files' button. Now click on 'Yes' and 'OK'.

Congratulations, now you have reduced the possibility of your passwords to be stolen
