You can add an Internet URL address bar to your Windows XP taskbar. Doing so will let you type in URLs and launch Web pages without first launching a browser. Here’s how you add the address bar:
1. Right-click on the taskbar, select Toolbars, and then click Address.
2. The word Address will appear on your taskbar.
3. Double click it to access it.
4. If that doesn’t work, your taskbar is locked.
You can unlock it by right-clicking on the taskbar again and uncheck Lock the Taskbar. You may also need to grab the vertical dotted lines beside the word Address and drag it to the left to make the Address window appear.
mains reasons why PCs crashes is as follows
Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
Bad Ram
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.But a fatal error caused by Ram might be caused by a mismatch of chips.
BIOS settings
Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.
Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze.
Viruses
First sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk.
If you want to encrypt the contents of an individual file or directory, Windows XP Pro will do the trick, provided you enable NTFS on your hard drive.
To encrypt a file, right-click on it to bring up the Properties window. Click on the Advanced button, then in the Advanced Attributes dialog box click on Encrypt contents to secure data. This will encrypt the file (using either DES, which employs a 56-bit key on each 64-bit block of data, or 3DES, which uses a 56-bit key three times on each 64-bit block of data), and it will provide a certificate just for you. This certificate is key; if you reinstall Windows or otherwise lose your user account, your access to the encrypted files will be gone, too. You need to export your certificates to back them up: For detailed instructions, search on export certificate in Windows Help.
Windows XP Home doesn’t support this method. Both XP Home and XP Pro, however, let you create password-protected compressed files. To do this, right-click on the desired file and choose Send To Compressed (zipped) Folder. Open the resulting folder and select Add a Password from the File menu; delete the original file.
Note that this encryption is relatively weak. It should dissuade casual users but won’t put up much of a fight against someone determined to hack it apart.
