Windows tips

                              Create a link to shutdown your PC
To create a useful link desktop link to shutdown or restart your PC, follow these directions: Right click on an empty area of your desktop, then select 'new' and 'shortcut' to open the new shortcut wizard. When prompted for the location of the shortcut, enter 'SHUTDOWN -s -t 01' to shutdown the system or 'SHUTDOWN -r -t 01' to restart the system. Name the shortcut and give it an appropriate icon from the '%SystemRoot%\system32\SHELL32.dll' location. 

                            Rename multiple files simultaneously 
In windows XP explorer, you can rename multiple files at the same time simply by highlighting all the files you wish to change, right clicking one of them and selecting 'rename.' Once you have done this, all the files will share the same name with a number in brackets differentiating them 
     Hosting online games through the Windows XP firewall
If you are using the Windows XP firewall and you wish to host an online game such as Quake 3, or other applications that require users on the Internet to contact your computer directly, you will need to customize your firewall slightly to allow these specific communications through. Fortunately the XP firewall makes these changes fairly easy to do. To customize your firewall: Go to 'start\control panel\network connections'. Right click on the network connection that has the firewall enabled and go to 'properties.' Choose the 'settings' button at the bottom. On the 'services' tab, click the 'add' button.

This window will add the application that you are using to the firewall's list of data that is allowed into your computer. You will need to find out the port that your application uses. This information should be available from the documentation or from the software manufacturer's website. Input a description for your convenience, then the computer name or IP address of the computer that is hosting the program, then put the port number that the program uses. Note that as long as the program is running on the computer that uses the XP firewall, the internal and external port will be the same. Click 'ok' to apply the rule. Your firewall will now allow connections through the port you specified.                    Compressing files and folders to save space
Windows XP includes a built in compression utility which can save you some valuable space on your hard disk by archiving little used files. Working similarly to compression programs such as PKZIP and WINRAR, the built in software reduces the space your files take up on the disk at the penalty of increased disk access time for the compressed files in question. There are several ways of compressing data on your system: If you have a pre-existing folder and would like to compress everything in it, right click on the folder, select 'properties' then the 'advanced' button at the bottom. In the 'compress or encrypt attributes' section, check the 'compress contents to save disk space' option.

If you wish to create a compressed folder for a file or folder separate from the one it is in now, right click on the item you wish to compress and choose 'send to\compressed (zipped) folder.' This will create a new compressed folder in the same location as the original file or folder.                                          Enable clear type
Windows XP allows you to enable Microsoft's Clear Type font smoothing method. This blends the colours at the edges of type on screen, causing the letters to appear less jagged. While it is primarily intended to increase text quality for users of laptops and desktop PCs with LCD (flat panel) screens, it is worth experimenting with even if you use a traditional CRT.

Be advised that certain ClearType settings may appear rather blurry on a CRT monitor. If you use an LCD monitor on a laptop or desktop, you should definitely enable Cleartype as the increase in text quality is considerable.

To activate ClearType: Go to 'control panel\display' and select the 'appearance' tab.Click the 'effects' button. Ensure that the 'use the following method to smooth the edges of screen fonts' box is checked and change the drop down box to 'ClearType.' Press 'OK.'

Once you have enabled cleartype, Microsoft has provided a web location where you
 can fine-tune your ClearType settings.here is the link
        Resize screen fonts on the fly in Internet Explorer 
Here's a simple useful tip that you can use in Internet Explorer. While viewing a web page, hold down CTRL and use the scroll button on your mouse to increase or decrease the size of the fonts on the page. Some websites really like using the small size 1 fonts, and if you're eyes have a hard time reading such small text, this little trick can make previously headache ridden websites much easier to read through. 
            Increasing desktop Graphics Performance
If you are running Windows XP on an older computer, you may find turning of some of the graphical frills that XP uses to render the desktop will improve the 'snappiness' of your computing experience. To see a list of these effects so that you can experiment with the effectiveness of turning them off:

Right click on 'my computer' and hit 'properties.' Choose the 'advanced' tab. In the performance section, click the 'settings' button.

A list of the various graphical effects that can be turned off or on is shown. To turn them all off, you can choose the 'adjust for best performance' button. Play around with these settings and see what you think.
