<p><b>Disabling Automatic Windows Update and System Restore</b> </p><p>There are certain services, such as Windows Update and System Restore, which load automatically and occupy a lot of space. If you want to disable them, right click on My Computer and choose Properties. Click on the System Restore tab and check the box 'Turn off System Restore'. This will increase Windows performance and save disk space. Just next to the 'System Restore' option, you will find the 'Automatic Update' option. This option will periodically ask you to update the OS. You can go ahead and disable this, but remember that you will have to update Windows manually after applying this option, and there will be no further reminders. </p><p><b>Change the picture on the welcome screen</b> </p><p>Want to add your own picture in the Startup menu? Go to Start > Control Panel > User account and click on the user name. There you will see an option to change the picture on the welcome screen. On clicking it, you will see an option from which you can select the picture already present or you can browse to the folder where you've saved your photograph. </p><p><b>Creating personal screensavers </b> </p><p>You can use your photographs for creating slide show presentations or even creating a screensaver. Right click an empty spot on your desktop, choose Properties, and click the Screensaver tab. In the Screensaver list, click on 'My Pictures Slideshow', and click 'Settings' to make any adjustments-such as how often the pictures should change, their size, and whether you would like to use transition effects between pictures. Click OK to finish. The screensaver that will now be generated will display photographs from the My Pictures folder in a random manner.</p>
