Windows Screensavers Explained

Written by Roman Kramar

Continued from page 1

First, as you already know, screensavers are launched automatically byrepparttar operating system.

TIP: Be careful if you use CD-Burning devices regularly and your system is configured to launch screensaver after some period of inactivity. Some screensavers produce very sophisticated effects but forrepparttar 107849 price of intensive CPU load. If you leave your computer while CD-Burning software is working, screensaver will be launched. This can sometimes lead torepparttar 107850 CD-RW disks burned improperly.

During their installation process screensavers are copied torepparttar 107851 system directory (years ago users had even to copy screensavers by themselves). Once they are there, Windows finds them and puts inrepparttar 107852 list of available screensavers. You can see this list inrepparttar 107853 Display Properties dialog. But how doesrepparttar 107854 system know thatrepparttar 107855 program in its system directory is a screensaver? The answer is simple. Any screensaver program has a name ending with ".SCR" extension, while a typical program has an ".EXE" extension atrepparttar 107856 end. This isrepparttar 107857 first difference.

Second, almost every screensaver has a bunch of settings allowing you to change its appearance in many ways. This isn't a much difference because many typical programs have options and settings too. The difference lies inrepparttar 107858 way user invokes configuration dialogs. Windows providesrepparttar 107859 only way to do it. It'srepparttar 107860 Display Properties dialog mentioned above. Other programs usually have their own buttons or menus to do that. Why are we talking about it? It's simple. The whole process means thatrepparttar 107861 system has a way to communicate with screensavers: to launch them, preview and configure on your demand while other typical programs don't have it. Usually they are simply launched and that's all. This isrepparttar 107862 second difference.

So what? How can we use it to our own advantage? Imagine yourself downloading a new screensaver, running it and finding it rather amazing. The screensaver can be so amazing and entertaining, that you would like to show it running on your screen torepparttar 107863 friend of yours. But wait. How do you do that? What if your system is configured to launchrepparttar 107864 screensaver after 5 minutes of inactivity only? Or after 10 minutes or even more? Will you wait for this eternity? You can say that there is always a way to launchrepparttar 107865 screensaver fromrepparttar 107866 Dialog Properties. But in order to do that you should launchrepparttar 107867 dialog, findrepparttar 107868 Screen Savers tab and clickrepparttar 107869 Preview button. Quite a lot of things to do. And if you are willing to demonstrate two or even more screensaversrepparttar 107870 things get complicated even more. And what ifrepparttar 107871 screensaver you've found looks best whenrepparttar 107872 whole desktop wallpaper is seen onrepparttar 107873 screen? The Display Properties dialog will simply destroy this unique beauty you were willing to share.

Now imagine that double-clicking an icon on your desktop could do all this. Simple action, no unnecessary dialogs. Sure, some preparation steps are needed. But they are done once. After that you can enjoy launching screensavers using icons as many times as you wish. Is it worth doing? Try it,repparttar 107874 result can be very effective. Once you managerepparttar 107875 process, you can proudly call yourself a "Professional Screensavers User". If you likerepparttar 107876 idea then there'srepparttar 107877 way to achieve it:

1) Use Windows explorer to navigate to your system directory. Usually it is C:Windows or C:WindowsSystem if you are using Windows 95/98/Me. If you are using Windows NT/2000/XP, then you should look in C:WINNT or C:WINNTSystem32.

2) Look throughrepparttar 107878 list of programs there. It can be quite large, but you can easily findrepparttar 107879 name ofrepparttar 107880 screensaver you are looking for. Alternatively you can userepparttar 107881 "Find Files or Folders" facility.

3) Once you've found it, userepparttar 107882 right mouse button to dragrepparttar 107883 file ontorepparttar 107884 desktop. After releasingrepparttar 107885 mouse select "Create Shortcut Here" fromrepparttar 107886 popup menu. The icon forrepparttar 107887 screensaver should appear on your desktop.

Now you can launchrepparttar 107888 screensaver at any time. Simply double-clickrepparttar 107889 created icon. Enjoy! I will be glad if you feel a bit more control overrepparttar 107890 system.

Backup - How to Avoid a Disaster

Written by Emil Malmberg

Continued from page 1

Secure Online Backups After creating a computer backup you will probably storerepparttar backup on a CD, a shared file server or maybe even onrepparttar 107848 Internet. In order to protect you files it is often recommended that you use a password, or ifrepparttar 107849 backup contains sensitive information, you should use some form of encryption. WinBackup supports both password protection and strong encryption usingrepparttar 107850 AES 128 or 256-bit encryption standard. Encrypted backup files will be nearly impossible to open withoutrepparttar 107851 correct password can safely be stored on CDs and public servers. If you want to run online backups encryption is often critical to protect your data from unauthorized accesses.

A Network Backup System Corporate users as well as home users with local networks will often want to backup several computers to a server and then backuprepparttar 107852 server to a CD, CDRW or DVD. This can be achieved by schedulingrepparttar 107853 workstations to backup their files torepparttar 107854 server first, and then, after waiting for an hour or two, a scheduled bakup job onrepparttar 107855 server stores allrepparttar 107856 workstation backups to a CD Writer installed inrepparttar 107857 server. By layering backups this way you can easily backup entire networks and data can be restored by workstation users at any time sincerepparttar 107858 backup files for individual systems remain onrepparttar 107859 server. This technique can be very efficient and can save a lot of time for end users as well as IT departments.

Windows Backups and File Sharing Problems If you have ever tried to delete or rename an exe file that being executed, you probably know that locked files can sometimes cause serious problems. This is even more true when creating backups since many ofrepparttar 107860 files that you backup will probably be locked by other programs whenrepparttar 107861 backup operation is started. If you, for example, are using outlook when a scheduled backup operation starts,repparttar 107862 whole operation could fail ifrepparttar 107863 backup software attempts to lockrepparttar 107864 email database. WinBackup never tries to lock files and will continue a backup operation even if a file could not be read. Any missing files will be added torepparttar 107865 log and will be backed uprepparttar 107866 next timerepparttar 107867 backup job is executed. Since WinBackup doesn't lock files it will not prevent you from using your computer for other tasks while a backup operation is in progress. This is very important if you want to run scheduled operations inrepparttar 107868 background while you are working.
