I found this info On the net for Screan savers:
SCR-files
If the downloaded file is of 'scr' type, you need to move it manually to c:\windows unless author's instructions tell you otherwise (sometimes needs to go to c:\windows\system or c:\windows\system32).
*Go to 'my computer', open c:\, then 'windows', then 'system32', and finally 'en-US'.
Alternatively you could just type C:\Windows\System32\en-US in your explorer window
To add a new screensaver, move the '.scr' programme to the 'en-US' file and then change the file from '.scr' to '.scr.mui'. Just tried it with the matrix one, and it worked fine (Windows 7). Alternately, in windows 7, you can right-click on the .scr file and click "Install" and it will install it for you.

Screensavers pre-installed with Windows can be removed as they are not essential to the proper functioning of Windows. It may be necessary, however, to change user permissions in order to subsequently delete the files.
www.screensaver.com/ has lots of screensavers of great variety. Simply access the site and you will see the large area of different screensavers. Simply click, and save.
Type regedit into the search bar under the Start menu. Open the program that comes up, and you see a list of folders. Screensavers will be found under: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Screensavers.
You can find screensavers for free if you go online and search up under screensavers. Most of the screensavers are free with your desktop or laptop computer.
There are many websites that offer cool screensavers with animals. These sites can be free, or a small fee is required so a large screensaver pack. Another option is you use the photos you have and use the features on windows to have a slideshow.
