Something I love to do at Christmas is to decorate my computer with beautiful screensavers for the holidays. I look for the freebies most of the time, and there are a lot of them out there, some without adware, spyware, etc. which are the best, and some are wrapped with the stuff you really don't want on your computer! I love the animated ones with music. I have so many on my computer I could probably put a new one on each day for the whole month of December. I have a couple that are transparent snow which are really nice with a Christmas wallpaper under it. I used to have a program Snow for Windows, but lost that when my computer crashed. It had settings for how hard you wanted the snow to blow, and the snow would build up on windows, also settings for polar bears that walked across the screen, settings for Santa and his reindeer, and even for Rudolph and his shiny red nose.
You can download a 10 day trial version at http://snow-for-windows.en.softonic.com/ . It's for windows XP. I don't see anything about it being for windows vista, which is what I have now. Some other places for free screensavers are http://www.scenicreflections.com/. There are some nice 3-D savers here. If you hover over the picture, if it's free, it will state it's free. Downloaded many nice ones here and am having no trouble with my computer. Another place I've downloaded nice screensavers were from http://freechristmasscreensavers.com/christmassavers.html. Also http://www.freeze.com/. It's probably a good idea to always read the terms of use policy. These places may put their cookies on your computer, but as I said, so far I haven't had any problems. Some places during the install may want to put a toolbar on your computer and I always uncheck that box. You just have to read everything during the install. If there is something you don't want on your computer, uncheck the box if that option is available, or just cancel the install, and always, always, always, before installing, scan the download with your antivirus, antispyware program, then you can enjoy the beautiful holiday screensavers. Themeshack http://www.themeshack.net/group_projects.htm is always a safe place to get screensavers, but not all of them are free. You just have to hunt for them.
