Publishers Note :
Customize the look and feel of Windows XP with WindowBlinds. It's a Windows utility that enables users to personalize nearly every aspect of the Windows graphical user interface. It can "skin" your title bars, push buttons, Start bar, radio buttons, and nearly every other part of Windows. There are thousands of freely available skins to choose from. Use WindowBlinds to make Windows look like another operating system (Mac, Linux, etc.) or give it your own unique look and feel. You can also create your own skins using the freely available SkinStudio. WindowBlinds eliminates the need for any stay-resident program making it use virtually no extra memory. It also makes use of hardware acceleration found on most nVidia and ATI cards resulting in an overall performance increase. WindowBlinds 5 also supports per-pixel alpha blending allowing for "glass" effects, semi-transparent titlebars/borders, smooth borders.
Version 5 adds per-pixel alpha blending. This means that title bars and borders and menus and other GUI elements seamlessly blend in to what is around them. Glassy skins, skins with very smooth edges, and irregularly shaped menus and other pieces become possible.
My Review :
Pros: I was a huge fan of WindowBlinds 4.5. It was really a great program for skinning Windows with. Now, Stardock has outdone itself with this update. The capabilities that it adds are incredible. The visual capabilites have been updated, and now the themes include transparency, irregular shapes, glowing effects, and more. The stock options for themes are good, and you can download even more at the wincustomize.com website. This version makes your computer look and feel like any OS you want. The compatability issues have been improved. The program runs faster and smoother than previous versions. It also uses less resources. Some of the display quibbles are gone now, too. I have always felt that this was the most sophisticated skinning program out there, but now it is the best, hands down! And if you have the purchased version, you will get even better features out of this program.
Cons: The trial used to be unlimited, now it only lasts for 60 days, and it has limited skinning capabilities for that trial. That is generous for a trial, but compared to what it used to be, that is kind of rough. Also, the unregistered product begs you to buy it at each startup. I think it is well worth it though. Some programs that skin themselves may act a little strange with this. Still, for the depth and excitement that it adds to the boring Windows shell, you simply must give this download a chance. It breathes life into your PC, and will make you feel as if you have a new OS again!
