a few questions before buying

Since I don't work for them, this is not a official Stardock answer, but it is a reliable one.

1. is there an activation limit?

Yes to a degree. If you hit your limit, support will reset it for you.

2. do you have to pay each time it gets an update?

No, if you buy the stand alone version of Windowblinds, you get free updates until the next number version release. It's currently at 7, the next version release will be 8.

3. will I be able to install it on 2 maybe 3 computers? (Main computer and laptop) without the original computer or other computers giving me activation errors?

You are allowed to install on two machines as long as you are not using both at the same time and they are owned by you.

4. do people still make themes for it? (I remember using it in the XP days and loving it)

Yes, there are new additions to the gallery all the time.

That was for the WindowBlinds stand alone.

You could get the Object Desktop Subscription and get Windowblinds plus a whole lot more....

Object Desktop is a suite of desktop enhancement utilities designed to let users turbo-charge Windows.

The core programs of Object Desktop 2010 include:

WindowBlinds A program that can customize the look and feel of the entire Windows graphical user interface by applying new “skins” that change title bars, taskbars, scrollbars, and nearly every other part of Windows.

DeskScapes A program that lets users customize their wallpapers or even apply animated wallpapers (there are hundreds of free animated wallpapers available to choose from).

Fences Pro A program that lets users organize the icons on their desktops into groups of easily manageable “fences”.

Tweak A program designed to make it easy to modify various hard to find Windows settings and control what gets loaded (or not loaded) onto your system.

IconPackager A program that can apply new icons themes by loading up a package of icons.

SkinStudio A program that makes it easy for users to create their own user interfaces to apply to Windows.

Theme Manager A program that ties it all together. Get your desktop just the way you want and save it or apply themes created by others that include WindowBlinds, IconPackager, DeskScapes and other customization program content.

In addition Object Desktop users get a host of other programs to enhance Windows such as DesktopX, WindowFX, IconDeveloper, SoundPackager, Keyboard LaunchPad, and more.

Users of Object Desktop don’t just get what is in Object Desktop today but also everything released or updated for it in the year after purchase. Even now, Stardock’s developers are working on programs that can give new options to Windows 7 users, get the most out of Windows XP, Vista, and more.

Object Desktop is only $49.95. For users who want to keep getting updates to the programs after the first year, they can renew their access for only $34.95!
