WindUpdates is Spyware created by 180solutions, though it is not branded as such. It is distributed via ActiveX installations while visiting 3rd party websites, and bundled as an ad-support with 3rd party software. Some rumors also claim it is distributed by exploiting security flaws.
The EULA states that without limitations, 180solutions is allowed to install new features in its current applications, or to install a new application without the user's knowledge or consent. This information is hidden deep in the EULA, so that the average user would not find this clause. Such behavior is rated as a high security risk.
WindUpdates displays advertisements, customized based on the surfing habits of the user. Arbitrary data is also communicated to 180solutions servers.
Looking at the WindUpdates homepage, we see that the software has no purpose besides delivering pop-up advertisements.
