It displays the following categories that all have several entries that can be tweaked: General, Services, Internet Explorer, Windows Media Player, Usability and Delete Files. The general and servies categories seem to be the most interesting ones. You can disable automatic windows updates, time synchronization and services like this there.

I don’t want to go over all of the dozens of settings that can be changed but want to point out some deficits of the software. The current version is not designed for beginners unfortunately. There is no online help and no balloon tip explaining what a setting does which means that you either have to know what you are doing or research the setting on the Internet before you change it.

There are however a few things that I like as well. It is a lightweight program not using lots of system resources and not that bloated like other Vista tweaking tools that I tested. I recommend Vispa to anyone who wants to change several settings in a short time.
