Microsoft has a free edition of Microsoft Expression, which has the basic functionality of creating screencasts. This way you can create screencasts, and encode them to WMV (or to Silverlight). The free edition is limited to 10 minutes per clip, but this should be adequate for simple short clips.
Microsoft Expression Encoder can be downloaded from the Expression website: http://www.microsoft.com/expression/try-it/; scroll to the bottom to find it.
It never was easier to get rid of those pesky ads in Windows Live Messenger. Simply download A-patch: http://apatch.org/.
By default, 7-Zip SFX (self-extracting executable) creation only has basic configuration options. With 7-Zip SFX Maker, you can expand those options with a whole lot more.
This piece of software allows the creation of customized SFX, taking 7z files as input. Things like changing the icon, captions, default extraction path and more, are all implemented. This makes 7-Zip SFX Maker a handy tool when you require a little more than a standard SFX but less than a fully-fledged installer.
