I found this site because someone pointed me there for a replacement for Windows Task Scheduler (which I can't get to work properly).
All the programs on this site have free versions, and some have Pro versions with added functionality.
A couple of interesting ones are:
Launchkey - Command line tool to launch an application and send it keypresses. Useful to run from batch files or from other applications.
Clipboards - Trayicon utility to give you more than one Windows Clipboard. Switch easily between clipboards.
SystemScheduler works great and it much easier to use than Windows Task Scheduler (plus it has the benefit that it works!).
