Carapace

Carapace is a shell manager that was started as a hobby project some years ago now. It is still unfinished, but usable and stable. Using Carapace you manage multiple shell environments, and effectively run SharpE and Explorer together with very little effort. It can also be used to execute any application or game without first loading a shell, this way you have maximum memory available.

Wtf

WTF (What's This File) is a simple method of checking what's running on your machine, researching any Task found, and then ending the Task if required. Best of all, unlike many tools in it's class, you don't need to study a large manual to use it. WTF is freeware, includes an installer / uninstaller and like all RCMedia Services applications, does not contain any spyware, adware or backdoor nonsense of any kind.
