Windows 7 x64 *must have* Apps?

[varulv]

Greetings,

Recently got myself a new PC, specs below:

CPU: core i7 960
GPU: GTX 295
Mobo: Intel DX58SO
Ram: 3x2gb kingston hyperX memory
Soundcard: SB X-FI Titanium Fatality Pro
and my beloved Intel X25-M 160GB SSD
OS: Windows 7 x64 ultimate

Now, i've been wondering if you guys can recommend any nice applications like a registry/maintnance program.. that kind of stuff.Whatever comes in mind
At the moment i've only installed Ccleaner but i don't know if its enough.. also Eset smart security and i must say that i'm kinda happy with it.
