I was trying to come up with a list of software that I “must have” on a new system (links to come hopefully later):

Dual boot Windows 7 x64 Pro/Ent/Ultimate with Ubuntu 11.04 x32
Inssider – Great for finding SSIDs, models of access points, security information, and channels of wireless networks
Angry IP Scanner – My favorite IP scanning utility is great for finding open web servers, DNS servers, or anything with RDP open
Putty – Terminal emulation software
FireFox – I still enjoy this more than Chrome, but they both have their place. Include Adblock Plus, Web Developer, NoScript, and GreaseMonkey with Youtube Auto Buffer and experts-Exchange
Terminals – My favorite RDP saving utility
CDBurnerXP – Burns ISOs, music, data
ISORecorder – Creates ISOs from folders or drives
CPUID’s CPU-Z and HWMonitor – Monitoring hardware in your system
NMAP-Zenmap GUI – NMAP for windows
WinSCP – SCP client for windows
Notepad++
NetIQ ADCheck
Filerfrog
TheDude
TightVNC
ThreatFire
Secunia PSI
Nod32
Filezilla
