Here is list of must have tools listed by Scott Hanselman's ComputerZen.com

• THREE WAY TIE: Notepad2 or Notepad++ (Scite also uses the same codebase) or E-TextEditor - The first two are great text editors. Each has first class CR/LF support, ANSI to Unicode switching, whitespace and line ending graphics and Mouse Wheel Zooming. A must. Here's how to completely replace notepad.exe. Personally I renamed Notepad2.exe to "n.exe" which saves me a few dozen "otepad"s a day. Here's how to have Notepad2 be your View Source Editor. Here's how to add Notepad2 to the Explorer context menu. E-TextEditor is new on the block this year, inspired by TextMate in the Macintosh. It includes a "bundle" system that uses the scripting power of the Cygwin Linux-like environment for Windows to provide a more IDE-like experience than Notepad2 or Notepad++. It costs, though, but you should absolutely try it's 30-day trial before you shell out your US$35.
  
  
  
  
  • Notepad++ is built on the same fundamental codebase as Notepad2, and includes tabbed editing and more language syntax highlighting. Is one better than the other? They are different. I use Notepad2 as a better Notepad, but more and more I find myself using E-TextEditor aka TextMate for Windows when I need to crunch serious text. As with all opinions, there's no right answer, and I think there's room for multiple text editors in my life. These are the three I use.
  
  
• PowerShell - The full power of .NET, WMI and COM all from a command line. PowerShell has a steep learning curve, much like the tango, but oh, my, when you really start dancing...woof. I also use PowerShell Prompt Here.
  
  
  
  • I also recommend after installing PowerShell that you immediately go get PowerTab to enable amazing "ANSI-art" style command-line tab completion.
    
    
  • Next, go get the PowerShell Community Extensions to add dozens of useful commands to PowerShell.
    
  • If you're willing to pay (and wait a little) keep an eye on PowerShell Plus. I'm on the beta, and while it'll cost a reasonable fee, it'll be amazing. Certainly not required, but very shiny.
  
  
• Lutz's Reflector and its Many AddIns - The tool that changed the world and the way we learn about .NET. Download it, select an interesting method and hit the space bar. Take the time to install the Add-Ins and check out the amazing static analysis you can do with things like the Diff and Graph.
  
• SlickRun - A free floating dynamic "command prompt" with alias support that continues to amaze. My tips for effective use: read the instructions, edit the slickrun.ini file and bind it to Window-R. Also set ChaseCursor so when you hit Win-R, you'll have a floating transparent command line anywhere your mouse is. I recommend you also use larger fonts! Get to know this little box. It's the bomb. I've tried dozens of launchers, giving each days of actual use, but I keep coming back to SlickRun.
  
  
• FireBug - Arguably the most powerful in-browser IDE available. It's a complete x-ray into your browser including HTML, CSS and JavaScript, all live on the page. A must have.
  
• ZoomIt - ZoomIt is so elegant and so fast, it has taken over as my #1 screen magnifier. Do try it, and spend more time with happy audiences and less time dragging a magnified window around. Believe me, I've tried at least ten different magnifiers, and ZoomIt continues to be the best.
  
• WinSnap and Window Clippings - I'm torn between two of the finest screenshot utilities I've ever found. Free, clean, fast and tight, WinSnap has as many (or as few) options as you'd like. Also does wonders with rounded corners and transparency. It includes a 32-bit and 64-bit version, as well as a portable no-install version. However, Window Clippings also has no install, includes 32 and 64-bit and is only $10. It's a tough one. I use Window Clippings at least daily, and I use WinSnap a few times a week. Kenny Kerr of Window Clippings is actively adding new features and has a nice clean add-in model on his Developers site. Both these apps are worth your download.
  
  
• CodeRush and Refactor! (and DxCore) - Apparently my enthusiasm for CodeRush has been noticed by a few. It just keeps getting better. However, the best kept secret about CodeRush isn't all the shiny stuff, it's the free Extensibility Engine called DxCore that brings VS.NET plugins to the masses. Don't miss out on free add-ins like CR_Documentor and ElectricEditing.
  
• SysInternals - I showed specifically ProcExp and AutoRuns, but anything Mark and Bryce do is pure gold. ProcExp is a great Taskman replacement and includes the invaluable "Find DLL" feature. It can also highlight any .NET processes. AutoRuns is an amazing aggregated view of any and all things that run at startup on your box.
  
  
  
  
  • A great new addition to the SysInternals Family is Process Monitor, a utility that eclipses both Filemon and Regmon. It runs on any version of Windows and lets you see exactly what a process is doing. Indispensable for developing.
    
  • It's also worth calling out the legendary Process Explorer as a standout and must-have utility.
  
  
• FolderShare - It takes a minute to grok, but FolderShare lets you synchronize folders between systems, between OS's, behind firewalls. Truly change the way you use your machine. Save a file in a folder and it will always been on your other three machines when you need it. Also access files, if you like, from remote locations. And it's free.
