An Apache SVN client, right where you need it most
TortoiseSVN is a Subversion (SVN) client, implemented as a windows shell extension. Which means it's available right where you need it: in the Windows file explorer. It's intuitive and easy to use, since it doesn't require the Subversion command line client to run. Simply the coolest Interface to (Sub)Version Control! NOTE: The project has moved to osdn.net: https://osdn.net/projects/tortoisesvn/
A disk usage statistics viewer and cleanup tool for Windows
WinDirStat (Windows Directory Statistics) is a disk usage statistics viewer and cleanup tool for Windows. On start up, WinDirStat reads the whole directory tree once and then presents it in three useful views: - The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size, - The treemap, which shows the whole contents of the directory tree straight away, - The extension list, which serves as a legend and shows statistics about the file types. Visit the WinDirStat blog for more up-to-date information about the program. Note: If you are looking for an alternative to WinDirStat for Linux, then you are looking for KDirStat (apt-get install kdirstat on Debian-derivatives), and the alternative to WinDirStat for MacOS X is Disk Inventory X or GrandPerspective.

Local Terminal Emulator
ConEmu-Maximus5 aims to be handy, comprehensive, fast and reliable terminal window where you may host any console application developed either for WinAPI (cmd, powershell, far) or Unix PTY (cygwin, msys, wsl bash). As Windows console window enhancement (local terminal emulator), it presents multiple consoles and simple GUI applications as one customizable tabbed GUI window with various features. Also, due to deep integration, ConEmu is the best companion for Far Manager, my favorite shell replacement. Disclaimer. ConEmu is not a shell, so it does not provide "shell features" like tab-completion, command history and others. But you can run any shell or remote access client of your choice in ConEmu! Try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. Or just run Bash from your favourite distro. Also, ConEmu does not provide remote access (SSH/Telnet/...) too, just use your remote client (ssh.exe, telnet.exe) instead.
