PSPad – recently has been giving me problems with undo/copy/paste
SVN Client
RapidSVN – Small, lightweight, agile. Not as robust as others, but gets the job done and it’s quickness far outweighs any shortcomings. WinMerge recommended for browsing differences.
SSH/SFTP/SCP
PuTTY – The best SSH client. Recommend the Windows installer.
WinSCP – Easily copy files between the preferred SFTP protocol. Open, edit, and save changes on the fly.
MySQL
MySQL Workbench – Good for a simple query, but powerful enough to manage entire databases. Grant user permissions, view statistics, and more. Somewhat sluggish.
VNC/Remote Administration
UltraVNC – Robust VNC and a great “helpdesk” package creator to distribute to family and friends. They call the helpdesk creator “Single Click” (signle click documentation, creator).
TightVNC – Secure, frequently updated VNC client and server.
