Gow (Gnu On Windows) is the lightweight alternative to Cygwin. It uses a convenient Windows installer that installs about 130 extremely useful open source UNIX applications compiled as native win32 binaries. It is designed to be as small as possible, about 10 MB, as opposed to Cygwin which can run well over 100 MB depending upon options.

Windows shell extension that adds SFTP support to Explorer.

130 command line utilities and counting. 10mb only.

Describes several very big hammers for hitting the fly of process-locked file handles.

Star Trek TNG's Lt Cmdr Data experiences a Blue Screen on his console and beats at it angrily.

Note: Now only works for Office documents; no images, no zip files. 50mb restriction is also still present. Doesn't seem to inspect files so it should store a zip file named with the .doc extension.

Port of the old "kvm" Linux screensaver for Windows. Includes source. Runs on multiple monitors.

Installer utility; silently installs your selection of software from the net with the best options selected (no toolbars, etc). Perfect for setting up new computers and keeping old ones updated.
