Cygwin is a Linux-like environment for Windows. It consists of two parts:

WinMerge is an Open Source visual text file differencing and merging tool for Win32 platforms. It is highly useful for determing what has changed between project versions, and then merging changes between versions.

KDiff3 is a program that

• compares or merges two or three text input files or directories,
• shows the differences line by line and character by character (!),
• provides an automatic merge-facility and
• an integrated editor for comfortable solving of merge-conflicts,
• supports Unicode, UTF-8 and other codecs, autodetection via byte-order-mark "BOM"
• supports KIO on KDE (allows accessing ftp, sftp, fish, smb etc.),
• Printing of differences,
• Manual alignment of lines,
• Automatic merging of version control history ($Log$),
• and has an intuitive graphical user interface.
• Windows-Explorer integration Diff-Ext-for-KDiff3 - shell extension included in installer...

MP3Ext is an extension for the Windows Explorer.
It enhances it, so you can get information in many ways.

smartision ScreenCopy is a freeware and opensource screenshot tool for Windows developed in Borland Delphi. It has many features like Auto-Screenshot and an included Gallery Generator.

Memtest86 is thorough, stand alone memory test for x86 architecture computers. BIOS based memory tests are a quick, cursory check and often miss many of the failures that are detected by Memtest86.

eXtended FDisk, or short XFDisk, is a free DOS FDISK replacement that offers more comfort and comes with a bootmanager that allows you to have more than one operating system installed on your hard disk. With XFDisk you can partition your hard disk or install and configure the bootmanager, which will be located in the first 17 sectors of your first hard disk. The bootmanager will not occupy an own partition, so you can fully use the four available primary partitions per hard disk. If you choose to have an extended partition with logical drives on your hard disk, XFDisk transparently manages the extended partition for you. So you don't need to worry about the size of the extended partition any more. Of course, XFDisk and the bootmanager support more than one hard disk and even booting from logical drives. But it must be said clearly that most operating systems that are commonly used on PCs require a primary partition on the first hard disk at least for their boot files. This is true for all versions of DOS and Windows 95/98/ME, but it is also true for Windows NT/2000. However, some operating systems like Linux or OS/2 can boot from virtually any hard disk, even though OS/2 may need its own bootmanager for installation.

Virtual Dimension :: a free, fast, and feature-full virtual desktop manager for Windows platform. The main goal of this open-source project is indeed to enhance the Microsoft "Window Manager" up to the level of usual Unix Window Manager, by providing virtual desktops, as well as some additional features, like always on top, window shading...

VirtualWin provides virtual desktops for the Windows operating system much in the same way Linux/Unix does.
