Bins is a low cost ($4.99!) desktop enhancement for Windows 7 that will help you make better use of the space in your taskbar. Bins was created by the same person who created Fences -- which helps organize icons on the desktop. I've never been a huge fan of Fences because I like a clean desktop with only a few icons, so there is nothing to organize. My taskbar is a different story. I like having a large number of program icons pinned to the taskbar so I can easily start my most used software and because if you pin the software it's easy to find when you want to switch to it from another running program. Unfortunately, even on my Widescreen monitor there's really not enough space to pin all the programs I would like to. Bins solves this problem is an intuitive and useful way.
As I mentioned in my review of JP Software's freeware Take Command Console LE in February 2010, I used to use their old 4DOS program back in the days of DOS, Windows 3.1, and Windows 9x. 4DOS was the DOS Command Line on steroids: adding many features to the fairly primitive DOS command line.
Early versions of Microsoft Office used a multi-document interface. That is, if you had multiple documents open in Word, Excel, or Powerpoint you could switch between them using a tab bar within the Microsoft Office Application. Microsoft research apparently found that this confused new users who looked to their taskbar to switch between documents, so starting with Office 2003 Microsoft changed things so each document opened in a separate instance of the application and you switched between documents using the taskbar.
One of the nicer features of Windows Vista is independent volume control for every application. IndieVolume brings this feature to Windows XP (also ME, 2000, and 2003) -- and apparently has done so for several years. This program is payware, unlike most of the programs I review, but it provides a unique feature that I haven't seen in any freeware application.
If you've been using a computer for many years, you probably remember DOS and probably have an old DOS application or two that you really miss, but just does not run well under Windows XP. Your old DOS program just does not play well with Windows XP. It polls the keyboard constantly and never releases control to Windows when it idles, bringing every other application on your system to a crawl.
