For anybody that refuses to stop using Windows 7, here are some utilities, applications, and other goodies that will still run on it, and in some cases, even XP! (And Vista.) Logos of each Windows version indicate that the application has been confirmed to run on it. No logos means it has only been tested on and at least runs on Windows 7. As these operating systems age and application support is dropped, this page will be updated to note the last compatible versions.
For more goodies be sure to check out the Windows Add-ons Archive.

This is one of the best, if not the best archive utility on Windows. You can work with the popular .7z format, as well pretty much every other archive format out there. It integrates well within Explorer, and is lightweight yet powerful.
This is a blue light filter to help you get better sleep.
This application can enable thumbnails for many different formats, though I primarily use it to get thumbnails for WebM video files.
This codec allows Windows to natively display thumbnails for WebP images and for them to be viewed in Windows Photo Viewer.

The Windows Media Format (WMF) is not by any means new, as it has been used for Microsoft Office Clip Art for a long time, yet Windows does not display thumbnails for these images. This little tool fixes that, although the images will still open in MSPaint.
The only caveat is that it requires you to purchase a license for unlimited, uninterrupted use. Other than that it can be pretty useful, even in free mode.
This little utility adds an icon to the notification area that shows you network activity, similar to how in functioned in XP.
This gives some improved window snapping functionality, making it more similar to what is found in many window managers for Unix-like systems. It's free for personal use, with some features restricted. The only downside is that it may occasionally nag you to upgrade to the full version.
Most modern browsers already have a PDF reader built in, but if you prefer a simple standalone PDF viewer with thumbnail capabilities and without all the bloat that Adobe's offerings provide, than SumatraPDF is a pretty good choice.
Now you too can enjoy this X Window System feature without switching over to a Unix-like operating system.
