Windows: Unlike previous versions of Windows, Windows 7 has no option for remembering the position of individual windows. If you miss having Windows remember how you arrange things, ShellFolderFx can help.
It's a small thing, certainly, but if you'd grown used to Windows keeping track of the size and position of your windows — especially important for multi-monitor users! — then the removal of that feature in Windows 7 was more than a minor annoyance.
ShellFolderFix is a small application that allows you to enable folder and size position saving as well as maintaining folder browsing history between sessions. Once you set the options you want and send the application to the system tray you never need to bother with it again, it runs in the background keeping track of the folders and restoring them to their respective positions.
For another way to get a piece of Windows history back in Windows 7 check out how to get the classic network activity indicator back in Windows 7. ShellFolderFix is freeware, Windows only. Have a trick or application for restoring functionality from past versions of Windows to Windows 7? Let's hear about it in the comments.
