'ipconfig' is not recognized as an internal or external command, Windows 7

Sometimes uninstalling programs (worst case, viruses) could result in PATH in Windows environmental variables to loose track of some of main cores of the Windows system. E.g. if you run ipconfig in the CMD and gets this error: "'ipconfig' is not recognized as an internal or external command,
operable program or batch file.", then you might want to have a look at the PATH variable and see if  
C:\Windows;C:\Windows\system32
are missing ...

Adding a folder that is not on the frequent list, to pinned list in Windows Explorer

You can open folders from Windows Explorer shortcut on Windows 7. You have 2 lists when you right click on this folder, Frequent and Pinned. The frequent folders are those which you have visited frequently and the pinned ones are those which you have chosen to have it permanently in that list. It'e quite a useful shortcut, believe me.

One way to add folders to the pinned list is simply to choose them from frequent list and press the pin button in front of the folder name. However not all the folders that we would like to add to this list comes up in the frequent list. What to do? The solution is quite simple. You only need to drag that folder on the Windows Explorer shortcut on your taskbar  and release it. The folder would be added automatically to your pinned list.
