This is the basic requirement which we want to add with in windows explorer while looking for any particular file or folder contained with in. What some time we want that the folder we have currently looking still remain to be open but any folder it contains open up a new explorer window using the right context menu.

So if you are also looking to do the same task then it is not so difficult to do if you are familiar with windows registry. Follow the steps given below

1.    Go to windows run command and type “regedit” without quotes.

2.    Now navigate to the key HKEY_CLASSES_ROOT\Directory\shell.

3.    Right click on Shell and select New -> Key and give its name as Open in New Window or with any name your want which will appear in right click menu.

4.    Now again right click on Open in New Window key and create its sub key with the name command.

5.    On the right side, double click Default and enter value explorer %1.

6.    Open in new Window option will come in right click menu of folder but to make it appear on drive as well create the same keys with same value but on HKEY_CLASSES_ROOT\Drive\shell.

Though this is a very useful tip but in case if you want to undo the above task just delete the entries created.
