Change Default Folder of Windows Explorer

Note: this will not work for explorer.exe from the START Button

1. Click on Start button, then go to All Programs, and finally Accessories. If you’re using Windows Explorer shortcut at other location, such as Quick Launch bar or Desktop, skip this step.
2. Right-click on Windows Explorer (or its shortcut) and then clickProperties.
3. In Windows Explorer Properties, click on Shortcut tab if you’re not already there.
4. The text box after “Target” by default will shown the value as below:
%SystemRoot%\explorer.exe
Change the Target text box parameter to the following:
%SystemRoot%\explorer.exe /n, /e,
where represents the full path to the new different folder that you want Windows Explorer to open as default folder on launch. The spaces must not be omitted.
For example, if you want Windows Explorer to run and show C:\ folder, the Target path should be like this:
%SystemRoot%\explorer.exe /n, /e, C:\
Or you if you want Windows Explorer to go directly to C:\MyFolder\directory, the line should read as below:
%SystemRoot%\explorer.exe /n, /e, C:\MyFolder\
A special case is to change the default setting so that all top–level drives and folders are shown. To show this folder view, use the following as Target shortcut so that when Windows Explorer is opened, you can choose from all the folders and drives, not just My Documents:
%SystemRoot%\explorer.exe /n, /e, /select, C:\
The above syntax for the Target with “/select” to open parent folder of the destination folder so that you can “select” from all folders (or drives) that are available on the same level of directory structures.
5. Click OK.
The trick works on most Windows operating system, including Windows XP and Windows Vista.
