Yes.
An alternative to all of the above (for both Win 7 and Win 8) is to navigate to a convenient folder (using File Explorer), then SHIFT-RIGHT click in the file listing of that directory and pick "Open Command Window Here" from the menu. You should see a command window similar to the previous page.
Start NotePad from the command prompt:
C:Users\TEMP> notepad C:Users\TEMP>
Windows 8:
C:\Users\YourName\JavaSource>notepad C:\Users\YourName\JavaSource>
Notepad starts in its own window.
Is all this getting to be just too much?
