command prompt here

Adding a command prompt to the context menu got by right-clicking a folder in Windows Explorer: followed this link and added a Command Prompt item in Tools -> Folder Options -> Files Tab -> File Folder -> Advanced -> New with cmd.exe as the executable. The link actually mentions the item Folder, I did it for File Folder. Maybe due to this, CKRename became the default action for folders on double-clicking, just like this query on Experts-Exchange. Downloaded and ran the vbs file as mentioned there, restored to "Open" default action. The code in the vbs file is:
