Sir,

Would u say the msdos command to lock the properties option in pop up menu

There is a way to lock the properties of files for other users if you are the administrator, I've never done it though.

I'll answer this question EXACTLY as it was asked.
Curlyben says "the msdos command to lock the properties option in pop up menu"

Now that's out of the way lets try and work out what you are trying to do.
What operating system are you working on ?
Which properties window do you mean, OS one or Internet explorer pop up ?

The more information you give us the better we are able to help with your issue.
