Dear all, 

I created a custom machine key from Toolbox and then, insert it back to Toolbox. But when I change the length of the key, its still link to original part. How to completely break that link and dissociate it from the original file? (Please see the picture for more details)

Of course I have tried “sldsetdocprop.exe” but nothing that worked.

Thank you so much for reading my post and have a good day.
