Release Regression From : 6u20
The above release value was the last known release where this 
bug was not reproducible. Since then there has been a regression.
since the above release (6u20) is the same one this is reported against, I am removing the regression keyword until any evedence is given to show there is a regression here.

                                    

Comments
EVALUATION

Many Applications can easily be uninstalled from Add/Remove programs.
We need an example of an application that can not.
The message: "Unable to completely uninstall application."
may come uf after attempted uninstallation for many reasons including locked files, or corrupted cache.  To determine what the cause is in this case, we need an example of an app that shows this behavior.

EVALUATION

I can now easily reproduce this with JDk7.
the problem occurs when the app has already been removed, but still in Add/Remove for some reason.
calling javaws to remove should return error to indicate it failed to remove, then windows will pop up window saying it couldn't completely remove it, and if user agrees, remove the entry in the add/remove list
