Install 6u10 b27 6/19 PIT JRE on Vista.
I installed jre-6u10-windows-i586-p-iftw.exe on new-mexico.

Uninstall 6u10 JRE.
After the are you sure you want to uninstall this product prompt,
the UAC dialog, "An unidentified program wants access to your computer" is displayed.

See attached.

Expected Best case: no UAC dialog is displayed during uninstall of JRE.
Better than current behavior: Sun Microsystems be identified as the publisher and better description than "Update" for something that wants to run during uninstall.
