How to reproduce
1.) Uninstall all the previous JRE's from the m/c
2.) Install promoted b32
3.) Open the Java Control panel and goto Update tab
4.) Check the "Notify Me:" drop down box. It show's "Before Download" (More info - See attached screen shot JCP_AUPolicy_Vista_b32.jpg)
It is a regression from b31. Repeat the testcase with b31 promoted bundles. you will see the difference. (More info see the attach screen shot - JCP_AUPolicy_Vista_b31.jpg)
