One of the major requirment for the Improve java update is to avoid the download in peak hours to control the download traffic in peak intervals.

Please not timings are mentioned in IST format (Where ever it is not specified).

How to Reproduce

1.) Install JRE 6u10 pit b13 respin bundle.

2.) Create the UpdateServletURL registry entry and RunAtExactSchedule (set it to 20:00).

3.) Open JCP and set the update schedule to daliy and say 8 PM.

3.) Modify the "predownload" in Version XML file. "predownload" should contains the off peak hours interval setting in GMT format. Make sure 8 PM local time (IST) does not fall under the interval. For example 8 PM IST is 2:30 GMT; set predownload to 16,23

4.) Modify the system data and time (7:52 PM).

5.) run the "jusched.exe".

Wait for the update to happen. Java Update bubble will pop up in the system tray.

Expected O/P

AU should not prompt user to install the update as current time is very much in peak hour limits.
How to reproduce?
1.) Do a silent install and try to do auto/manual update.
2.) Just make sure java soft key is there under HKEY_CURRENT_USER.
3.) Now do a silent uninstall.

You will see java soft key is there under HKEY_CURRENT_USER, is not cleaned up after silent uninstallation. Now you try to run peak hour test case, it will fail.
