This is a requirement for the automation of java auto update testcases. As of now, we can schedule update on hourly basis (10:00, 11:00 AM, 11:00 PM etc.) To automate the testcase, i should be able to run the auto update at any given time (11:05 AM or 11:55 PM). I can't change the system time, as it will impact the test setup and all the testcases may fail eventually.

We are fine with any option.
1.) From registry key
2.) Invoking the Java update thorugh command prompt
