Jusched.exe to be exact is the Java update scheduler which checks for any Java updates once a month.
Now to me a service which is constantly running and only actually does anything once a month is a waste of system resources, around 11mb, so if you’re looking for a way disabling Java updates then read on.
(If this was a critical update it would be scheduled as a default to check more frequently than only once a month. The last Windows Java security flaw was around 2 years ago)
After disabling Java updates we can always manually check for any Java updates when needed.
To begin with launch the Control Panel and open the Java Control Panel
Once it opens select the Update tab, as you can see updates run once a month.
Un-tick Check for Updates Automatically, you will now see a Java Update Warning stating You have chosen to never check for updates and may miss future security updates.
Select Never Check and click OK to close the Java window, now the jusched service will cease to run
As with Windows XP launch Control Panel – Select Programs
Java – Select the Update tab and Un-tick Check for Updates Automatically, then you will be presented with a Java Update Warning, now select Never Check and select OK to make the change.
Once the change is made the service will automatically stop completely.
As you can see with both XP and Windows 7 the change is very straight forward and can easily be changed back re-enabling the service if ever you need to.
If you ever want to check for Java updates manually go back to the Java Control Panel and select the Update tab and then select the Update Now option.
