Java has had quite a few security issues recently. Therefore, it definitely makes sense to enable the Java Updater and to install every Java update right after Oracle releases it. However, on my different Windows (64bit) boxes I could not configure the Java Updater. There was simply no „Update“ tab in the Java control panel.
I found the solution here: Missing Java update tab. Possibly due to permission problems, Java did not add the following key to the registry: HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Update\Policy\EnableJavaUpdate. After I added it (DWORD, value 1), the „Update“ tab was shown, but I was not able to save the changes I made to the update interval. The solution to this problem can be found here: Why are the Java update settings not saved in the Java control panel?. You have to start the Java control panel (javacpl.exe) as an Administrator.
To save me the pain of repeating the steps above on all my Windows machines, here is a file that can be imported directly into the Windows registry and sets the update interval to daily (9:00 AM):
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Update\Policy] "EnableJavaUpdate"=dword:00000001 "NotifyDownload"=dword:00000000 "NotifyInstall"=dword:00000001 "Frequency"=dword:0000007f "UpdateSchedule"=dword:00000009
