[wpkg-users] help: install if file does not exist

[Jacob Jarick]

Thanks for the info Rainer, I will shift to your suggestions instead of my rename.
Was my check syntax correct though ?

First of all I don't believe that renaming the exe file is the right way. In
fact it could even cause problems.
Instead I recommend just to remove the startup entry for the update sheduler:

reg delete "RUN_PATH=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /v
"SunJavaUpdateSched" /f

This removes the startup of the update scheduler.
On this occasion you might also disable the quick starter service:

net stop JavaQuickStarterService
sc config JavaQuickStarterService start= disabled

This approach works for me since quite a while.


Your rename might fail for example if jusched.exe is still running while you try
to rename it. So you should at least use taskkill to assure that it's not running.
