thank you so much for y'all's help! greatly appreciated! Will Definitely try it and modify it if necessary! Thanks Again!! 

You can't update java without disrupting users unfortunately.  I'm using a modified script from John Verbosk that will uninstall all v7 Java versions and install the newest 7u15.

taskkill /F /IM iexplorer.exe
taskkill /F /IM iexplore.exe
taskkill /F /IM firefox.exe
taskkill /F /IM chrome.exe
taskkill /F /IM javaw.exe
taskkill /F /IM jqs.exe
taskkill /F /IM jusched.exe
MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F86417002FF} /qn
MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F83217007FF} /qn

MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F83217013FF} /qn
taskkill /F /IM iexplorer.exe
taskkill /F /IM iexplore.exe
taskkill /F /IM firefox.exe
taskkill /F /IM chrome.exe
taskkill /F /IM javaw.exe
taskkill /F /IM jqs.exe
taskkill /F /IM jusched.exe
msiexec.exe /i jre1.7.0_15.msi /qn

I set this up to run when the user is logged off only at any time.  It will kill all programs remove any version of 7 and then install 7u15 quietly with no gui.

You just need to create a batch file and zip it up with the msi and cab file and create the managed install to run the batch file from within the zip.
