Thanks for the link
Ok, so here we go:
FOR /F "tokens=1,2*" %%V IN ('bcdedit') DO SET adminTest=%%V
IF (%adminTest%)==(Access) goto noAdmin
for /F "tokens=*" %%G in ('wevtutil.exe el') DO (call :do_clear "%%G")
echo goto theEnd
echo clearing %1
wevtutil.exe cl Application /bu:C:\EventViewerBackups\Applicationbackup.evtx %1
Maybe that would work? I'll test it and see what it does.
edit: nope. I'll work with it later. Does yours clear ALL event logs, or what? I don't see anything specified after the wevtutil is called in the batch file.
