A guy called "True Orient" helped me with a bit of this info.
C:\Program Files\Common Files\Real\Update_OB\realsched.exe
heres a bit more:
Real Networks Scheduler which gets installed with RealOne Player. Under Win9x/ME this task shows as TKBELLEXE, and as EVNTSVC under Windows 2000/XP or REALSCHED depending on which version of RealOne Player you have installed. From our experience, everything that applies to EVNTSVC below, also applies to REALSCHED. RNDAL is a good starting point to read about RealOne Player. Next, a 15-Jun-2002 extract from the RealOne Player License Agreement that is specific to EVNTSVC (the said License Agreement was updated on 25-Nov-2002 by Real Networks and EVNTSVC was replaced by REALSCHED in that version of the License Agreement) : An application Scheduler, known as “evntsvc.exe,” is installed along with RealOne Player. Once installed, it runs independently of RealOne Player. The Scheduler does not collect personal information or communicate with RealNetworks’ servers. It is used to remind AutoUpdate and Message Center to perform their tasks at pre-scheduled intervals. The Scheduler is also used to automatically launch RealNetworks’ Media Type Helper. The Media Type Helper ensures the system is configured for correct operation of the RealOne Player with Multi-Purpose Internet Mail Extensions (“MIME”) types, file extensions, Internet protocols and other media types. If a media type has been assigned a different action by a different application, Media Type Helper may override the association and substitute its own association.
If reading about RNDAL did not put you off, then read on. RealPlayer Classic used to be one of the most needed pieces of software on a PC. Its successor, RealOne Player, is vying for the title of the most hated piece of software. For a start, on many PCs EVNTSVC/REALSCHED slows down boot-ups unacceptably, using up to 90% of CPU time at times. There have also been reports of EVNTSVC dropping advertising shortcuts onto the desktop during idle times. Next, if you try to disable EVNTSVC/REALSCHED on the Startups tab, RealOne Player checks to see if it has been deleted or disabled in the Registry and re-instates it as an enabled startup item ! To be fair, there is a facility within RealOne Player to “only perform automatic services while RealOne Player is in use”. However, since RealOne Player is unfortunately needed to watch videos on many news sites.
is that convincing? if anyone wants to know how to remove it say so, real operates fine without it.
