LiveUpdate causes other software to crash

LiveUpdate causes other software to extremely lag and crash, this is usually older software or software that use a lot of resources.

You can add programs under which 'silent mode' applies, but this will not stop LiveUpdates. So you will need to manually start 'silent mode' for 1 hour to 1 day. This works but if you forget this it will cause trouble.

Please help, has anyone an idea to stop these crashes. Something like giving processor and/or RAM priority(which I do not know how to do) or anything that might help.

Regards ETC.
