'System' process - what does it do?
I'm trying to troubleshoot an issue where system process is 95%. I've run
procXP and I thought this would tell me the actual process under the top level 'system' process but the usage is actually on the system process and not one of the processes further down the tree. What does the 'mother' system porcess actually do? Cheers, Tim |

So a lot could be hiding in that "System" item. Paul |
