On Vista Ultimate where can I find Hardware Diagnostics Tools (which comes up automatically from time to time) so I can then change the scheduling? Thank you. Jon.

If it is the memory diagnostic tool then just type "memory" into the strart menu.

apologies I didn't read you question properly.... try end the process in the task manager... press > Ctrl + Shift + Esc click on process tab to find diag tool

Bugsy: I opened Task Manager, clicked on the "Processes" tab, but I don't see anything resembling "Hardware Diagnostic Tools." Jon

I take it this something that is pre installed on a HP computer, look under HP tools under programs in the start menu, otherwise you could always choose to uninstall it from add/remove programs.... see if it is listed there.

If it is HP then take a look here for more info on it

Bugsy: OK, I found it in the uninstall programs feature. (Yes, my computer is an HP, and Hardware Diagnostic Tools did come pre-installed. The publisher, by the way, is "PC-Doctor, Inc."). Thank you. Jon.

Ok that's great..

Maybe there is a way to disable it rather than uninstall....

Good idea. The program has a box for "Enable Scheduled Maintenance" box which I unchecked. Thanks again. Jon.

Thanks for the feed back jon could come in useful for others
