Reg search at specific processor usage

Question

Hey,

I was wondering is it possible to search the registry for a string containing "shutdown" but as a proccess wich takes about 20% processor power instead of the 50% i cant quite afford. Its a nasty joke going around school atm to stick a shutdown command on computer startup, was gonna see if i could do something about it.

I'm not sure what's exactly your intention. I understand that you want to search the registry, but I don't know what "but as a proccess wich takes about 20% processor power instead of the 50% i cant quite afford." means.

Youre wording is a bit convoluted in my opinion, but by the title of this thread, I'm assuming that once your CPU usage hits a certain percent out of 100%, you want to do something at that point?

You're going to want to look into WMI objects then :) There's a bunch of Processor return values in there and I think from what I can remember there is a PercentUsed value or something for CPU usage. I can't remember the name of the one though.

Im guessing the search goes faster the more cpu it takes to run and basically i want it to run but with the slowness of the computers at school i need a solution that will still allow me to work. What im looking for is a way to limit the processor usage to a certain percent.

Set the Thread priority to an appropriate value, e.g. 

Threading.Thread.CurrentThread.Priority = Threading.ThreadPriority.BelowNormal

or to ThreadPriority.Lowest

The OS will take care of the rest.
