[Autogenerated] let's see what that looks like in tools let's start
with task manager with task manager in the processors view we can
right click in the columns area and look for the base priority
property here or the column.
So here it is.
Let me also add the threads count here and so you can see that
we have the base priority which is one of these six values
we've seen in the previous video.
If I right click,
we can even change the base parity of the process by
selecting one of these six possible values.
So this correspond to the numbers we've seen in the
previous slide which would be 468, 10, 13 And 24.
The number is not shown, not shown by task manager.
Once we do that,
the change is immediate and and then this process that
contains a bunch of threats might get more CPU time if I
increase the base priority in some way.
And of course we can lower the base priority as well in order to get
to the real time range will have to run the particular process that
mean privileges but it's definitely something we can do if we haven't
mean privileges on the machine.
So here we can see the base priority.
In fact we can see that most processes have a best priority of normal,
which is like I said,
the default and this is all we can see in task manager
really to get some more insight, we need to look at process explorer.
So here's the process explorer tool.
In fact,
that's the new version version 17 that came out and not
long ago before I made this recording.
In fact I worked on some of the aspects of these tools you can see here,
there's the threads view here at the bottom that shows all the
properties over threats in a very easy to see view without the
need to double click a process and go to the threads tab and of
course that tab still exists.
So one of the things that we see here, which we've seen also in the old view,
let me grab the old view just first just to make sure we we
kind of correlate what we've seen in the past.
So here's the old view, we can see every thread,
you can see some of them the properties here in the
list but to see the priorities,
we actually have to look here at the bottom and for each thread we can
see the based priority and the dynamic priority.
The priority is the one that is being used right now because this is really
based on some boots that might be currently active in this case,
this particular threat has the boost of plus two,
which is very common for UI threats while they're waiting for messages.
And the idea here is that once a message is received,
it's it's better to have the threat perhaps have a higher chance
of getting CPU time sooner rather than later in order to process
that UI message in other threats.
You can see that the bass pro economic priority are the same,
which means this spread country has no boost associated with it.
So anything could really happen here.
And the booths are also just to note their temporary,
the temporary and at some point their decay back.
This really depends on the type of boost or the reason the boost was applied.
Looking here in this view here,
we can even start here by based priority if we so desire.
We can sort by dynamic priority for a particular
process of interest in this case.
That's an explorer process which as most Processes have a lot of threats.
So you can see some of the threats running priority 15
which is the highest in the normal range and explore does
have a base priority of normal.
We can see that by right clicking and using select columns here are going to
process performance and here we can get the base priority here,
which is essentially the same thing that we see in task manager.
Well almost it's actually translated to a number here and if I right click
there's an option to change the base priority or the priority class of the
process as you can see here by selecting appropriate value here and
process is nice enough to show the actual values that are associated with
the priority class itself.
There's another thing here called background,
which I'll explain later in this module.
So you can see the priorities here in the actual priority that is in
effect right now is the one that is in the dynamic one.
So the dynamic one is the one that actually is the determining factor,
so it's not the base, it's dynamic one,
including any kind of boost that that particular threat may have received.
