Windows operating system features.
00:08
And these Windows features are add ons that provides service is beyond
00:12
just what the minimum operating system would have to D'oh!
00:15
Minimal operating system doesn't have to have a backup
00:18
facility, for instance,
00:20
so back up would be a feature.
00:23
As you can see, we're gonna go on one slide for each of these features so we can talk through
00:29
the specifics of each feature.
00:35
1st 1 is 32 bit versus 64 bit CPU support.
00:40
64 bit CPU Support began with Windows X P. They did have a professional x 64 addition,
00:47
uh, wasn't used much because if you think back to the 3 4000 for 2005 era,
00:55
there weren't many 64 bit platforms at that time.
01:00
Windows Vista support 60 Forbidding everything but the starter
01:03
and same with Windows seven.
01:06
Everything with the Starter edition.
01:08
So what's the difference between 32 bit and 64 bit
01:12
32 bit CP Use can only address four gigabytes of RAM.
01:18
And if you, if you did the math, it's actually a mathematical issue. There's only
01:22
two to the 32nd power address spaces
01:26
you can make.
01:29
And because it's the 232nd different addresses, you can have
01:34
that limited to four gigabytes of addressable RAM.
01:38
64 bit CP use have to to the 64th power, which is
01:42
an explanation. A larger number,
01:45
uh,
01:46
Windows
01:48
seven
01:49
can support up 292 gigabytes of RAM, and that's nowhere near the maximum. The maximum of off is up in the terabytes range.
01:57
You get a lot more
02:00
ability to use memory.
02:01
Another thing. 64 bit CPUs have more processing power than 32 bit CB use
02:07
64 B C P. Use can also run 32 bit programs for backward compatibility and even 16 bit programs.
02:16
So in terms of bang for your buck,
02:19
the world is gonna go towards 64 bit CPU support just to get around that four gig Graham ceiling.
02:28
Now the
02:30
screen capture at the bottom of the screen actually shows a 64 bit operating system.
02:35
And if you look at the
02:38
readouts on the screen, one of them says 64 bit operating system. The second line from the bottom.
02:46
And that's how you can find out what your system is and to do this who went to computer properties, and it just shows up under computer properties. So you know which version you have installed.
03:00
Administrative tools.
03:01
Administrative tools with
03:04
feature brought into Windows X P and it's been expanded, invested and expanded, beginning Window seven.
03:10
And basically, it's just a container used to support
03:15
administrative applications that run things about the host operating system.
03:22
So if you look down the list on the right hand side there, you can see Components. Service's computer Management David Service is the event you're
03:30
ice cosy. Local security performance monitor print management to get the idea. All the things we want to know about.
03:38
How are the pieces of our operating system running, and how can I configure them or change them? Were all come through administrative tools.
03:52
Arrow.
03:53
The aero system
03:54
was introduced in Windows Vester. There was no arrow in Windows X, P
04:00
and Windows X, P and all operating systems up through Windows X P
04:05
changes to the screen actually ran through the operating system and ran through the CPU
04:13
with the Aero System and Windows Vista.
04:16
They actually took all the functionality and all the animation that occurred
04:21
within the operating system on the screen
04:25
and had that processed by the screen graphics card and not by the CPU, was freed up a lot more
04:32
CPU cycles to make the rest of the computer faster.
04:36
But what he took is it took a lot stronger video card.
04:41
So to support that new gooey appearance, including Aero Glass,
04:46
it required a hardware accelerates on the graphics card.
04:49
And that's direct X nine
04:51
and a minimum of 128 megabytes of RAM.
04:56
And a lot of the better systems are running 5 12 or even a gigabyte of RAM just to support
05:01
the video card.
05:05
Been Locker
05:08
Locker is not supported in X. P is supported in certain versions of Vista and certain versions of Windows seven.
05:15
It's a full disk encryption feature to protect data at rest,
05:19
meaning
05:20
when your systems off,
05:23
everything on the drive is encrypted
05:26
with everything on the drive encrypted. Even if you lose your system, or if somebody tries to break into your system,
05:30
they can't read the data.
05:32
So when you think about um,
05:35
newspaper articles you've seen in the past where somebody loses a laptop, it at an airport and a bunch of Veterans Administration files get compromised
05:45
if you have full disk encryption, even if you lose your laptop,
05:48
the date is not lost because the data is encrypted.
05:54
Two ways to do the encryption.
05:56
If you have a trusted platform module chip, TPM tip,
06:00
then the encryption is done in hardware on a tip on the motherboard.
06:05
If you don't have t p M,
06:08
then this will still support the encryption of the desk. But you have to use manual user authentication or USB key mode because it can't be supported by a T. P M chip that doesn't exist.
06:21
In Been locker, you require a minimum of two partitions. It keeps one small partition
06:29
called the system partition unencrypted so that when the system first starts up,
06:34
it can access enough of the operating system to know what to do next.
06:40
The main OS is in an encrypted partition, and that can't be accessed, and anything on that can't be accessed until after you've put in the
06:48
encryption key
06:50
or a password. Or however you want to refer to it.
06:53
That allows the encryption to be read and the operating system to be spun up.
07:02
Control panel.
07:05
There's a classic view in the classic View
07:09
was actually the view of the operation of the control panel in Windows XB
07:15
and Windows Emmy Windows 98.
07:19
In the new operating systems they support. Also a category view. The category view is the view you're seeing on the lower right hand of the screen,
07:30
and in the category of you you don't see all the icon. Do you see
07:34
categories and the actual icon you want to use? Detained things
07:39
are all
07:41
grouped underneath those category icons.
07:45
If you see the screen on the bottom right,
07:47
the there's a bullet in front of the category.
07:51
If instead you chose icons, the category go away and you get the upper image where every icon is shown individually
08:01
as the number of icons continues to grow in control panel. The idea of going to categories was trying to simplify and Uncluttered. The screen
08:16
compatibility mode
08:18
Compatibility mode is a feature in Windows
08:22
used to support older versions of applications so that when you upgrade to a new operating system, you should still have an ability to run your old applications.
08:33
It actually modifies the parameters
08:35
that the individual acts operate in,
08:37
Um, you see the,
08:41
um
08:41
screen capture on the lower right.
08:43
We're looking at a Windows Vista screen and in the Windows Vista screen. If you have an older app that won't run in Windows, Vester won't run in Window seven.
08:54
You can actually tell it to run in Windows X P Service Pack three mode.
08:58
You can change the graphics back to 6 40
09:01
by 4 80 if you want, or 800 by 600.
09:05
You can do other limitations
09:07
to make the system appear to that app as if it were the older operating system that was originally designed to run with. And it's just a way of being able to extend the lifetime of older applications.
09:26
You can get to this by going to the application itself,
09:28
right cooking on the execute, a ble and looking
09:33
under properties
09:35
or in Windows Vista, Windows seven. You can also find it under a troubleshooting panel
09:41
in control panel. You can cook that and it'll actually scan your system for you and tell you which applications might need compatibility mode.
09:54
Easy transfer
09:56
Easy Transfer is a
10:00
downloadable app.
10:01
It supports Windows X, P Vista and Window seven,
10:07
and the concept of the easy transfer tool is
10:09
if you know anything about what, how upgrades go many times, the upgrade is actually a clean install.
10:16
So the concept of easy transfer is to be able to use an application to assist in that movement of files off the old operating system stores somewhere else, so that when you perform the upgrade,
10:31
do the clean install. You can then pull those features back,
10:37
and it moves files and settings
10:41
back to
10:41
the new clean install.
10:43
It also is the
10:46
easiest way to support moving files and settings, from the 32 bit installation to a 64 bit Windows installation.
10:52
So easy transfer supports files and settings. It does not support moving applications,
11:01
But if you have easy transfer, that's how you get around
11:05
losing everything. When you do a new install
11:15
event. Fewer
11:16
event viewer is just a way to display logs.
11:20
Even viewers a next P Vista and Window seven.
11:24
It can display local log files, or it has the option. If you go to the action, Tablet has the option to actually connect to a remote machine.
11:33
Every play display the logs of another system
11:37
event viewer in Vista and the window. Seven can also do filtering sorting
11:43
so that
11:43
if you're looking for a certain log event, you don't have to comb through the entire log to find them.
11:50
You can access it via control panel administrative tools.
11:54
Or, if you have the run window, you could just type event. VW are
12:00
an event you will open
12:07
file structures and pants.
12:13
Most people
12:16
using Windows operating systems probably have some idea of how the file structure works,
12:24
but the details of it haven't changed from X p Vista Windows seven.
12:28
And really, they haven't changed all the way back from
12:31
Windows. Find 95 Windows 98.
12:35
In many ways,
12:37
storage drives were identified by Dr Letters, and that goes all the way back to the M S DOS world
12:43
primary hard drives use one enabled See
12:46
A and B
12:48
were reserved for two floppy disks of floppy disk A and of hoppy disc be
12:54
and in many of the earlier operating systems. That's how the system were run, especially in eras. Were
13:01
computers were run just on floppy disks and didn't even have a hard drive.
13:07
So a and B
13:07
can be used today for hard drive because everything is a sign of a ll be a disc management.
13:13
The drive's do contain files and folders,
13:18
otherwise known as directories
13:20
and directories, contained files and contain other directories, which means you can nest a directory inside a directory inside the directory.
13:31
If you want to get to the text based operating system, the command line
13:37
you can type C M D. And from C M. D. You can manipulate the
13:43
files and folders using
13:46
text based input.
13:48
You can also X right quick,
13:52
onii it
13:52
screen and get to you Microsoft Explorer, which is different than Internet Explorer. But the
14:00
Microsoft Explorer is actually what displays the
14:03
files and folders, or you go to the computer icon and start displaying from the hard, drive her cell
14:11
and then open up from there.
