So let's go back and take a quick
historical tour for where Microsoft's operating systems evolved from.
First operating system from Microsoft was a mess DOS
and the Emma's DOS system came up in 1981. It was actually a contract that Bill Gates and Microsoft had with the IBM corporation.
It was a 16 bit operating system means that ran on 16 bit processors of the day, which were like 80286 processors.
Applications directly controlled the hardware. And what that means is, if you wanted to print
in that system,
you'd actually have to write a print driver into your application.
I can still remember Word perfect at that time had three print drivers written into the application,
and that's because Word Perfect was printing directed to the printers.
So the last release of that was in 1993
and DOS 6.22
Following that was Microsoft Windows,
and the original Microsoft Windows actually wasn't an operating system. It was an operating environment,
which means there was a program that ran on top of DOS.
So when you were installing windows,
windows two windows, three windows, 311
you installed DOS first, and then you booted Windows on top of DOS,
and all Windows did was provide a graphical interface to manipulate DOS
windows for workgroups.
In November 1993 was the last version of that train of Windows, and that version was the first version that had networking where two or more computers could talk to each other.
development was the first
true from the ground up gooey operating system the Microsoft put out. And that was Microsoft. Windows 95
came out in August of 95
natively booted into Windows. There was no DOS anymore underneath,
and it was a 32 bit operating system, which meant it talk to the Pentium processors that had just come out in that era.
It was fully backward compatible with M S DOS
because most of the programs of that day were still written for DOS and you needed to have DOS compatibility
that went through 95. And then Windows 98 came out, and then Windows and me came out. And in September 2000 that was the last release DOS compatible applications dogs, compatible operating systems.
Microsoft at the same time was working on a parallel group of operating systems
called Windows and T
Windows NT was actually evolved from another IBM contract,
where IBM and built a 32 bit operating system called OS two
and Microsoft was
building that project with IBM. Microsoft spun that project off into Windows NT.
the applications access hardware through something called a hardware abstraction layer, and that's common today,
but we don't think of it because we haven't been involved in it.
What it means is, when you install a printer today,
your printer gets installed into the print application
in the operating system.
And when word or
Internet Explorer something else wants to print it prints to the print Apple case and in the operating system. So the print application the operating system
gets input from the application
makes a CAC's into the printer and passes in between
as a hardware abstraction.
That way, you can be sure that somebody who writes bad code can't crash your operating system
because they can't make a mistake in memory assignments or other things in the computer.
It also introduced the NT file system and T. F S
and NT F. S was the first
truly rugged, reliable file system that Microsoft had put out
the fat or fat 16
was a good operating system but had no security and didn't have any redundant layers in it. And then T f s does,
uh, when and he came out. One of the other things they did was they developed the first servers and the anti anti three and 94 servers where the first time there was actually a server operating system separate from a user operating system.
The last release of anti was NT 40 service packed six A in November of 1999
and shortly after that
the Windows 2000 family.
Everything we now have for Microsoft in operating systems is spun off the Windows 2000 Siri's.
They're separate workstation and server versions.
The server versions were actually scaleable.
They had more than one server version that enterprise versions as well as
smaller workgroup versions.
They had a new optic based security model and L dap my way directory access protocol, enterprise, security
for their domains.
So everything that we do today with our current operating systems all come from this Genesis,
NT and 2000 systems
I could run some DOS based applications, but they didn't guarantee it. He was running your own risk.
So this train is still current Windows 2000. The original version is no longer supported,
but Windows 2000 spun off Windows X P Windows Vista Windows seven,
which are all current operating systems and the operating systems covered by this exam.
If you look at Windows X P came on October 2001 in April 2014.
He is when Microsoft is going to suspend support for that.
Exp was a 32 bit operating system and also had a 64 bit version.
There wasn't very popular because when it came out, 64 bit systems were rare, but it did support 64 bit
came out in November 2006
32 64 bit,
and then Windows seven
is 32 bit and 64 bit with the 64 bit preferred.
So that's kind of the transition point for Microsoft, where they went from being 32 bit preferred
and 64 bit offered
to being 64 bit preferred in 32 bit offered.
Windows eight has come out since Windows seven,
the Windows X P versions,
when those x p did have a starter edition, a home addition, a professional edition, a media center edition and a tablet PC addition.
And all of them were a little bit different.
The start of addition for Windows X P.
You'll see in the other operating system. They have something similar. The Starter edition was sold in less developed countries.
foreign language support,
but it was a stripped down version of Windows. Expiate only had a limited multitasking. You could only run three concurrent applications. Once you open three windows, you couldn't open the fourth out.
He didn't support war groups, didn't support domains
and was hard were restricted in terms of the maximum CPU and memory you could use. It was a low cost version to help him get into Third World markets.
X p Home
was the version they expected most people
to use as a whole machine. That's why they named it XB home.
It didn't support domains,
but it was optimized for work group so you could share files between users
and it had no 64 bit version
it had a simplified security package, they were trying to make it look as much as possible. Like the Windows 95 Windows 98 model people had been used to and been happy with.
So simplified security Intern included things like having guessed accounts on by default,
having automatic log on on by default.
Other things like that
expert professional was what you expected to see in the business world.
It's supported. Multiple processors supported automated system recovery, which was a way to get years
X p installation
restarted if it had corrupted itself. It supported personal Web service is supported encrypting file system the F S.
It had used her mobile file security so you could now
control who could get into which files on the
and other things that made it more of a business application
on the mains inside supported remote desktop.
As a remote desktop server of meaning, you can log into the exp professional box
it supported domain membership group policies.
which was the local update service,
supported roaming profiles, enterprise installations,
the remote installation service insist ***
and basically was their first attempt to make a truly
friendly a business based system.
They did make it last two versions. Media Center Addition. Media Center Edition was Microsoft's first
venture into the media market,
and a lot of Media Center Edition actually came as appliances. You couldn't buy Media Center edition of
software. The only way you could buy it was to buy it in a pre constructed system
and then finally, x p Tablet edition
and the Tablet PC addition was essentially X p professional, upgraded with touch screen stylist, handwriting support and other things you need to be able to run a tablet
with those vista.
fall onto Windows X P
Windows. Vester was the first operating system that tried to put in
a whole new security model
called user account control. We'll talk about that in a moment
again. There started additional sold in less developed countries and had most of the same restrictions that were in the start of version of Windows XB, including a maximum of one gigabyte of ram.
This the home basic similar to X p home.
It had no arrow, and we'll talk about Arrow. Arrow is something we generally refer generally think of when we think of the glass panes that you see in Vista and in Windows seven. But era was also
a whole bunch of other changes in terms of
what happened with the keystrokes and mouse clicks. The changed
suddenly in subtle ways, changed how the operating system worked.
This the home premium
similar to X p
Media Center addition.
It did support HD TV games, tablets, 10 concurrent connections that was the highest home version of Windows Vista.
The last three versions role
for the enterprise. This to business
supported domain service's E F s
offline files. Shadow copies.
Shadow copies are really time second copies of What
on your hard Drive.
That way, if you have a crash
or if you needed to
go back for some reason and reverse your files, you could
shadow copies are actually also the system used
for on manic recovery.
So if you want to go back to an earlier installation of Windows,
you'll see it's live later on how we do that. But that's only supported because of Shadow. Copy
this to Enterprise.
It was the chance he visto business with multiple language.
Been locker was included. Bit Locker is a
Dr Level of file encryption system.
And the idea behind been locker was, If you're using a mobile device like a laptop and you lose it at the airport,
nobody else can access your files because the entire hard drive is encrypted.
This enterprise was another version of Vista. You could another version of their operating system you could not buy in the store.
It only came with the software assurance distribution. You had to buy a death in Enterprise
and in Vista, Ultimate
Waas, the best of home premium and enterprise, and it was available for purchase.
So that's the one individuals could get if they wanted to get something that was like this to Enterprise
Windows seven also had two Starter Edition
on *** computers. You could not buy Windows seven started by itself,
and it was 32 bit only and similar to Vista. Basic
Window seven. Home Basic
was restricted activation only in emerging markets.
He had unlimited support for the arrow features.
If you want full era functionality, you had to goto Windows seven Home Premium
Windows Home Premium, much like Vista Home Premium. No enterprise support. But other than that had all the features you'd expect to see
in a home user operating system
jumping up one more toe. Window seven. Professional
Much like x p professional
That was the entry level version of the operating system for
Supports Domain Support CFF Offline files. It also had something called Windows X P mode, where you could actually run essentially a
shell of Windows X p.
So the assist the excuse me so that
files and applications that wouldn't run in Window seven could be running this window's X P shell
and his support. 192 gigabytes of RAM if you're in the 64 bit version.
Windows seven Enterprise.
Windows Vista Enterprise. They added the multi language. He added the bit locker, and it was only available via software assurance, meaning you couldn't buy it in the store
when just having ultimate
similar to the enterprise.
It had Windows seven, Home Premium and Windows having professional
and can be upgraded
from Windows Home Premium or Windows seven Professional into Windows Ultimate.
So Windows Ultimate was the purchase a ble option that looked very similar to Windows Enterprise
