The Forgetten Edition of Windows XP: Windows FLP

Posted 29 June 2026

Can you believe Windows XP is, like, 25 years old? It's kinda wild, honestly. I mean, this relic of my childhood is almost as old as I am! (It's older than my sister!) Wild. But there were plenty of versions of it that you might not be familiar with. I'm not going to make individual posts for each and every one, but let's just mention a few here.

For instance, did you know that not only was there a 64-bit version of Windows XP, but there were actually TWO! Yep, there were versions for both AMD64 and Itanium! It was also the only workstation version of Windows on Itanium! (Neither Windows 2000, nor Windows Vista onwards were available on Itanium, even though Windows Server 2008 and 2008 R2 both were.) There were, of course, the tablet PC and media center editions. There were also a number of versions for low-end PCs. Windows XP Starter Edition was a version made for low-end PCs sold in developing nations. You probably knew about Windows XP Embedded, but there were also two spin-offs. One, Windows Embedded POSReady was a version for point-of-sale terminals. The other, the subject of today's post, is Windows Fundamentals for Legacy PCs.

The year is 2006. You own a business with a sizeable number of PCs designed for things like Windows 98 or Windows NT 4. Unfortunately for you, support for those operating systems is soon to end. So, what do you do with all those computers? Well, if you happened to be a Microsoft Software Assurance customer, they had the answer for you: just install Windows FLP on them!

Yeah, you may not know it from how they act now, but there was once a time where Microsoft actually cared about not unnecessarily deprecating perfectly good computers (or, at least, they pretended to care)! Yes, far from today's Microsoft telling businesses to replace all their computers or pay ungodly amounts of money to put it off for a few years, back then, Microsoft, just for being a Software Assurance customer (which got you other benefits, including free upgrades to newer versions of Microsoft software, as well as enterprise editions of Windows among other things), gave you an operating system to keep your old PCs going. (Not only keep them going, but, perhaps to Microsoft's surprise, keep them going for another 8 years, given XP's 2014 EOL.)

Windows FLP is, as mentioned, a derivative of Windows XP Embedded. Ostensibly, it was meant for lower-end PC. Legacy PCs, specifically, as the name implies. Interestingly, though, the system requirements, or the ones I can find, anyways, are near identical to those for Windows XP. Like, compare the two:

Component Windows XP Windows FLP
CPU Pentium or newer, 233 MHz Pentium or newer, 233 MHz
RAM 64 MB minimum 64 MB minimum
Storage 1.5 GB plus about 3.3 GB for Service Packs 1 through 3 610 MB minimum, 1 GB recommended
Monitor SVGA (800x600) SVGA (800x600)

The only real improvement here is in storage requirements, being able to run off of a much smaller hard drive. Otherwise, they're identical! The Wikipedia article claims it's faster on slower processors, but that also has a citation needed tag on it and I can hardly claim to have appropriate hardware to test such claims. Regardless of requirements, Microsoft sold it as being for older PCs nonetheless. From the Microsoft page for Windows FLP:

Older computers are expensive to maintain, but it isn't always financially feasible to buy new hardware for a department or your entire business.

Windows Fundamentals for Legacy PCs is based on the Windows XP Embedded Service Pack 2 (SP2) operating system. By implementing it, you upgrade to the security and stability of the Windows XP platform. You also ease the transition to the Windows Vista Enterprise operating system when you eventually replace your desktop PCs.

It's worth mentioning that this could only be obtained as a volume license for Microsoft Software Assurance customers. There were no retail or OEM licences available. As such, you won't find any computers designed to run it. It was purely intended as a solution for keeping older computers in service.

So, enough about what it is and what it was intended to run on. What's it like? Well, I'm glad you asked! What say I walk you through what it's like to install and use this? The installation process is actually kinda interesting. Unlike Windows XP, which splits its install between text-mode and a GUI, FLP goes straight into a graphical installer. After assuring Microsoft that we totally have a license to use this software, we get met with a screen asking us how we want to install it. See, as this was designed for corporations with a large amount of computers, you probably don't want to spend your time manually installing it on each and every one of them. Windows FLP makes it rather simple to get an unattended installation going. You can either install it normally once and generate a file from that (though you have to mess around with the command line on the install disk to do so) or use a sample file included in a help file on the disk and customize that. We're gonna go through the full thing, though.

Windows FLP installer Welcome Screen. It's a full graphical installer.
Yep, no text mode here. Straight to the GUI.
The license agreement in the FLP installer just says you have to have a volume license agreement and your usage of FLP is subject to that.
Shh! No one tell Microsoft!
Wizard mode. It lets you install in either interactive or unattended mode or connect to a remote desktop session.
Heh, I'd like to see you use remote desktop from a normal XP installer!

This is a volume license edition of an old version of Windows, so our product key is a volume license key, of course and, thankfully, it doesn't actually need to connect to a server to activate. Isn't that just convenient?! After we choose regional settings, we get to choose how much we want. On the small end, you'd just use it as a remote desktop thin client. If you want to use the computer for something, you're actually going to connect to a server to do that thing. But, you can certainly add stuff. In addition to Internet Explorer (which is surprisingly optional here), you can get support for various languages, local management tools, drivers, and even Windows Media Player, DirectX, and Windows Messenger. Why a corporation would need Windows Messenger is beyond me, but hey. (Did any corporations use it for internal communications?)

The product key entry screen from the Windows FLP installer. The key is apparently on a yellow sticker in the CD folder. Interesting.
I'd share the product key, but I'd rather Microsoft not attack me for sharing a product key for a 20-year-old version of a 25-year-old OS.
Your options for stuff are minimal, typical, full, or custom configuration. Minimum is the desktop and remote desktop. Typical adds Internet Explorer. Full has everything.
Components include Additional Driver Support, Internet Explorer, Language Support including Complex and East Asian Languages, Local Management Support, Windows Help Files, Windows Media Player, and Windows Messenger. We're installing everything.
Yeah, Windows Media Player and Messenger. And yet it doesn't have paint... Oops! Spoiler!

Since there's no text-mode stuff, partitioning and formatting is done with a graphical interface. Pretty cool that you can choose the volume label and drive letter while you're here.

Partition screen. It lists drives and partitions, plus lets you create new partitions.
Format partition screen. You can choose file system (FAT32 or NTFS), allocation unit size, volume label, drive letter, whether to quick format, and whether you want compression if you're using NTFS.
That's actually a pretty nice set of options. XP Embedded and its derivatives are the only versions of Windows that give you all this, as far as I'm aware.

Per usual for Windows XP installs, we need to tell it our name and (optionally) organization, then we give the computer a name (I love those randomly generated names) and admin password. Once we set up our network settings and choose our workgroup or domain, it'll confirm all the options then get to installing!

Computer name and admin password screen. The generated name is a string of random letters and numbers.
Don't you just think A08M9LJRGSQ5UW is just the catchiest name for a computer?
Finalizing setup screen. It lists what you selected for all the various options.
This is a pretty nice screen, honestly. I wish they'd kept it around.
The installing screen has a little progress bar to the side, a list of what it needs to do, the FLP logo, and some informational text.

Once we reboot and get a loading screen unchanged from the normal XP one, we go through the first boot agent then, eventually, get to the login screen. At least they decided to change the logo here, I guess.

First Boot Agent. A lone dialog box with a progress bar. It's currently installing PNP devices.
Not gonna lie, this screen was probably the weirdest part for me the first time I used FLP.
Loading screen. It's the normal XP loading screen, down to the logo.
For all you know, this is just taken from a Windows XP install. (Trust me, it's not.)
Windows XP login screen. The enterprise one, not the welcome screen. It's got a Windows FLP banner and is asking you to press control alt delete.
At least they changed this so you know I'm not lying.

The first time we get to the desktop, the colour depth is set low for some reason. I'm not sure if it's related to running it on Virtualbox. It's been years since I last tried it on real hardware, so I really don't know. But we do get some lovely low colour depth icons, including the Windows 2000 recycle bin. How nice. And if we look in the programs menu, it's remarkably barren compared to Windows XP. When they say "stripped-down", they mean it. And, nope. No bliss to be found here. But at least we can turn up the colour depth.

The Windows XP desktop but the start menu is smaller, has fewer buttons to the side, and there is no wallpaper, just blue. Also, the icons have only a few colours.
Look at them colours. Beautiful. And before you ask, yes, they at least included the nice startup noise.
All programs. There's Internet Explorer, Remote Assistance, Windows Media Player, and Windows Messenger. Two folders. Startup is empty. Accessories has the normal accessibility and communications options, reduced entertainment and system tools and only has calculator, command prompt, notepad, explorer, and wordpad for programs.
Not even paint survived the culling. How sad. Can we get an F in chat for paint?
Windows XP background selector. There are no included wallpapers.
I said it once, I'll say it again. No bliss to be found here.
The desktop and start menu again, but I turned up the colour depth.
Ah, isn't that better?

In terms of what we have, it included Internet Explorer 6. Yep, that was the newest version at the time it was released. Microsoft really was kinda pathetic when it came to web browsers at this time. Thank fuck Mozilla came along, am I right? We did, however, get Windows Media Player 10! Personally, I'm more of a WMP 9 fan, but I guess 10 is okay. And Windows Messenger 4.7. Isn't that lovely?

Internet Explorer 6 and its about screen. This version is 6.0.2900 specifically.
Yep. This was the best they could do. You could update to 7 and 8 later, but this was what was available at the time.
Windows Media Player 10 on the library screen.
Tell me this is better than Windows Media Player 9. I fucking dare you.
Windows Messenger 4.7.3001 and its about screen.
What business needed this?

In case you were curious, it includes all the normal control panel options. It also includes the Welcome Screen. I assume it's only there because it wouldn't be trivial to remove it.

The Windows FLP classic control panel. It's identical to the Windows XP one.
I think everything's there. I dunno. Feel free to call me out if I'm wrong.
The Windows FLP welcome screen. It's identical to the XP one down to the logo.
Yeah, they replaced the logo for the other login screen, but not the welcome screen. Oops.

Finally, if you want to see it doing something useful, here's Word 2003! So, if you need to do your standard office-ing, you can certainly do it on here. Perfect for the accountants in your building!

Word 2003 running on Windows FLP. Pretty basic stuff.
Is it possible? Yeah. Would you want to? Well...Maybe? I guess it depends on the computer how nice it is.

And that's Windows Fundamentals for Legacy PCs. Or should I say... FUN-damentals?! Get it? Get it? Okay, I'll show myself out now.

But, first, some closing remarks. In case you were curious, this wouldn't be Microsoft's last attempts at this kinda thing. Later on, they'd release Windows Thin PC, a similar thing but for Windows 7. It was kinda like an enterprise version of Windows 7 Starter, but less shite. Maybe I'll cover it someday. For now, I'll end off here. Maybe I'll come back and cover some of the others I mentioned at the start. Certainly not in this level of detail, but still. So, yeah. In the meantime, hopefully, you've learned something interesting. Have a nice evening (or whatever time of day it is for you)!
