History
[
]
Windows Fundamentals for Legacy PCs was originally announced with the
"
" on 12 May 2005.
("
" was announced as a potential
follow-up project at about the same time.
) The name "Windows Fundamentals
for Legacy PCs" appeared in a press release in September 2005, when it was
introduced as "formerly code-named 'Eiger
'
" and described as "an exclusive
benefit to SA [
] customers".
A
evaluation from April 2006 stated that:
The main purpose of Windows Fundamentals for Legacy PCs (WinFLP) is
to allow users running old PCs to be able to replace unsupported
Windows NT Workstation v.4, Windows 95 and Windows 98 with a
supported release of Windows XP (or, eventually, a version based on
Windows Vista). [...] Because WinFLP will have the ability to run some
applications locally – including Internet Explorer, media players,
Instant-Messaging clients, Java Virtual Machines, terminal emulators
and ICA or Remote Desktop Protocol clients, and Microsoft Office –
WinFLP can be better described as a "lean client" than a "thin
client".
— Gartner
The
version of Windows Fundamentals for Legacy PCs, which was released on
July 8, 2006, was built from the Windows XP Embedded Service Pack 2
codebase.
The release was announced to the press on July 12, 2006.
Because Windows Fundamentals for Legacy PCs comes from a codebase of Windows
XP Embedded, its service packs are also developed separately.
For the same
reason, Service Pack 3 for Windows Fundamentals for Legacy PCs, released on
October 7, 2008, is the same as Service Pack 3 for 32-bit (x86) editions of
Windows XP.
In fact, due to the earlier release date of the 32-bit version,
many of the key features introduced by Service Pack 2 for 32-bit (x86)
editions of Windows XP were already present in the RTM version of Windows
Fundamentals for Legacy PCs.
Service Pack 3 is the last released service
pack for Windows Fundamentals for Legacy PCs.
In May 2011, Microsoft announced
as the successor product.
