Windows XP build 2197 is an unleaked build of Windows XP that was compiled in early 2000. It was mentioned in an IT Pro article from 13 February 2000, where Paul Thurrott claimed that build 2197 was the first internal build of Whistler and that it had gone out internally "weeks ago".[1]

The build number is mentioned in several files in the leaked Windows XP source code, including the full build tag, as well as the build tag of a later recompile from 7 January:

tools\postbuildscript\ntcrcgen.pl

# param1 src path : \\\\ntrelic2\\release\usa\2197.x86fre.main.000106-2102
# param1 src path : \\ntbuilds\\release\main\usa\2197\x86fre
# param2 dst path : \\\\scratch\\scratch\\crc$
# return logfilename : \\\\scratch\\scratch\\crc\\crc_usa_2197_x86_fre.log

tools\postbuildscript\copyscript.cmd

REM assume %BuildName% = 2197.x86fre.main.000107-1856
REM assume %CopyDir% = Symbols.pri or whatever
REM assume %BuildShare% = \\ntbldtest01\release\2197.x86fre.main.000107-1856
REM assume %ReleasePath% = D:\release\usa\2197.x86fre.main.000107-1856

A script file possibly related to Windows Update, which was found in the 2022 Microsoft source code leak, also checks whether the build number is 2197 or above:

ntdev\ntdev\wu_whistler.vbs

'
' If BuildNumber is > 2196 we are looking at Whistler
'

 If (BldNum > 2196) Then
  WSHShell.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\SecurityServer", "http://fear/v3site/test/cdm_whi/"
  WSHShell.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\URL", "http://fear/v3site/test/"
  WSHShell.Regwrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\ContentServer", "http://fear/v3site/test"
  WSHShell.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent\Post Platform\Whistler32", "'""'"
 End If
