difference between wuauclt1.exe and wuauclt.exe


what difference between wuauclt1.exe , wuauclt.exe files ( under system32 folder ) ?

in of cases, windows update service is not working client machines having these 2 files.

even tried delete wuauclt1.exe, created automatically.

what difference between wuauclt1.exe , wuauclt.exe files ( under system32 folder ) ?

the wuauclt1.exe (and sister file wuaueng1.dll) components of legacy au agent shipped operating systems released prior 2005. (the wuagent v5.8 shipped wsus v2 in spring, 2005.)

checking file version of file on windows xp system shows 5.4.3790.5512, dated 4/14/2008. additional quirk surrounds particular version -- comes installation of windows xp service pack 3. on windows server 2003 or windows 2000 system, may have earlier version number , date.
