ok here some new information : 
since yesterday i got this f... desktop.ini also in xp pro.
so i test around:
i make a winnt.sif with nlite.
then i copied this winnt.sif into a  pure xp pro sp2  -> works without desktop.ini
svcpack.inf from pure xp pro sp2
[Version]
Signature="$Windows NT$"
[SetupData]
CatalogSubDir="i386\hotfixes"
[ProductCatalogsToInstall]
[SetupHotfixesToRun]
now next info: (bad for wim!)
take a  pur xp pro sp2 now with driverpack and base 6.10 and the same winnt.sif -> got this f*ck desktop.ini  and also svcpack.inf was corrupt
svcpack.inf corrupt
???????????????????????????
and now i didn´t want to here anything about that this was not driverpack or base which make this silly issue! i have spend the whole week for this and i´m not really happy about this! and at the beginning i said that this issue comes from base !! 
All the time was waste for that, because i know this also at the beginning....
svcpack.inf  from test with sereby´s updatepack and driverpack -> also got this silly desktop.ini file
