I'm trying to configure an old XP Pro SP1a CD to include SP3 but any changes I make using nLite seems to cause problems when installing under Oracle's Virtualbox. Specifically I cannot install the Guest Extensions. If I use a later CD that already has SP3 included, the Extensions will install. I don't know if this is specific to the old XP CD, but the problem seems to be registry specific. I tried all sorts of customizing including just adding SP3, any thoughts: I've attached my latest ini configuration... LAST SESSION.INI
