LAtest stable release, and the latest test release. I've included... IUCTL.CAB LegitCheckControl.cab OPUC4.CAB MUWEB_SITE.CAB in the HFCABS folder and, Super-Magician's selfextracting exe (Datastore.exe) in the HFSVCPACK folder Windows update works fine, but microsoft update asks for activex controls. Should also note, I use nLite to slipstream IE7 I've tested this without slipstreaming IE7 and Microsoft Update worked. So I'm assuming IE7 requires different controls maybe?
