Tried to slipstream a copy of my Win XP SP1 on Harddisk first with nlite, then with the manual command:
WindowsXP-KB936929-SP3-x86... /integrate:H:\xpsp1

The result is a frozen PC that has to be restartet by the reset switch.

In a virtual driven (VirtualBox) XP without ZA, everything worked fine.

Back on the main PC, slipstreaming worked fine after I stopped ZA ISS

Anybody got the same symptom ?
