Why did they use only the switches /q /n /z for WinXP SP2 patches at the beginning of this topic? I ask this because if I start one of these patches with the /? switch, I'll get a popup box with (really all?) available ones and there e.g. /silent or /quiet are shown and not the /q /n /z variant (which is already used by the svcpack.inf after using the /integrate switch). Can I use both variants and are they the same?
