For "small updates", if you want to use the PatchFamily/@Version sequence to exclude older patches from the same family set the Supersede attribute to "yes" in QFE2. This will cause QFE2 to replace all previous patches in the same family (including QFE1).

Subject: [WiX-users] recommended way to uninstall previous small updates Hi, I am using windows update to release the small updates (QFEs) after V1 RTM. Suppose I have QFE1 (released earlier) and QFE2 (released later). QFE1 should be uninstalled before QFE2 is installed so that any new QFE can use the RTM image as base. What is the recommended way to uninstall QFE1? Should I add a custom action in QFE2 to detect and uninstall previous QFEs? Or I don't need to do anything and windows installer is smart enough to uninstall QFE1 before it installs QFE2? Or I can author some pre-processing commands in windows update to detect and uninstall QFE1, then install QFE2? Appreciate your guidance.
