How I set an MSI to leave behind a major registry key on uninstall?
I have an app which writes a registry key (HKLM\Software\Mitchell) on install and then writes registry keys below that. The problem is that we have apps from the same vendor and all of their registry keys are written unser the same registry key. When I uninstall this one app, it deletes the entire major key of HKLM\Software\Mitchell, removing the keys for the other apps.

Its better if you move those registry keys into new component and mark it as permanent(set its attribute to 16).

Make the componemt holding the registry keys a parmanent componet from Wise or InstallShield or whatever you are using. Then when you uninstall all the other registry, files etc etc will get deleted but whatever is in this componemt will stay in the system.
