One of the files that ships with WindowTabs is “WindowTabsLoader32.exe”. There is no reason for you to ever run this program directly, nothing bad will happen, there just isn’t any reason to run it.

WindowTabsLoader32 is run by the main WindowTabs.exe when you are running on a 64 bit system. For those who care, the loader allows WindowTabs to “hook” 32bit processes running on your 64 bit OS. For example, many people run the 32bit IE7 and the loader allows WindowTabs to attach tabs to that process.
