I was monitoring registry changes when installing a new app and noticed a rather large (248KB) key value had changed to:
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Security\AntiPhishing\B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F]

... plus another 3159 lines
Question is, what happens if I later restore this value, as part of reinstating other registry changes "captured" during the monitoring process. Or, what would be the effect of NOT restoring this key to this state, at the time of reinstating the other key values gleaned from the monitoring process?

I'm totally ignorant of how this antiphishing stuff operates.
