Toad for Oracle Xpert - Upgrade Issues

Today I updated my Toad for Oracle Xpert to and without warning it rebooted my MS Windows 7 computer, attempted to restart all of my active programs at the time of the reboot and I ended up being locked out of my MS Active Directory environment. This seemed very odd to me and would like to know how this behavior can be avoided before I have the rest of my team perform the same upgrade.
