Microsoft allows you create a second "login only" account username to access your e-mail and other services. I was having the same problem as you but much worse. Check into it, only takes a few minutes to setup.
It's a very common security technique to avoid being targeted by malware. I believe even the Microsoft KSLDriver drops randomly named DLL and device drivers along with creating a randomly named system service. Uses 8 hex characters.
Several third-party vendors use the same technique, mostly security vendors.
