What would access a guest account?

[Gary]

I recently ran Belarc Advisor to verify some computer internals and saw that
my guest account had a last login from two days prior. The guest account
was never used and it was still set to off in User Accounts. Would a
download or some MS update use that account to access the system? (Vista
Home Basic SP1 with all updates).

Do you have any shared folders accessed from other computers on the network?

 

[Gary]

No. All options in Sharing and Discovery are set to off in the Network and
Sharing Center.

No, and if you want to find out what is happening on the system with
things such as login and other such events, then you should enable
Auditing on Vista and review events in Security event log.
