Hi all

Was browsing folder properties earlier today and saw in the Security tab there are a number of 'Group/Usernames' there. My user is named Admin however I have accounts labelled as "Account Unknown S-1-5....."

SYSTEM
Admin (Me)
Account Unknown
Account Unknown
Administrators

Any idea where/what these are?

Theyll be deleted users.

Late reply, I know, but strange... never had any other users on here other than Admin?

From a previous Windows install.

You can take ownership of the folders if it bothers you.
