After installing onecare, I could not log into my system again because it was requesting password for the administrator account and I did not create any password for the account. how do I go about it?
If you did not create a password for the account, you should be able to press enter with no password to proceed. I don't know why you would be prompted to log in if you normally don't log into Windows. If rebooting again doesn't resolve this, please contact support.
