I think somebody may have entered passwords

I am a resident of an assisted living facility. I have some computer knowledge and was asked by the director if I would take care of their new computer.
The first thing I did was create an admin account for myself and password protect it. I didn't have time to setup all of the rules to prevent any resident from getting into areas they know nothing about.
This morning I went to work on the computer and even before i got there I was stopped by two people asking me for the PW to use IE. I went in and found that a PW was required to open IE. It was OK two days ago. Then I tried to open my admin account and my password would not work. I have been using it for a week now so I know what it is.
Is there any way for me to change the admin account password or/and remove the IE PW?

Never heard of needing a password for internet explorer. It sounds like you can get into the machine OK, if that`s the case, then just create another admin account.

You should be able to change the password on your old account using the new account.

If the old password still doesn`t work, then just delete the old account.

Take a look here

Inside IE
Tools
Internet options
Left click on Security tab
Left click on Custom level
Scroll down to User Authentication
Under Logon, select Automatic logon with current user name and password

I think the problem was being on the "guest" network account instae of the "main: account.
Whwn I changed it back several of the programs that required a password worked OK. I'll check the rest out tomorrow Don't know why it was on the "guest" account.

I would also do some security scans to see if anything got installed that could cause the accounts to change.

That was the problem. Everything seems OK now.

If you`re good, you can mark the thread solved. :)
