Thank You So Very Much For Your Response.
Sorry that I'm not explaining my issue very well --
I don't suspect my repair technician of putting anything harmful in my files.
Sorry I made my initial question sound like I suspected technician.
The repair tech is a great guy & has good reputation.
So, let me try at explaining again:
1). When I got my computer back from technician, I have 2 ACCOUNTS:
A). Administrator Account
B). User Account
2). Both Accounts are duplicates of eac other: All my work files that are in my Administrator Account are the exact same files in my User Account.
3). When I add work / files to my Administrator Account, the exact same work / file duplicates itself in the User Account & Visa-A-Versa.
4). If I DELETE a file / document from my Administrator account, the exact same replicated file / document / Work IS DELETED in the User Account & Visa-A-Versa.
5). If I create a New User Account, it's a duplicate of the Administrator Account with all the same files.
6). Before crash & As Always: I keep my Administrator Account clean & perform my work in a specific User Account but with my current duplication / replication issue --- All Accounts : Administrator & All newly created & the One older existing User Account are mirror images of each other & duplicate all addition & deletions that I perform in a Specific Account (Administrator and/or Users) --- does not matter which account I'm working in --- whatever I do in one account is replucated in the other accounts.
7). I feel I need to turn something off in the Administrator account in order to stop the duplucations but I don't know what it is I need to turn off.
So, because of the duplications, it is useless to have User Accounts. I cannot have a User Account that does not duplicate the existing Accounts -- and if I delete something in ANY account --- the deletion is performed in ALL accounts.
I hope I've explained OK. I deeply appreciate all help.
