how do stop work viewing my private files when they remotely log on to give me it support

If it is your personally owned computer, do not let them connect to it.

If it is a company owned computer, don't store any personal files on it.

If it is a company owned computer, the company owns ALL of the data on it. Nothing on it belongs to you.

When IT logs onto your computer for support, they alreayd have admin privileges that allow them to see anything they wish, and there is no hiding from admin privileges. Othewise, what has already been said here by others.

The other responses do, accurately, state the official line. However, for the sake of reality:

Store your private files on an external drive and disconnect that whenever anyone other than yourself is accessing the system.

Note that, technically, and depending on configuration, admins in your company's support organization may have the ability to log into your machine at any time, whether or not you know it.

Also, for completeness, please tell you you are asking because your company's internal support is working on your system, and not because you received a phone call from "apple support", or "Microsoft support" saying that your machine is infected with a virus and that they need to clean it up.

Hello,

Perhaps do not store your own personal private files on a work owned computer?
