I'm thinking about downloading Chrome without getting permission from an administrator at work.
Why do you want to download chrome without any administrator permission?
I want to try Chrome on my work computer.
You should never download anything into a work computer without prior permission. Downloading any files at work without proper permission could get you fired. Just concentrate on doing the work that you get paid for.
My manager don't know what I'm doing and I thought this was personal computer. I guess I learned my lesson.
If it's your personal computer, then you can download whatever you want. However, if it is a work issued computer then you're expected to get permission to download something. If you download a file or program without talking to your administrator, you're likely to get in trouble.
