Are you referring to Google Chrome?

Do you have a round Red Yellow, and Green icon on your desktop for this?
Having only one web browser is not a good idea. You always need a backup, in case of errors with updates.


If you right-click on the Start button and select Run, you can enter cmd to get a Command Prompt or enter winver to run that command.

To do a reinstall, you would need some installation media, either a DVD or a flash drive set up to do this. I will post some info on how to create these later.
