was working with a tech doing a system restore and just now getting back on the internet.

I was working with a tech named Logan and we were running a system restore. I was suppose to be able to rejoin him with a link he put on the computer.  Restore ran for over 4 hours  and instead of crashing the computer I let it run and after 4 hours I just went to bed to get some sleep. When I got up restore had removed all my browsers.  Until just now I could not figure out how to get back on the internet so we could complete working on the computer.  I use Chrome and every once in a while Firefox.  I remembered the tech was using Edge so did a search on the computer and found edge after I got up.  Edge did work.  I  was able to repair Chrome so am just now getting back on the computer.  I want Logan to be the one to complete what we were doing.  He had checked so many things and I don't want to have to start all over.  Is there some why to get Logan back to complete working on this computer.  

I hate UPDATEs with a passion and every time this is done, I have nothing but problems with my computer.
