I recently replaced my windows 7 OS with Kubuntu 18.04 LTS

I originally was doing a dual boot type of setup but windows 7 crashed strange bug where I was locked out of my user and had to reinstall windows but somehow I did not know the serial number and being unwilling to get a no license for ancient windows software, I just said I had enough issues with windows and was going to permanently rid said issues and I have been liking the new Linux experience. I got a virtualbox vm of windows 10 just in case if I need to use windows.
