There are times when I do need windows. That is why I kept the default install on my laptop and put Linux on dual boot.
In this case, my son wants to play bedrock Minecraft, and eventually I’m sure he will want to play games that don’t work on Linux.
For recent examples of why I need to have it around just in case, I’m interviewing for jobs and 90% of them use Teams. It took me a few weeks to get a solution to work on Linux.
