Linux is not Windows
An OS is not something you can arbitrarily replace with a different 'brand' and continue to do computing the same way you always have.
It's like switching from taking a train to driving a car. Both are vehicles, both are means of transport that get you from A to B – but in very different ways, requiring different skills and supporting ecosystems.
The earlier you realize this and start learning, the less confusion and frustration you will have.
