As long as it keeps being shipped pre installed with every computer - especially laptops - it will maintain dominance.

I’m considering opening a hobby computer shop and have been talking with a few possible suppliers and I instantly noticed I was in for a fun ride.

One supplier has its own laptop line. I questioned on the possibility of purchasing machines from them with no OS, as my intention is to promote Linux, and custom install machines with different distros, and I was told that is not possible as all of their come pre installed with a windows license.

When questioned if I could wipe the disks and return the licenses I was told it is not possible as the windows is shipped within a dedicated non erasable storage chip, from where the system can be reinstalled whenever necessary from the UEFI.

This is a two dime supplier on a non relevant market.
