Future Windows on ARM could be as bad as android smartphones are today with locked down boot-loaders and unsupported driver chipsets. God help you if your windows ARM chip is a Qualcomm one. You’ll never be able to update your pc after 3 years or install an an alternate OS on it. ARM is also owned only by a single company the x86 instruction set is owned by two companies ( intel and amd ) intel and amd would rather develop an open source RISC-V architecture then pay constant licensing fees to ARM
