Based on the earliest Win10 architecture.
Creating your own Lite ISO is a rewarding technical project, but it should be treated as a tool for offline or air-gapped systems, not as a daily driver for a PC connected to the internet. Always prioritize security and stability over the pursuit of "lightness." windows 10 1507 lite
The creator hadn't just removed the bloatware (Candy Crush, Weather apps). They had removed the slack .
