Customization Limited (Settings) High (Kernel to UI)
Security Good but targeted Strong permission model
Usage Desktop, Gaming, Corp Servers, Cloud, Dev

2. Cost Models

Windows (Commercial)

Developed by Microsoft. Costs money because:

  • Proprietary, Closed-Source
  • R&D, Support, Updates included

Note: When you buy a laptop, the Windows license cost is included in the price.

🛠️

Linux = DIY Workstation

Requires learning, full control, powerful. Best for technical builders.

7. Summary & Decision

Choose Windows if you need commercial software (Adobe, Office), user-friendly GUI, or are a gamer.

Choose Linux for servers, automation, development, high security, and performance efficiency.
