A standard Windows 10 ISO is between 3.5 GB and 5.8 GB .

Pure malware. Never run unknown executables from untrusted sources.

| Version | Approximate ISO Size | Description | |---------|---------------------|-------------| | | 2.5 – 3 GB | Removes Windows Update, Edge, Cortana, many drivers, and UWP apps. Still includes core GUI. | | Windows 10 Lite (modded) | 1.8 – 2.2 GB | Extensive component removal; no Defender, no Store, no printing support. | | Windows 10 PE (Live CD) | 500 – 800 MB | Runs from RAM; all changes lost on reboot. Good for recovery, not daily work. | | Windows 10 Command Line only | ~300 MB | No GUI at all; for embedded systems or extreme tinkering. |
