Since Windows Defender is removed, you are vulnerable.

This can shrink a 20GB install to ~12GB.

Microsoft officially ships , but these builds are far from lightweight. They include the same telemetry, UWP apps, and background processes as their x86 counterparts—often running slower on ARM due to emulation layers for x86 apps.

Use tools like Rufus or Windows on Raspberry (WoR) imager to flash the ISO directly onto an SD card or external SSD.

Background data collection and tracking services are stripped out, improving both user privacy and system performance. Use Cases for Tiny10 ARM64

Tiny11 is the direct successor and has a dedicated ARM64 version that is much easier to find and install on devices like Apple M1/M2/M3 VMs, Raspberry Pi, or Surface Pro X. : Official Tiny11 for Arm64 on Archive.org

You are an enthusiast experimenting with a Raspberry Pi, want to run a specific lightweight Windows app on ARM hardware, or need a minimal VM for testing. Skip it if:

Running tiny10 (or a debloated Windows 10 ARM) on low-end ARM hardware yields surprising results:

Standard Windows 10 on ARM often struggles on older or low-tier processors due to high RAM usage and background processes. Tiny10 ARM64 solves this problem by drastically reducing the operating system's footprint, making it ideal for hobbyists, developers, and users reviving old hardware. What Makes Tiny10 ARM64 Different? Minimal System Footprint

: Most Tiny10 builds are based on Windows 10 Enterprise LTSC (Long-Term Servicing Channel), which is inherently more stable and lacks the consumer-facing bloat of Home or Pro editions.

If you want, I can:

If you are running Windows on a Raspberry Pi, every megabyte of RAM matters. Tiny10 is widely considered the gold standard for this niche.
