Javascript PC Emulator - Windows 10 (Legacy x86_64)
This page allows you to run a full Microsoft Windows 10 (Build 19045, "22H2") operating system directly in your browser.
It uses the TinyEMU x86-64 dynamic translator compiled to WebAssembly 4.0 (WASM-GC).
Profile:
Starting Windows...
[JSLinux] Ready.
Type: Windows 10 (2015-2025 Era)
Kernel: NT 10.0 (Emulated)
Image Size: 4.2 GB (Compressed via LZ-7)
Press "Click to Start" to boot.
Technical Notes
Performance: On a modern RISC-V or ARM64 desktop, boot time is approximately 1.5 seconds.
Legacy x86 hosts may experience "sluggish" cursor movement due to translation overhead.
Storage: The filesystem is mapped to a transient Origin Private File System (OPFS). Any changes made to the Registry or C:\Users will be lost upon closing the tab.
Compatibility: This emulates a "vintage" PC setup (Intel Core i7-8700k equivalent). TPM 2.0 is emulated in software to satisfy Windows 11 upgrade checks, though upgrading is not recommended due to bloat.
Privacy: The "Telemetry" and "Cortana" services have been null-routed at the emulator network stack level to prevent historical data leakage.
News
2034-02-14: Added support for Windows 10. While considered "retro" software, it provides a useful environment for running legacy 32-bit applications that fail on Windows 15. 2033-11-05: Optimized the JIT compiler. Windows XP now boots in under 12ms.
