Release status
ZeroWrite 1.0 is in early access. Builds are published to GitHub Releases and the in-app updater tracks them automatically. If the download link above does not yet resolve, the first public build has not been published — follow the changelog for the announcement.
What happens when you install
01
Run the installer
The installer registers ZeroWriteService, the elevated component that watches for arriving code. Windows will ask for administrator consent.
02
Choose your telemetry
First run asks separately about crash reports, operational metrics and threat-data sharing. Threat-data sharing is off unless you turn it on.
03
Protection starts immediately
A 14-day full trial begins with no key and no card. Every executable that arrives from that moment is analysed before Windows is allowed to run it.

Verifying your download
Every release is published with a SHA-256 checksum on its GitHub Release page. We recommend checking it — a security tool is exactly the kind of download an attacker would want to substitute.
# PowerShell Get-FileHash .\ZeroWrite-Setup.exe -Algorithm SHA256
Compare the result with the checksum on the release page. If they differ, do not run the installer — report it to us.
