If you find a security problem in WinScreen, please tell us privately first:

• Use Report a vulnerability on the Security tab, or
• Open an issue that only says you found a security problem, and we'll find a private way to talk. Please leave the details out of the issue.

We'll reply as soon as we can and let you know when it's fixed.

Fixes go into the newest release, which is for Windows 10 and 11 on 64-bit Intel or AMD PCs (x64). The earlier ARM64 builds are no longer updated.

WinScreen only installs an update after checking it against a signature built into the app, so an update can't be swapped for something else on the way. Automatic updates are off until you turn them on.

The installer isn't code-signed yet, so Windows may warn you the first time you run it. Download it only from this project's Releases page.
