SysManager 1.64.4 download

[1.64.4] - 2026-08-12
Choosing "close SysManager" now actually closes it. It used to leave SysManager running invisibly, with
no window and no icon next to the clock to get it back.
Fixed
- "Close SysManager" left it running with no way to see it or stop it. When you press X, SysManager asks once whether to keep running next to the clock or close completely — and remembers your answer. Choosing to close completely made the window disappear, but the program kept running: no window, and no icon next to the clock either, so there was nothing to click. Worse, it then blocked itself from starting again — launching SysManager would hand over to the invisible copy and quit immediately, so it looked like the app simply would not open. Because your answer is remembered, this happened every time, and the only way out was Task Manager. Closing completely now really does end the program. Keeping it next to the clock, and pressing Cancel to go back, both work exactly as before.
Verify the download
Get-FileHash .\SysManager-v1.64.4.exe -Algorithm SHA256

This build is not code-signed, so Windows will warn on first launch. That is
expected for a small independent app: see what the warning says and what to
click.
Code signing is planned through the SignPath Foundation,
which provides free certificates to open-source projects, with signing performed by
SignPath.io. Until then, the SHA256 above and the build
attestation below are what establish that a download is the genuine build.

Verify where this binary came from
This exe was built by GitHub Actions from this public source, and the build is
recorded in the Sigstore public transparency log. With the
GitHub CLI:
gh attestation verify .\SysManager-v1.64.4.exe --repo laurentiu021/SystemManager
That proves which commit and workflow produced this exact binary, something the
SHA256 file cannot show, since it is published alongside the exe it describes.
Each release also ships SysManager-v1.64.4.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
