Ladda ner SysManager 1.63.1

[1.63.1] - 2026-08-12
A rare crash that could happen if you closed the window at the exact moment the Bandwidth Monitor was
taking a reading.
Fixed
- Closing the window while the Bandwidth Monitor was mid-measurement could crash the app. In 1.61.9 the network measurement moved onto a background thread so the window stops stuttering. That introduced a small window: if you closed SysManager (or it minimised to tray during shutdown) in the fraction of a second while a measurement was in flight, the finished measurement tried to update a tab that had already been torn down — including its chart, whose drawing resources were already released — which could throw. The measurement now checks whether the tab is still alive before touching anything, and quietly stops if it is not. Only the Bandwidth Monitor tab was affected, and only at the moment of closing.

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-v1.63.1.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-v1.63.1.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
