SysManager 1.64.3 aflaai

[1.64.3] - 2026-08-12
The Standby List Cleaner used to keep checking your memory every two seconds for as long as SysManager
stayed open, even after you left the tab. It now stops when you are not looking at it.
Fixed
- The Standby List Cleaner kept working in the background after you left it. Opening that tab once started a check every two seconds — and it never stopped: not when you switched to another tab, not when you minimised the window, and not when you closed SysManager to the notification area. On a laptop that is wasted battery for a tab nobody is looking at, and if you had turned on automatic purging, that could run unattended from a hidden tab. The check now runs while the tab is open, and stops when it is not. Automatic purging still works exactly as before — if you have turned it on, SysManager keeps watching your free memory in the background, because that is the whole point of the setting; the check only stops when there is nothing it could act on. Every other tab that watches something live already worked this way; this one had been left out, and a new automatic check now makes sure a future tab cannot be missed the same way.

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-v1.64.3.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-v1.64.3.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
