Sækja SysManager 1.64.6

[1.64.6] - 2026-08-12
Closing a tab, or closing SysManager, now actually stops what that tab was doing. Scans, cleanups and
file shredding used to keep running in the background after you closed them.
Fixed
- Work carried on after you closed the tab or the app. Every tab that runs something you can wait on — a scan, a cleanup, a speed test, shredding files, the one-click Tune-Up — is supposed to stop when you close it. Behind the scenes, SysManager was releasing the "stop" signal without ever giving it, so 28 of those operations across 23 tabs simply carried on: file shredding kept overwriting files after you closed the window, Deep Cleanup and the browser cleaner kept deleting, a speed test kept using your connection, and the Tune-Up kept changing settings. Nothing was corrupted by this — the work was real work you had started — but it continued when you had every reason to think it had stopped, and it kept your PC busy after SysManager appeared to be gone. All of them now stop when you close the tab or quit, exactly as the Cancel button already did. A new automatic check makes sure a future tab cannot be added with the same mistake.
Verify the download
Get-FileHash .\SysManager-v1.64.6.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-v1.64.6.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-v1.64.6.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
