Sækja SysManager 1.64.7

[1.64.7] - 2026-08-12
Internal hardening in the "go back to the previous version" check. Nothing you do with SysManager changes.
Fixed
- The rollback check could keep a saved version locked if reading it failed unexpectedly. Before starting your previous version, SysManager opens the saved copy, locks it so nothing can swap it, and checks it against a recorded checksum. Every ordinary outcome — checksum missing, unreadable, or not matching — released that lock correctly. But if reading the file failed in an unusual way, the lock could be left in place until SysManager closed, and while it was held, no future update could refresh your saved copy — so you could quietly end up with an out-of-date version to go back to. The lock is now released the same way on every possible outcome, including ones that have not happened. Found by the project's own automated security scan flagging code added in 1.64.2; nobody reported it, and no user is known to have hit it.
Verify the download
Get-FileHash .\SysManager-v1.64.7.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-v1.64.7.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-v1.64.7.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
