SysManager 1.66.5 ڈاؤن لوڈ

[1.66.5] - 2026-08-24
Performance Mode will no longer mistake a running game profile's settings for your own. Start a profile,
then change something in Performance Mode for the first time, and it used to write down the profile's
power plan as "how you had it" — so a later Restore All would put you back onto a gaming plan you had
never chosen.
Fixed
- Performance Mode asks you to stop a game profile before it records your original settings. While a
profile is running, the power plan and visual effects on the machine are the profile's, not yours. The
tab now says so and refuses to save them as your baseline, instead of silently keeping borrowed values
it would restore you to later. Nothing is changed when it refuses.
- A baseline saved before a profile started is still loaded and used normally, so the protection does
not stop the tab working during a game — it only declines to invent a new baseline out of the profile's
own settings.
Verify the download
Get-FileHash .\SysManager-v1.66.5.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.
Code signing policy
This release is not code-signed. The team roles, release-approval process and
privacy policy required by the SignPath Foundation programme
are documented in advance under Code signing
policy. That
documentation is a prerequisite for applying, not evidence of a certificate. The
attribution line naming SignPath as the signing provider will appear here once a
certificate is actually issued.
This program will not transfer any information to other networked systems unless
specifically requested by the user or the person installing or operating it. Full
privacy policy.
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-v1.66.5.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-v1.66.5.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
