SysManager 1.136.40 download

[1.136.40] - 2026-10-31
Performance Mode no longer adds another copy of the Ultimate Performance plan at every Apply, on
Windows in a language other than English.
Fixed
- Windows Home and Pro hide the Ultimate Performance plan, so SysManager switches to a copy of it,
and Windows names that copy in its display language. Outside English the copy was never found
again, so every Apply of Ultimate Performance, and every game mode start with its Ultimate
Performance step on, added another identical plan to Power Options, and the tab did not tick
Ultimate Performance while the copy was the active plan. SysManager now remembers the copy it
made and uses it again for as long as Windows lists it. Copies made by earlier versions stay in
Power Options, where they can be deleted. This was there since Performance Mode was added in
0.12.0.

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. Two checks
run on their own when SysManager starts: the version check against the GitHub Releases
API, at most once a day, and the Dashboard's app-updates alert, which asks winget. The
About tab can switch off either. Everything else that uses the network runs only when you
use 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-v1.136.40.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-v1.136.40.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
