Install RegCool silently
The unattended switch below is the one Kurt Zimmermann declares in the installer manifest, not one we guessed by trying flags.
32-bit · publisher-declared
.\RegCool.exe /si /st /deRun it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.
How we scored this 96 out of 100
| Signal | Finding | Points |
|---|---|---|
| SHA-256 hash published | 1 of 1 installers ship a SHA-256 hashWithout a published hash there is no way to prove the file you downloaded is the file the publisher built. | 30 / 30 |
| Binary provenance | 1 on the publisher's own domainThe strongest signal against a repackaged installer: the file should come from the publisher, not from a mirror nobody vouches for. | 35 / 35 |
| Served over HTTPS | 1 of 1 over HTTPSAn installer fetched over plain HTTP can be modified in transit. | 15 / 15 |
| Release recency | last release about 6 months agoSoftware that has not shipped in years accumulates unpatched vulnerabilities. | 11 / 15 |
| Licence declared | FreewareA declared licence tells you what you are actually allowed to do with the software. | 5 / 5 |
Old versions of RegCool2 with hashes
The version history of RegCool, each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

Publishers take old builds offline without warning, so a link here can stop working even though the hash stays correct forever. If you already have the file, the hash is what matters: it tells you whether what you have is what they published.
