Latest Stable PuTTY Release
How Putty.info verifies the stable release
Independent resource: Putty.info is not the official PuTTY website. We read the publisher’s public latest page, store a snapshot, and surface verified package links. We do not redistribute the binaries.
Our release monitor fetches the official latest release page, parses the stated version and release date, and collects MSI/EXE/ZIP links only when they point at allowlisted hosts (including the official the.earth.li package host). Low-confidence parses never replace the last good verified record.
The sidebar on this page (and the homepage release card) show the last successful verification timestamp in UTC. Treat that timestamp as “when we last confirmed the publisher page,” not as a marketing freshness badge.
Recommended package for most Windows PCs
For mainstream Intel/AMD Windows machines, open the official 64-bit x86 MSI installer. On the publisher page that row is labeled “64-bit x86” and the filename follows putty-64bit-<version>-installer.msi. Each installer row also has a GPG signature link — use it when your environment requires cryptographic verification.
Deep links from Putty.info always disclose the destination hostname and go through /go/official-download/ so analytics can record that you left for an allowlisted host without Putty.info ever serving the file bytes.
Other architectures on the same official page
- 64-bit Arm MSI — Windows on Arm (
putty-arm64-*-installer.msi) - 32-bit x86 MSI — legacy machines only
- 32-bit Arm MSI — niche Windows on Arm / IoT cases
- Standalone EXE + zip — portable or scripted installs, still architecture-specific
- Unix source .tar.gz — for building from source on non-Windows platforms
Architecture mistakes are common when people search “putty.exe download” in a search engine and land on a page that does not show the official row labels. Prefer the publisher’s labeled MSI table or our verified release card.
Official documentation for this release line
Behavioral details — sessions, host keys, Pageant, PuTTYgen, PSCP/PSFTP, Plink, tunnels, and the project’s own error-message explanations — live in the PuTTY User Manual published with the release. Putty.info’s guides are educational companions; when a UI label or protocol detail matters for compliance work, confirm it against that manual and the project changelog.
Stable release vs development snapshot
Stable releases are what Putty.info marks as verified for general use. Development snapshots may include newer fixes and newer bugs. Do not treat a snapshot as the “latest stable” just because the build date is newer. See stable vs snapshot and development snapshots.
Next steps after downloading
- Verify the file you received.
- Follow how to use PuTTY for a first SSH login.
- Read host key warnings before clicking through unfamiliar fingerprints.
- Use the troubleshooter if the session fails before a shell appears.
Checksums, keys, and release hygiene
Every official package row on the latest page includes a signature link. The page also publishes aggregate checksum files (MD5, SHA-1, SHA-256, SHA-512) with their own signatures. Operational teams that mirror PuTTY internally should pin a version, verify signatures with the project keys page, and re-verify when promoting a new release—not when a random mirror updates a filename.
Putty.info will never invent CVE advisories from incomplete HTML scrapes. Security pages on this site explain practices (host keys, Pageant risks, fake downloads) and point at the project wishlist/security materials when automated advisory rows are not confidently available. See security center, signatures, and source policy.
