Verify the file you downloaded

Run this against the file on disk. If the output does not match the hash below, the file is not what Simon Tatham published. Delete it.

Got a different hash, or one you cannot place? Paste it into the hash checker and it will tell you which program and version it belongs to, past releases included.

Install PuTTY silently

This installer is an MSI package, so it takes the standard Windows Installer switches. That is a property of MSI itself rather than something the publisher declared.

64-bit · machine scope · MSI convention

msiexec /i "putty-64bit-0.84-installer.msi" /qn /norestart

32-bit · machine scope · MSI convention

msiexec /i "putty-0.84-installer.msi" /qn /norestart

ARM64 · machine scope · MSI convention

msiexec /i "putty-arm64-0.84-installer.msi" /qn /norestart

Run 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.

Uninstall PuTTY cleanly

Every guide on this tells you to hunt for the product code with Get-WmiObject or in the registry. You do not need to: it is published in the installer manifest, and it is printed below.

Product code · 64-bit

{FEE89B49-1A47-476C-864C-1D5076FC2891}

Uninstall, with the usual prompts

The product code changes with every version

The codes above belong to PuTTY 0.84.0.0, the version in our index. If you have an older release installed, its code is different and this command will report that the product is not installed. In that case run Get-Package -Name "PuTTY*" in PowerShell to read the code of what you actually have.

This removes the program as the publisher packaged it. Settings and files created after installation, typically under AppData, are deliberately left behind by the uninstaller and have to be deleted by hand if you want them gone.

Reinstalling and hitting error 1638? That is this same product code, and the command above is the fix.

Extensions PuTTY registers itself to handle.

Is PuTTY safe to download?

Yes, in the sense we can actually verify: the installer downloads from earth.li, which is a domain we have tied to Simon Tatham.

Every one of the 6 installers on this page comes with the SHA-256 Simon Tatham declared, so you do not have to take our word for it: hash the file you downloaded and compare.

What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.

If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.

How the 100/100 score is calculated · why the source matters more than the reputation

Install PuTTY with winget

Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.

Install

winget install --id PuTTY.PuTTY --exact

Upgrade later

winget upgrade --id PuTTY.PuTTY

Why --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.

Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.

Old versions of PuTTY10 with hashes

The version history of PuTTY, 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.
