Kayzen Updater Free · Windows · Free
Your software up to date, without losing an evening.
Kayzen Updater Free finds the everyday software installed on your PC (browsers, PDF readers, utilities), compares it with the latest published versions and updates it in one click. Free, no account and no ads.
StatusComing soon
Kayzen Updater Free cannot be downloaded yet: it will be published once it is signed with our publisher certificate.
How it works
PC scan
The app finds installed software covered by the Kayzen catalogue, a signed list of common third-party applications.
Version check
For each one, it compares the installed version with the latest published version and shows you what is out of date.
One-click update
You choose what to update. The installer is downloaded from the publisher, verified, then installed.
Nothing is installed without verification
An update tool installs programs on your PC. These are the rules it applies every single time.
Signed catalogue
The catalogue is signed (Ed25519) and carries an expiry date. A catalogue that has been altered, has expired or is older than the one already received is rejected.
Downloaded from the publisher
Each installer is downloaded only from the software publisher's own website.
Double verification
Before any installation, the file's SHA-256 hash and the publisher's Authenticode signature are checked. If either check fails, nothing is installed.
Confirmed entries only
Only software whose catalogue entry has been confirmed can be installed. Everything else is only reported.
Administrator rights at the right time
Windows administrator approval (UAC) is requested only when an update is about to be installed.
Never a downgrade
Software is never rolled back to an older version. Updates to the app itself are signed (Ed25519) and verified before installation.

FAQ
Frequently asked questions
Why can't I download it yet?
We are waiting for our publisher code-signing certificate (Authenticode). Publishing without it would trigger Windows SmartScreen warnings and would not let you verify that the file really comes from Kayzen. We would rather wait.
Is it really free?
Yes: no account, no ads and no usage data collection.
Which software is supported?
The software in the Kayzen catalogue: common third-party applications such as browsers, PDF readers and utilities. Software whose entry is not confirmed is only reported, never installed.
What happens if a check fails?
The installation is cancelled: an installer whose hash or signature does not match is never run.
Do I need to be an administrator of the PC?
Not to install the app, which installs for your account only. Windows asks for administrator approval only when a software update is about to be installed.
Does it work on Mac or Linux?
No. Kayzen Updater Free is a Windows application (Windows 10 version 1809 or later, 64-bit).
