Simple Chromium Updater (chrupd.cmd)

Self executable PowerShell script to auto update Chromium for Windows

Latest version: 20210122 (

This script uses the feed from to download and install the latest Chromium version, if a newer version is available.

When you run the script it does the following:

  • by default it'll get the "stable" 64-bit Installer by "Hibbiki"
  • verifies SHA1/MD5 hash and runs installer

Options can be set in script or by using command line arguments.

Download and run chrupd.cmd or see below for details.


Make sure the combination of editor and channel is correct. You can also use chrupd.cmd -list. For more information about versions check, it's feed and

Editor Channel
Marmaduke stable, dev
Marmaduke-Ungoogled stable
RobRich dev
The Chromium Authors dev
ThumbApps dev
Hibbiki stable, dev

( defaults in bold )

Scheduled Task

Optionally you can add a Scheduled Task by using chrupd.cmd -crTask. A VBS wrapper will be written to chrupd.vbs which is used to hide it's window. Option noVbs disables the wrapper, this will however cause a flashing window when the task runs.


The script auto updates (since v20210109).

To manually update to a newer version just replace "chrupd.cmd". Copy "editor" and "channel" if set. If you have Scheduled Task setup you do not need to change the task.

File Formats

For easy execution this PowerShell script is embedded in a Batch .CMD file, which can be renamed to .PS1.

See docs/ for details.

Note: this script has no connection to the preexisting ChrUpdWin.cmd Batch file by Michael Kharitonov
