Problem

Ever want to focus without being distracted by email, chat etc? While Slack offers extensive notification settings, there is no way (other than muting all channels) to disable the notification dot Slack's tray icon.

Solution

As it turns out, there is a way to forcefully disable tray notifications by just replacing the respective icon files, which is documented for Linux in this SuperUser question .

To make this fix easily available for Windows users, too, I created a short PowerShell script that backups the default icons (with the notification dot) and replaces them with the dotless icon: github.com/Merlin2001/PowerShell#user-conte..

How To

To use the script, you will first have to edit line 5 and set $currentSlackVersionDir to your actual Slack install directory.

Then you should be able to simply execute the script either directly from within PowerShell or by right clicking and selecting Run in PowerShell.

The catch

The script will only work if you use the "regular" Slack desktop app, not the Microsoft Store version. (This is due to file access restrictions on UWP apps, namely their files only being accessible by SYSTEM.)
