Install and Use Slack on Windows

Slack is a popular chat app for teams. You work in channels, share files and have quick conversations. This guide shows how to install Slack on Windows, create a workspace and invite colleagues.

What is Slack?

Slack is a messaging platform built around workspaces and channels. Each channel is about a team, project or topic. You can send messages, share files and start quick audio or video calls (huddles).

Microsoft Teams offers much the same, plus full meetings, calling and tight integration with SharePoint, OneDrive and Outlook. If your organization uses Microsoft 365, you probably already have Teams. You'll often run into Slack with customers, partners or communities.

Create an account

Go to slack.com and click Sign in or Get started.

Rather not install anything? Slack also works in the browser at app.slack.com.

Install Slack on Windows 10 or 11

Go to slack.com/downloads/windows and click Download.
Open the downloaded file. Slack installs and starts automatically.
Click Sign in to Slack. Your browser opens, you pick your workspace and return to the app.

Create a workspace

New to Slack and no invitation yet? Then create a workspace yourself.

Click Create a workspace.
Give your workspace a name, for example your team or company name.
Choose whether anyone with the same email domain can join on their own, so you don't have to invite everyone separately.

Invite colleagues

Invite people by email address or with an invite link. Click your workspace name and choose Invite people. Copy invite link gives you a link you can share.
