Checking Your AtlasOS Version
Knowing which version of AtlasOS you have installed is important, especially when considering updates or troubleshooting. As mentioned in our Updating AtlasOS guide, different versions have different update paths and support levels.
There are two primary ways to check your installed Windows version, which corresponds to your AtlasOS version:
1. Using the winver
Command
This is a quick way to see your Windows build number and the Atlas Playbook version.
- Press Win+R on your keyboard to open the Run dialog.
- Type
winver
and press Enter or click OK. - A window will appear showing your Windows version and OS Build number. Below the user name, you should also see the Atlas Playbook version installed (e.g.,
Atlas Playbook v0.4.1
).

2. Using Windows Settings
You can also find detailed system information, including the Atlas Playbook version, in the Settings app.
- Open Windows Settings (you can press Win+I).
- Navigate to
System
. - Click on
About
. - Look directly under your PC's name (e.g.,
DESKTOP-PDSCPN3
). You should see the Atlas Playbook version listed there (e.g.,Atlas Playbook v0.4.1
). - Further down, under the "Windows specifications" section, you'll find the base Windows Edition (e.g., Windows 11 Pro) and the Version number (e.g., 22H2).

By checking the Atlas Playbook version using either of these methods, you can easily identify your installed release, helping you follow the correct update procedures or seek appropriate support.
