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.

  1. Press Win+R on your keyboard to open the Run dialog.
  2. Type winver and press Enter or click OK.
  3. 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.

  1. Open Windows Settings (you can press Win+I).
  2. Navigate to System.
  3. Click on About.
  4. 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).
  5. 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).
