**[Notes]:** - I have observed that in the [experiment’s targeting expression](https://experimenter.services.mozilla.com/nimbus/device-migration-existing-users-eco2212-en) we have the `os.windowsVersion >= 7` parameter, however, it seems that the browser targets the NT version which is `6.1` for Windows 7. - I have evaluated the `os.windowsVersion` parameter in the "ASRouter" page using `6.1` instead of `7` and the result was `true`. **[Affected versions]:** - Firefox Beta 108.0 - Build ID: 20221208122842 **[Affected Platforms]:** - Windows 7 x64 **[Prerequisites]:** - Have a Firefox en-* locale installed. - Have a Firefox profile older than 28 days. - Have the "[user.js](https://drive.google.com/file/d/1rwitzXBXx4x32Q5_kp8Jmzk7J2dym6-p/view?usp=share_link)" file saved to disk. **[Steps to reproduce]:** 1. Navigate to the profile folder from prerequisites and paste the "user.js" file. 2. Open the browser using the profile from the prerequisites. 3. Navigate to the "about:studies" page and observe the listed experiments. **[Expected result]:** - The "Device migration - Existing users ECO2212 EN" experiment is displayed. **[Actual result]:** - The "Device migration - Existing users ECO2212 EN" experiment is **NOT** displayed. **[Additional Notes]:** - Also a message from the "RSloader" saying that the "device-migration-existing-users-eco2212-en did not match due to targeting" is displayed in the "Browser Console". - This issue is not reproducible on Windows 10 and Windows 11. - This issue is reproducible on all Firefox Versions targeted by the experiment. - Attached is a screen recording of the issue:
