…rs on Windows (#23287) # Why Fixes #23252 # How - `open` has a bug on Windows, where it [uses `process.env.SYSTEMROOT`](https://github.com/sindresorhus/open/blob/main/index.js#L173) instead of [`process.env.SystemRoot`](https://en.wikipedia.org/wiki/Environment_variable#:~:text=The%20%25SystemRoot%25%20variable%20is%20a,including%20the%20drive%20and%20path.) - This causes the executed command to run with `undefined\\...` - There has been no fix yet, and due to `open` being fully ESM now, we probably can't upgrade too > See various issues [#300](sindresorhus/open#300), [#292](sindresorhus/open#292), [#270](sindresorhus/open#270), or [#205](sindresorhus/open#205) This basically sets the missing `SYSTEMROOT` when trying to open a browser on Windows. It's fixed in both `@expo/cli` as well as `@expo/dev-server` (to open the Chrome DevTools). # Test Plan This has to be tested on Windows. - `$ yarn create expo ./test-browser -t tabs@beta` - `$ cd ./test-browser` - `$ yarn start` - Try pressing the following keys: - `j` -> to open the Chrome DevTools, after connecting a device. Should work as expected. - `w` -> to open the browser with Metro web. Should work as expected. # Checklist  - [ ] Documentation is up to date to reflect these changes (eg: https://docs.expo.dev and README.md). - [ ] Conforms with the [Documentation Writing Style Guide](https://github.com/expo/expo/blob/main/guides/Expo%20Documentation%20Writing%20Style%20Guide.md) - [ ] This diff will work correctly for `npx expo prebuild` & EAS Build (eg: updated a module plugin). --------- Co-authored-by: Expo Bot <34669131+expo-bot@users.noreply.github.com>
