     - If you previously have a MagiskOnWSA installation, it will automatically uninstall the previous one while **preserving all user data** and install the new one, so don't worry about your data.
     - If you have an official WSA installation, you should uninstall it first. (In case you want to preserve your data, you can backup `%LOCALAPPDATA%\Packages\MicrosoftCorporationII.WindowsSubsystemForAndroid_8wekyb3d8bbwe\LocalCache\userdata.vhdx` before uninstallation and restore it after installation.) (If you want to restore the icons to the start menu, please install and use [WSAHelper](https://github.com/LSPosed/WSAHelper/releases/latest).)
     - If the popup windows disappear **without asking administrative permission** and WSA is not installed successfully, you should manually run `Install.ps1` as administrator:
