# Uninstall on Windows

This guide will help you perform a complete uninstall of WebSpellChecker Server on a Windows-based environment.

If you have any custom settings and/or dictionaries that you plan to reuse, you need to back up them before uninstalling, migrating, and upgrading.

For example:

* If you have already changed any values of the [AppServer parameters](/v6.12.0/deployment/configuration/application-server/appserver-parameters.md) in the AppServerX.xml configuration file, you may need to transfer these settings to a new server. Otherwise, these parameters' values can become incompatible.
* Back up the **CustomDictionaries** folder (\<WebSpellChecker\_Installation\_Path>/AppServer/CustomDictionaries) with global custom dictionaries and its CustDictConfig.xml configuration file.
* Back up the **UserDictionaries** folder (\<WebSpellChecker\_Installation\_Path>/AppServer/UserDictionaries) with all personal user dictionaries created by end users.
* Back up the **StyleGuide** folder (\<WebSpellChecker\_Installation\_Path>/AppServer/StyleGuide/client) with global style guide rules.
