How to Remove Unused Language Pack Files on Windows

Before You Clean

Language packs and input features are installed capabilities. Do not delete their files as cache or remove languages another user needs.

Review and Clean Manually

1. Review Settings > Time & language > Language & region with the computer’s users.

2. Keep the display language and required keyboard layouts. Select an unused language and use its Remove control if available.

3. Review language options and installed optional features for speech or handwriting. Remove only features you have confirmed are unnecessary.

4. Complete any requested sign-out or restart, then verify the remaining display and input languages. Managed devices may require the administrator’s policy.

Where Kudu Helps

Kudu’s cache cleaner does not decide which languages to uninstall. Use Windows’ language and optional-feature controls for this task.
