Windows 11 Home supports multiple display languages unless the edition is Windows 11 Home Single Language. First verify the exact edition:
- Go to Start > Settings > System > About.
- Check Edition under Windows specifications.
- If it says Windows 11 Home Single Language, additional display languages cannot be fully installed. In that case, the supported path is to upgrade to Windows 11 Home or Windows 11 Pro.
If it says Windows 11 Home, then English can be used and the current mixed Spanish/English UI is usually resolved by reinstalling and reapplying the display language:
- Go to Start > Settings > Time & language > Language & region.
- Under Preferred languages, confirm English is installed.
- Select English and make sure Language pack is installed.
- Set English as the Windows display language.
- Sign out when prompted, then sign back in.
- If Spanish is still showing in areas such as File Explorer, remove the existing English language and add it again:
- In Language & region, remove English.
- Restart the PC.
- Select Add a language, add English again, and during installation select Set as my Windows display language.
- Sign out and sign back in.
Important: changing the Windows display language can also change the keyboard layout at sign-in. Check the input language icon on the sign-in screen before entering the password.
If the interface still remains partially in Spanish after reinstalling the language pack and signing out/in, an accepted Microsoft Q&A resolution for this exact mixed-language behavior is an in-place repair install using the English Windows 11 ISO while keeping files and apps. Back up files first before proceeding.
Also note that Windows 11 does not support cross-language upgrades. During upgrades or migrations, the upgrade is supported only to the system default UI language, which can contribute to mixed-language results after an upgrade.
