Installing the Language Pack
The foundation of any spellcheck capability is the presence of the correct Language Pack. Windows does not automatically download dictionaries for every possible language; they must be explicitly installed through the system settings. Begin by opening the Settings application using the Win + I keyboard shortcut. Navigate to the Time & language section, which serves as the central hub for all regional and linguistic configurations.
Within this menu, select Language (or Region & language in newer builds). Click the Add a language button located at the top of the list. A comprehensive dialog will appear, allowing you to search for your desired language by name or code. Select the appropriate entry from the results. It is crucial to note that some languages may have multiple variants, such as English (United States) versus English (United Kingdom), each with distinct spelling rules. Choose the variant that matches your intended writing style.
Once selected, proceed by clicking Next. The installer will present a screen titled Install options. Here, you must ensure that the checkbox for Offline spelling, typing, and OCR is checked. This option is non-negotiable for spellcheck functionality, as it downloads the necessary dictionary files to your local machine. If you rely on cloud-based corrections, you may also check online services, but offline support guarantees availability even without an internet connection. Finally, click Install and wait for the process to complete. This may take several minutes depending on your network speed and the size of the language pack.
Configuring Spellcheck Options
After installation, the language appears in your list, but spellcheck might not be active by default. You need to verify the specific features enabled for that language. Return to the Language page in Settings and locate your newly added language in the list. Click on the language name to expand its detailed options.
Look for the Spelling section. Ensure that the toggle for Spell check is turned on. In some versions of Windows, this setting might be nested under a submenu labeled Options or directly visible as a switch. If you do not see a direct toggle, look for a link labeled Typing or Editor which leads to more granular controls. Here, you can confirm that Show red squiggly lines is enabled. This visual indicator is what alerts you to potential typos in real-time.
If you are using Microsoft Office applications, note that they often maintain their own independent spellcheck settings. However, the underlying dictionary provided by the Windows Language Pack is the source data. If spellcheck fails in Word after configuring Windows, you may need to open Word, go to File > Options > Proofing, and ensure the correct proofing language is selected in the dropdown menu. This step aligns the application with the OS-level configuration.
Troubleshooting Missing Spellcheck
Users frequently encounter situations where the language is installed, yet no red underlines appear when typing errors. This issue usually stems from the language not being set as the primary editing language or from corrupted dictionary files. First, verify that the language is set as your primary display language or at least listed above other languages in the preferred order. Sometimes, Windows defaults to the first language in the list for spellchecking purposes.
To reset the language pack if it appears broken, you can remove and reinstall it. Go back to Settings > Time & language > Language. Click on the problematic language and select Remove. Confirm the deletion. Then, repeat the installation process described earlier. This fresh install often repairs missing dictionary components that cause silent failures. Additionally, ensure that your Windows operating system is up to date, as language packs are frequently patched via Windows Update to fix bugs in grammar checking algorithms.
Another common oversight involves the context of the text. Spellcheck typically only activates in editable fields. If you are viewing a PDF or a static image, no spellcheck will occur regardless of your settings. Furthermore, some browsers require extensions for spellchecking web forms if the built-in engine is disabled. For native Windows apps and Office suites, however, the system-level configuration is sufficient.
If you manage multiple languages, you might want to streamline your experience.

This prevents accidental switching between input methods while typing.
Frequently Asked Questions
Why is spellcheck not working in Microsoft Word?
Microsoft Word often overrides system settings with its own internal language preferences. Open Word, go to Review > Language, and ensure the correct proofing language is selected. Also, check File > Options > Proofing to make sure "Check spelling as you type" is enabled.
Can I use spellcheck without installing the full language pack?
No, the spellcheck feature relies entirely on the offline dictionary files contained within the Language Pack. Without installing the pack and enabling the offline spelling option, Windows has no data to compare your typed words against.
How do I remove a language pack I no longer need?
Navigate to Settings > Time & language > Language, click on the language you wish to remove, and select the Remove button. This frees up disk space and removes the associated spellcheck capabilities for that locale.
Does changing the display language affect spellcheck?
Changing the display language alters the interface menus but does not necessarily change the proofing language. You can have a French display language while keeping English spellcheck active, provided both packs are installed and configured correctly in the Typing settings.
What should I do if red squiggly lines disappear?
Verify that the Spelling toggle is active in the language options. If it remains off, try removing and reinstalling the language pack to repair corrupted dictionary files. Ensure you are typing in a supported application that utilizes the system editor.
