How to Fix Microsoft Word Spell Checker Not Working?

Is your Microsoft Word spell checker not working suddenly and isn’t detecting any spelling and writing mistakes?

Microsoft Word is a special word-processing software released by the namesake company that many people are familiar with and continue to use today. Almost everyone is familiar with Microsoft Word and how it helps us complete everything from school assignments to comprehensive reports that help us get through our jobs.

The software is equipped with several tools that you can use to simplify your documents while making them easier to read and understand. A spell checker is a nifty tool that many users find helpful as it helps you fix any spelling and grammatical mistakes.

Despite this usefulness, the tool has limitations and is prone to suddenly stop working altogether while you are still writing or editing your documents. Microsoft Word might be unable to detect any spelling and grammar mistakes if you encounter this issue which can take a toll on your productivity.

 

Types of Microsoft Word Spell Checker Errors

Several users who frequently use Microsoft Word have reported problems with the spell-checker function. This problem usually manifests in the software’s inability to detect any wrongly spelled words through its red underlines and offer suggestions to correct them. Another example of this problem is Word failing to automatically correct any wrongly spelled words and incorrect syntax and capitalization in the document.

Both instances of the spell checker misbehaving all boil down to a malfunction with the feature itself. This can be caused by something going wrong with the software or the system you are typing it on.

With everything in mind, we prepared this guide that will cover 5 common reasons why your spell checker might not be working as well as 8 fixes that you can try out that will try to fix and improve the situation.

All the fixes you find here will cover simple and basic troubleshooting fixes to more complicated and complex fixes you need to make with your system. With that out, let’s get down to fixing your spell checker!

 

 

Why is the Spell Check Feature in Microsoft Word Not Working?

1. The Spell Checkers Weren’t Installed into Your Microsoft Word

You might not be able to use the spell checker feature because the feature wasn’t installed in your Microsoft Word. While the Office installer ensures that your installations will be clean, it might not always be able to catch and fix all errors which can lead to this happening.

This happens during the installation process as Microsoft Word (and Office in general) supports “Add-ins” from their official site and third-party applications that can make your encoding process significantly easier. The spell checker function is considered an “Add-in” and might’ve not been added to your Microsoft Word during installation.

If you can’t access your spell check using the Review tab or shortcut button (F7, for example), the feature might not be installed. You can quickly resolve this problem by installing the proofing tools (Step 1) or repairing your Microsoft Office software lineup altogether (Step 2).

 

 

2. The Language You Are Typing in is Disabled in Add-ins

Recent versions of Microsoft Word tend to have more lenient and comprehensive spell checkers in contrast to the older versions, like 2003 and lower. Typing in different languages in newer versions is made more accessible by changing your speller language to that specified language.

Following the language you are typing in is essential for the spell checker. The feature tends to stop working entirely if you have too many spelling/grammar errors resulting from typing in another language.

In either scenario, you want to enable the language you are typing in (Step 3) so that you cannot only catch any spelling and grammar mistakes but also have your spell checker working and ready to go when you are ready to do any more encoding.

 

 

3. Spell Checker Feature was Disabled

Similar to the first reason, the spell checker feature might not work because you have the function disabled. It is possible for the spell checker feature to be installed but disabled either by you or your system automatically.

Microsoft Word’s spell checker functions in 2 ways. You can manually activate it and check for any errors after you have finished typing your document, or you can have it work alongside you to make any edits on the fly as you encode.

Regardless of how you prefer your spell checker to function, in either situation, you’d want to double-check your spell checker feature and re-enable it (Step 4), mainly if you are used to the latter version of the way spell checker functions.

 

 

4. Another Language was Set as your Default Option

Continuing from the second reason, your spell checker might not be working because you might’ve selected another language as your default one for the document you are working on. This situation would rarely pose a problem with your spell checker but can become very problematic and confusing when it does happen.

If this happens, you want to re-select the language option that your spell checker will use (Step 5) to ensure that it is following the right one to base its spelling and grammar.

 

 

5. Your Computer blocked the Feature

The last reason your feature might not be functioning at all might be a combination of several things that can lead it to get blocked 🛑 and falsely flagged🏳️ as malicious by your computer.

Microsoft Word can run and function almost as well, even if your spell checker is blocked, provided that no key features are also blocked. Since the spell checker feature is considered an add-on, the software can continue running, albeit without the feature working.

There are several workarounds and fixes that you can take to address this problem, with the first workaround being opening your document (and by extension Microsoft Word) in Safe mode (Step 6), with the following fix being to unblock and whitelist Microsoft Word from your Security (Step 7). Finally, you can modify your computer registers related to the spell checker feature and Microsoft Word (Step 8).

 

 

8 Fixes for When Microsoft Word Spell Checker is Not Working

1. Installing Proofing Tools for Microsoft Word

Typically, Microsoft Office installs all the essential features you might need with Microsoft Word when you first install it. In some cases, however, the features might not be installed due to a bug or glitch.

Luckily, you can still fix this problem by manually installing the feature by following these steps:

  1. Open your Control Panel by searching it on your Computer.

2. Repair Microsoft Office

Please wait for the repair request to be finished and for the prompt that it was successful. Once the repair is finished, restart your computer and launch Microsoft Word to see if the problem is fixed.

 

Note: As the name suggests, Online Repair will require a stable internet connection to proceed as it will attempt to redownload any broken files. We only recommend choosing this if you have access to stable internet and as a last resort.

 

 

3. Re-Enable the Language you are Typing in (e.g., EN-US)

There are some instances of the spell checker language getting randomly disabled due to a bug or glitch with Microsoft Word. This rarely gets fixed automatically unless you reinstall the program, which is why you would want to check if it was disabled entirely. 

Here’s what you can do to be able to do just that:

  1. Launch Microsoft Word and Select “File” from the menu.

Re-enable the language you are typing in

 

After following the steps above, we recommend you restart your Microsoft Word to ensure that any changes you make will be applied.

 

 

4. Enable the Spell Checker Feature in Microsoft Word

Similar to the previous fix, you also want to check the spell-checking and proofing function entirely in your Microsoft Word to see if it was enabled correctly and running. If it was disabled in the last step, there’s a high chance that you need to re-enable it.

Here’s how you can do it:

  1. Launch Microsoft Word and Select “File” from the menu.

7. Whitelist Microsoft Office From Your Security

Microsoft Word (and Office) can run even if it gets blocked by your system. However, if they are running, certain features will become unavailable, such as the spell-checker. Whitelisting Office will fix any issues related to this, and it can be done through these steps:

  1. Open “Windows Security” or something similar to that feature/function in your System.

Your registry is what holds all the software and its respective features that are installed on your computer. Your spell checker might not be working in Microsoft Word due to an incorrect value in your registry that you would need to fix manually.
