Create and Test with a New Windows User Profile

Since the issue often stems from corrupted user profile font caches or display configurations, testing with a fresh profile can isolate and resolve the problem.

Corrupted font caches or misconfigured display settings in a specific Windows user profile can prevent Word and Excel from rendering Cyrillic text correctly. Testing on a new profile helps confirm if the system itself is fine but the user data is corrupted.

1
Open Windows Settings

Click the Start button and select the Settings gear icon, then navigate to 'Accounts'.

2
Add a New User

Select 'Family & other users' from the left sidebar, click 'Add someone else to this PC', and follow the prompts to create a new local account.

3
Log into the New Profile

Sign out of your current Windows profile and log in using the newly created account credentials.

4
Test Document Display

Open Microsoft Word or Excel in the new profile and check if the Cyrillic characters and punctuation render properly.

Create and Test with a New Windows User Profile
Profile Migration: If the document displays correctly in the new profile, your original profile is corrupted. You can either migrate your files to the new profile or consider resetting Windows to fix the underlying system corruption.

Frequently Asked Questions

Why do Cyrillic characters show as squares in Word and Excel?

This typically happens when the required fonts are missing, the Windows font cache is corrupted, or there is an issue with the specific Windows user profile's display configuration causing the system to substitute unknown characters with empty boxes.

Does changing the display language in Office fix the square boxes?

If the underlying issue is a corrupted user profile, simply changing the display language will not help. However, ensuring the correct Windows language pack is installed can resolve issues if they are caused by missing system fonts.

Will reinstalling Office fix the font rendering problem?

Running an Online Repair often resolves file-level corruption within Office. If the issue persists after a repair, it is highly likely related to the Windows operating system or the user profile rather than the Office application itself.
