Check for Updates

Under the Product Information section, click on the 'Update Options' drop-down button and select 'Update Now'.

Frequently Asked Questions

Why do my Excel cells suddenly turn black when I press Enter?

Black cells in Excel are usually caused by graphics rendering issues, outdated display drivers, or hardware acceleration conflicts. Updating your Office application via File > Account, or updating your Windows display drivers, can resolve these visual glitches.

Can background applications cause Excel to type data in the wrong cell?

Yes. Background programs such as third-party clipboard managers, screen recorders, or aggressive antivirus software can steal window focus. This interrupts Excel's input tracking, causing your keystrokes to register in unintended neighboring cells. Running a Windows clean boot can identify the culprit.

How do I know if the freezing is caused by my workbook or the Excel app?

To isolate the issue, create a brand-new, blank workbook in Excel. If you can type and press Enter without experiencing freezing or black cells, your original workbook file is likely corrupted or too large. If the issue occurs even in the blank file, the Excel app or Windows profile is the source.
