How to Remove CRC-SHA from Windows Context Menu

Learn how to declutter your Windows right-click menu by removing the CRC-SHA option added by 7-Zip, improving your file management experience.

How to Remove CRC-SHA from Windows Context Menu

If you’ve installed 7-Zip on your Windows computer, you may have noticed a new entry in your right-click context menu: CRC-SHA. While this feature can be useful for checking file integrity, some users find it clutters their menu. This guide will show you how to remove the CRC-SHA entry, streamlining your context menu for a cleaner look.

Before we dive into the removal process, let’s briefly explain what CRC-SHA means:

  • CRC (Cyclic Redundancy Check): A method used in digital networks to detect accidental changes to raw data.
  • SHA (Secure Hash Algorithm): A cryptographic hash function designed to verify the integrity of data, often used for downloaded files.

While these functions serve important purposes in data integrity and security, not everyone needs quick access to them through the context menu. If you’re looking to simplify your right-click options, follow these steps to remove the CRC-SHA entry.

Step 1: Open the 7-Zip File Manager. You can do this by typing “7-Zip” into the Windows search bar and pressing Enter.

Step 2: Once the 7-Zip File Manager is open, click on the “Tools” menu at the top of the window, then select “Options” from the dropdown menu.

Step 3: In the Options window that appears, click on the “7-Zip” tab. This tab is usually located next to the “System” tab.

Step 4: Look for the “Context menu items” section within the 7-Zip tab. You’ll see a list of checkboxes for various menu items.

Step 5: Find the checkbox labeled “CRC SHA >” and uncheck it. This action will remove the CRC-SHA option from your context menu.

Step 6: Click the “Apply” button at the bottom of the Options window to save your changes.

Step 7: Click “OK” to close the Options window.

After completing these steps, the CRC-SHA entry should no longer appear in your right-click context menu when you’re working with files and folders.

If you encounter an error message stating “An event was unable to invoke any of the subscribers” after clicking Apply, don’t worry. Simply click “OK” on this error dialog, and the changes should still take effect.

It’s worth noting that removing the CRC-SHA option from your context menu doesn’t uninstall or disable the feature within 7-Zip. You can still access these functions through the 7-Zip File Manager if needed.


By following these simple steps, you’ve successfully decluttered your Windows context menu. Remember, you can always re-enable the CRC-SHA option by revisiting the 7-Zip Options if you find you need quick access to these functions in the future.
