If you have installed the latest version of the 7-Zip program on your Windows machine, you might have noticed the entry CRC-SHA has been added automatically to the context menu, alongside 7-Zip options. If you point the side arrow, it displays, CRC-64, SHA-256, SHA-1, CRC-32, and * entries.
CRC is an abbreviated form of Cyclic Redundancy Check and is employed in digital networks for checking/identifying any changes made to the data. Its sibling, SHA stands for Secure Hash Algorithm which finds its potent use in determining the integrity of data downloaded from the Internet, ensuring it is not corrupted.
Users not interested in knowing the function of these algorithms may find its entry in the context menu unwanted and would want to have them removed completely. Here’s how you can remove the CRC-SHA entry from the Context Menu in Windows 11/10.
Remove CRC-SHA entry from Context Menu
Open 7-Zip File Manager by typing 7-Zip in the Start search box and hitting the ‘Enter’ key.
Once located, open the program, select the Tools menu, and then hit the Options button.
Next, switch to the 7-Zip tab, just adjacent to the System. Under the Context menu items section, uncheck the checkbox labeled CRC SHA >, and then click Apply button.
That’s it! CRC SHA entry from the context menu will be removed.
If you see an error dialog with “An event was unable to invoke any of the subscribers” message, simply click OK button to remove the context menu entry.
We have already covered the 7-Zip tool in detail on our website. It is a handy file compression tool that helps you get the file size down without losing important data. As such, it has earned the reputation of a well-known open-source alternative to paid compression software.

How to add a context menu in Windows?
It can be achieved using the Registry method which is risky if the users end up deleting something. The better way to do it is using a context menu editor which can add, remove, edit Context Menu items in Windows. There are many apps that can safely do it, but make sure to back up the registry.
