How to remove the CRC SHA option from the context menu in Windows 10

If you are using 7-Zip to open and create a ZIP file, you can see a new option named “CRC SHA” in the context menu when you right click. If you don’t like it, follow the steps below to remove CRC SHA from the context menu in Windows 10.

What is CRC SHA?

CRC SHA (Cyclic Redundancy Check, Secure Hash Algorithm) is often used to check file integrity. For example, if you downloaded a file from the Internet, you can use the CRC SHA feature to generate a hash code for that file. Then you can compare the hash code from the developer with the hash generated by 7-Zip. If both hash codes are the same, the file is not modified.

If the file’s contents are modified in any way, even if it’s a small change, the hash code will change automatically. When the hash code doesn’t match, you can be sure that the file has been tampered with.

The nice thing about this feature is that if you are sending confidential files, then generating and adding hash code is quite useful. After receiving the file, the other party can easily cross-check the hash code to verify the file’s integrity.
