How to Hide “CRC SHA” from the Windows Right-Click Menu
If you have installed or updated to version 15.12 of the file compression software 7-Zip on your Windows machine, you’ll see a new entry called CRC SHA in the context menu for files and folders. Let’s see why this entry appears and how you can get rid of it.
CRC (Cyclic Redundancy Check) and SHA (Secure Hash Algorithm) are a couple of standard methods used to test the integrity of data transferred over digital networks. Calculating these hash values can help you figure out if the data was corrupted after download.

If you have no use for the CRC SHA feature, or just prefer to use another dedicated tool to calculate CRC SHA values, you can get rid of this context menu entry. To do so, first open 7-Zip File Manager and head to Tools > Options. Under the 7-Zip tab, uncheck the box next to CRC SHA and click on the Apply button.
You can safely ignore any error dialogs that pop up. Now bring up the context menu to verify that the CRC SHA entry is gone.
Do unused context menu entries bother you? Or are you happy to let them be? Tell us your preference in the comments.
