Now, I don’t always check these and maybe this is why my workstation ended up in a bit of a mess. Today I needed to install MySQL Workbench so I headed off to download it and noticed the MD5 checksum beneath the link. There could of course be multiple culprits. Previously I had all manner of applications, games (including Steam) and utilities installed and the chances of finding what was causing the problems was pretty remote. If you want to re-enable the option, just check the CRC SHA check box in step 3.I recently paved my main development workstation after it started misbehaving (slow start up, some applications not opening consistently etc) and am trying to be careful about what I install on it going forward. If you right-click on any folder or file, you will no longer see the CRC SHA option. Here, uncheck the CRC SHA checkbox and click the Apply> OK button to save the changes. As soon as the Options window is opened, go to the “7-Zip” tab. This is where all 7-Zip installations are stored. In the 7-Zip window, select the Tools> Options option. First, open 7-ZIP by searching for ” 7-Zip File Manager ” in the Start menu. So it’s easy to remove CRC SHA from the context menu.ġ. 7-Zip gives you the options to choose the options you see in the context menu. Thankfully, you don’t have to edit the registry or change system files. After receiving the file, the other party can easily cross-check the hash code to verify the file’s integrity. The nice thing about this feature is that if you are sending confidential files, then generating and adding hash code is quite useful. When the hash code doesn’t match, you can be sure that the file has been tampered with. If the file’s contents are modified in any way, even if it’s a small change, the hash code will change automatically. If both hash codes are the same, the file is not modified. Then you can compare the hash code from the developer with the hash generated by 7-Zip. 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. What is CRC SHA?ĬRC SHA (Cyclic Redundancy Check, Secure Hash Algorithm) is often used to check file integrity. If you don’t like it, follow the steps below to remove CRC SHA 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.
