Is there any Built-In Checksum utility for Windows 10 using CRC-32? I checked different answers which are old and mention certUtil, but that does not support CRC-32 or CRC-64.

Update: I had also checked Is there a built-in checksum utility on Windows 7?, however, that's an old question and does not specifically asks for CRC-32 and Windows 10 may have support for it now. That's why asking this.

There is a way to get the CRC-32 on Windows (since Win 7):

1. Right-click the file(s) you wish to get the CRC-32 for and click Send to → Compressed (zipped) folder.
2. Open the ZIP file using Windows Explorer, set the view to details.
3. Right-click on the detail header and select the CRC-32 column to be visible.
4. Resize columns so the CRC-32 is visible.
5. There you go!

7-Zip provides an additional Windows Explorer context menu entry from which checksums can be calculated:

1. Right-click the file you wish to get the CRC-32 for. A context menu appears.
2. Select the CRC SHA submenu entry.
3. Select any of the available algorithms: CRC-32, CRC-64, SHA-1 or SHA-256 to calculate the respective checksum, or select "*" to calculate all of them and additionally BLAKE2sp.

On my side it works, but you MUST be in the ziped folder via the windows explorer. Then, once inside, you can see the CRC-32 column option.

I opened the .zip with Windows Explorer, the right-clicked the file to show properties in order to see the CRC32 value:
