    In most cases, you should not merge checkpoints manually. You are supposed to use Hyper-V Manager, select the virtual machine in question, and use the checkpoint manager to either revert or remove checkpoints. That will ensure you merge them properly according to the checkpoints chain and do not mess up anything. Check the following guide for more information https://www.starwindsoftware.com/blog/vmwaresnapshots-checkpoints-alone-arent-backups.

    Hi Esra Kuştemir,

    According to the error message, please check to see which process is using the avhdx file. Run Process Explorer as administrator, select "Find" - "Find Handle or DLL..." and input the avhdx file path. The Process Explorer can be downloaded via this page.


    Best Regards,
